Sinew Backed Snakey Yew 5 Curve 42#@28″ (Bow No: 32)

Camo Sinew Backed Yew R&D longbow 42#’28” (Bow No: 30)

This bow was built from a really nice 6 year old English yew stave. In one of my recent blog posts which can be found here I talked about how I believe it is important to select the part of a stave which best suits itself to being used as the belly of a bow. This bow stave emphasised the points made in that post perfectly.

The stave used to make this bow was a 5″ diameter, clean, straight, horizontally grown English Yew branch stave. And as is often the case with yew branch staves, this one had all the small branches and pins located on it’s upper most side.

So when this stave got ripped down the middle on the band saw, the upper side was discarded as it was clearly useless for making a bow, but the lower side which would have been facing the ground was nice and clean and packed full of lovely orange pink compression strong wood.

The sap wood on this lower side was evenly distributed but a little on the thick side, so I reduced it down from about 1/2″ to about 3/16″. Since this stave was going to be treated to a nice bomb proof 3oz layer of sinew backing, I didn’t have to worry about violating the sapwood growth rings either, so I planed most of it off leaving behind only a even flat surface of sapwood which would act as a nice level low mass foundation for the sinew to stick too.

As the compression strong wood was used to build this bow, It took next to no set at all, even after being fully tillered and shot in, In fact this bow still holds 3″ of reflex after half an hour of post shooting rest. This resistance to string follow is not just a reflexion of the compression strength of this bows wood either, it’s also a measure of the protective influence that an elastic backing such as sinew has on the belly of a bow.

Many bowyers are unaware that sinew, being as elastic as it is, actually take the pressure off a bows belly by providing give to the back of the bow, especially at the top end of the draw cycle. This “give” from the crowned layer of sinew on the back negates the need for the belly to take on as much compressive force as it would have to if say it were backed with something lacking elasticity like other common backing materials such as bamboo or hickory.

Sinew is a wonderful material for building bio-composite bows when used properly. Too much sinew and a bow can end up too bulky and heavy to benefit from it’s elastic qualities. But get the weight and distribution right and it can really add some zip to a bow. So long as the sinew is adequately cured and the maximum draw length is achieved relative to the bows overall length.

It always amazes me how much faster an arrow will travel out of a sinew backed bow when it is drawn all the way back to full draw, as opposed to it being slightly short drawn. And this bow was one were the difference in arrow speed between 26″ and 28″ was really noticeable.

Over the chrono this bow was sending my 400 grain 600# stumping carbons at 152ft/sec, which made for some whistling arrows with a nice flat trajectory, and a great bit of fun out in the woods shooting her in.

I thought I’d try a camo effect on the sinew backing this time and followed the guidance given by Simon at Stonehill Primitive Bows. His great article on camo decoration can be found here and does a better job of explaining how I did the backing on this bow!

Sinew Backed Yew Longbow 50#@28” (Bow no: 28)

The stave I used to build this particular bow came from a storm damaged yew which had suffered the consequences of having had a massive oak tree fall right on top of it from some ones garden boundary back in 2023. It was brought to my attention by a tree surgeon mate of mine who was called in to clean the mess up.

Upon first inspection of the rather sad wreckage of what was a half decent sized mature yew (for around here at least), I didn’t expect to find anything other than possibly a billet or two. But to my absolute delight, and indeed surprise, I could see one solitary limb on the south side of the twisted broken mass of smashed branches, which had been completely missed by any part of the fallen oak.

Viewed from a distance it looked half decent at around 4-5” in diameter, but to be honest I was very much expecting upon further investigation to find the limb in question would be riddled with damage, side branches or other undesirable features. But instead, as if by miracle, I was further delighted to see that this solitary limb was not only fairly clean, but was almost perfectly straight along at least one angle when viewed side on.

Needless to say, for the princely sum of a few promised cold beers, I instructed my tree surgeon mate to CAREFULLY detach the limb so I could eye the stick over properly. And I was not disappointed. Nor was the lady whose garden had been trashed by the fallen oak, as whilst chatting to her as the chainsaws buzzed away, it turned out her late father used to build English longbows as a hobby when she was a young girl! You could not write it!! I swear we’re all in a simulation.

I got the limb home and inspected the ends of the log to see what the sapwood to heartwood ratio was like and inspect the growth ring configuration. And whilst the sap wood was a bit on the thick side measuring about half an inch thick at the fat end of the log, there was clearly plenty enough heartwood inside the log which would allow me to reduce the sapwood significantly without running out of belly wood outside of the pith line.

Now there has always been a lot of debate amongst the bowyer community regards what type of yew wood makes the best bows. Most of the advice passed around reflects upon the idea that thin growth rings dictate higher wood density and therefore the thinner ringed wood is stronger, therefore lending itself better to the purposes of providing for the needs of folk who like to fling arrows.

And whilst I have certainly found this general advice to hold some truth, especially with regard to yew timber which is growing straight up, I’m not at all convinced that this age old advice works well when we apply this logic to a side branch type stave, akin to the one I had before me on this occasion.

You see, a side branch of any tree is growing out horizontally. It does this to best expose it’s leaves/needles to the sunlight which would otherwise be masked by all the surrounding shad casting structure created by the canopy of the same trees own crown.

So a side limb, unlike a vertical growing “sucker” type limb, has to resist gravity each and every day of its existence due to its horizontal orientation. And it is this constant battle with gravity which is what causes the particular growth ring arrangement which you will always see in when looking at the ends of any side limb staves. Vertical growing limbs tend not to show the same ring configuration found in horizontally grown limbs unless the vertical limb is exposed to the prevailing wind. In that instance, the prevailing wind is acting like gravity by forcing the limb to withstand bending forces from a constant direction.

Take a good look at the end of any side limb stave whilst it is still in the round and you will quickly see that one side of the limb will have thin, tightly packed growth rings, whilst the opposite side of the limb will have much thicker, widely spaced rings. And the pith will be much closer to the more tightly ringed upper side of the limb. The limb I had just acquired was exactly this way.

All this visual info tells us precisely which side of the limb faced the sky when it was still attached to the tree, whilst simultaneously slapping us in the face with which side of the limb faced the ground. Thin rings faced the sky, fat rings faced the ground. Simple!

Does any of that matter I hear you say. Dam right it does! So pay attention to this next bit, especially if you are new to making bows out of timber you’ve paid hard earned beer money for!!

Those tight rings you saw in the cut end of your prized hunk of yew are telling you exactly where nature constantly exposed that limb to tension forces. And those thicker rings are screaming “I’m strong in compression!”

So which bit do we use then? We want wood that will give our bow a back which is strong in tension, but also a belly which is strong in compression. But we can’t use both halves of the limb, else we would just have a log, rather than a bow, right? Plus everyone says we want all that super dense tight ringy stuff right? Wrong!

In my experience of several decades working with mainly English yew in the form of less than 6” diameter side branch staves, you absolutely do NOT want to use the thin ringed side of a side limb type stave. Especially if the log in the round has a diameter of less than 4”. But let me explain why I’m telling you this before you call me an idiot and send me off to read the encyclopaedia Britannica of building English Longbows by the late legendary sole surviving participant of the battle of Agincourt, Dr. K. Now It’all.

Whilst all that tight ringed tension strong wood will indeed offer the bowyer a bow with a back which would be stronger than a rustic French cheese, that very same wood will produce a belly on a bow with the compression strength of one of them soggy prawn crackers which my local chippy hands out a bag of for free with orders over £30.

But if I were to use the heart wood as the bows belly from this side of the log, then I’d probably try heat treating it so that it would stand a better chance of standing up to all that tension strong sap wood. That said though, in my experience, belly wood from this thin ringed upper part of a horizontal limb will consist of all that pithy wood, which is really prone to splitting and checking when the heat gun comes out.

So why would the heart wood on the upper side of a horizontal side limb be weak in compression I hear you ask. Well it’s actually quite simple. It’s because the wood which sits on the skyward facing side of any side limb has one job to do. And that job is to resist gravity by being strong in tension. It is not expected to grow strong in compression because that’s the job of the side of the limb which grows facing the ground. And this goes for any species of tree, not just yew.

So what can we take away from this? Well the first thing to remember is that nature long ago realised the power of many thin layers. Those thin, tightly packed layers of growth rings are akin to the many thing laminations found in the blades crafted by master Katana sword smiths of ancient Japan, blades famous the world over for their tension strength. Insane force is required to break these relatively thin laminated blades which to this day are still famed for their durability, having been folded sometimes many hundreds of times.

The samuri didn’t care too much for blades with maximised compression strength you see. Make a blade too hard and it becomes hard to sharpen, prone to chip and most importantly, they become brittle. And brittle blades snap. Snapped blades aren’t much good in a sword fight. So strong, tension durable blades with good but not excessive hardness were more desirable than diamond hard blades.

I can’t help but wonder if our own medieval ancestors had a similar yearning for less destructible weaponry. I mean, If I was on a battle field, long bow in hand, would I be most concerned about the compression strength of the belly of my primary weapon, or would I care more about the tension strength of my bow’s back, and therefore the probability that it would not explode into kindling just as the opposition are charging. Hmmm, I think my bow staying in one piece might be more of a priority than a bit of string follow, don’t you!

But I back my bows. So do I really need the wood with all the tension strength? No I don’t. In fact a sinew backed, bamboo backed or even white wood lami backed bow is guaranteed to have a back which would be as strong as, if not stronger than, the very best yew sapwood on the planet.

My concern therefore is on using the best, cleanest and most compressing strong belly wood I can get out of a stave. Because a strong back, be it made by yew sapwood or an added backing like sinew/boo/ash etc, will over power a weak belly every time. And over time that over powering adds up to excessive string follow and possibly even crysaling on the belly. And whilst all the above might not produce a broken bow, it will produce a poor performing bow producing low arrow speeds and subsequently reduced cast.

These day I refrain from selling self bows. I just cant take the risk of someone buying and then mistreating a self bow only for it to end up being broken through misuse. And if one of my bows were to break at full draw then the possibility of someone getting hurt is not unreasonable. All it would take is for someone to leave a selfbow in a hot car or something similarly daft and BANG! And can you image the possible fall out if someone lost an eye or something. No chance

So every bow I sell nowadays has a bomb proof backing, both to maximise performance, as well as to mitigate risk. Risk not only to my customers welfare, but also to potential cause for litigation directed at myself or my business, because we are living in a time where common sense and personal responsibility appear in short supply, where as the blame culture appears the new norm.

Something else to consider when choosing which side of the limb to use as your bow is the location of all the difficult to work around features like knots and pins. Most side branch type limb staves will have the bulk of the knots and pins in the top and upper sides of the limb. And since the growth rings in this portion of the limb are much tighter, the heartwood mass will have less thickness of material between the bark facing the sky and the pith running through the limb. So often times the simply isn’t enough material in this side of the limb to make a bow. So once again we have more reasons to avoid the tension strong wood in the upper half of a horizonal growing side limb type stave.

By now you will have guessed that for this particular bow build I chose to use the downwards facing compression strong side of this particular limb stave. And I’m very glad I did. After 3 years of seasoning, the stave was pulled out of my barns rafters and the compression side of the log gave me a stave which was almost completely straight and with a good inch and 3/4 of relatively knot free heartwood before I hit the pith. I did end up leaving a bit of pith in the handle though, but since the handle on this build was going to be stiff, I did not need not worry about the pith providing a weakness.

After roughing out I homed in on a vague pyramidal flatbow type profile, 20″ of working limb each side, 10 inches of riser (4″ handle/3″ fades), and 8″ static tips. This would give me a 66″ bow nock to nock, which should be optimal for a 28″ draw. And I could see I had enough wood to make a 50ish pound bow.

After reducing the sapwood and letting the stave air for a week in the house, I put the stave onto a form which was very slightly reflexed overall, so that I could use the heat gun to knock of some of the unwanted and difficult side profile wiggle, and perfect the already quite good string alignment.

At this point the tips were only very slightly reflexed just like the whole stave was, so I was effectively tillering a straight stave to start. Once I had all 40″ of working limbs bending evenly, I flicked the 8″ static tips on a slight recurve form, re checked string alignment and sinew backed it. Off she then went for 6 months of curing time.

After a whole winter and spring of seasoning I could see that the sinew had pulled an inch or so of overall back set into the whole stave. This was fine and I envisaged most of that back set being lost after tillering was finished plus shooting in was completed, and sure enough this is what happened. The flicked tips held firm though and the limbs reverted back to straight though which landed her with about 2.25 inches of overall reflex after unstringing and resting. Perfect!

I managed to get 50 pounds of draw weight out of her as planned so got to finishing her up. For the tip overlays I fancied a nice bit of buffalo horn which had a little bit of grey streaking through it. Gorgeous stuff. For the sinew backing I wanted to create a camo, kind of birch bark type effect using my local earth pigments mixed with TB3, which would also water proof the sinew to a large degree.

The handle was wrapped in a rather lovely piece of soft, wrinkled red deer stag neck leather which I had bark tanned myself using sitka spruce bark, a bark which makes beautiful red/tan hides. The leather handle wrap was fitted with contact cement and lashed on with some roe deer leather lace I made last year. The arrow pass is bark tanned red deer hair on shin leather, which is just a great and very hard wearing natural material which makes the arrow whisper quiet when leaving the bow.

The finish is a few primer coats of shellac followed by many layers of danish oil. After pumice polishing the cured oil finish, Bees wax/linseed paste wax gave her a wonderful satin sheen.

I made her up a B55 bow string with nice small loops which keep the string tracking straight on those super fine tips. Silencers are wild brown hare bark tanned fur and make the shot super silent.

This bow turned out amazing. I loved shooting her in. One of my favorite bows for a while. Fast, quiet and little hand shock due to the low mass tips. She sends a 500 grain arrow over the chronograph at around 155 ft/sec and is just so much fun to shoot. And a real looker too.

Here are her stats:

Draw Weight: 50lbs at 28”
Mass: 825 grams
Length NTN: 66” (asymmetrical limb layout)
Width: 1 5/16″” at widest part
Tips: last 8” semi static reflexed, 3/8” wide

Bog Yew Sinew backed Longbow 52# @ 28” (Bow no: 26)

A friend of mine is a digger operator. He often ends up getting involved with projects like pond clearance/restoration type works. Whilst digging and dredging these kinds of places he often unearths all kinds of stuff. Much of my local part of North Devon is boggy wet ground. And whilst we don’t have those classic preservative peat bogs found elsewhere in the UK and Ireland, the bogs we have here are still sufficiently acidic and anaerobic enough to preserve certain types of organic mater which become submerged or buried within these often forgotten and neglected wild places.

Ages ago I asked this bloke to keep an eye out for any submerged oak he might come across, knowing that such a find would likely yield some very nice black ancient bog oak which would make for great carving or wood turning projects. So I was pleased to pick up a message from this chap last summer in which he detailed a find which he thought may be of interest to me.

He’d been working on an old estate property dating back to the early 1800s which had an overgrown cider apple orchard adjacent to a large silted up pond which he was in the process of reinstating on behalf of the estate. The pond was fed from a bog below the orchard which had a large earth hedge bank along one edge. And up on top of this hedge bank was a large, solitary, and likely very ancient yew tree.

At some point many years, if not decades ago, a large section of this ancient Yew had broke away from the rest of the tree and had fallen into the bog. And after decades sitting there this lump of yew had been completely consumed by the bog which had enveloped it with several feet of silt and clay.

Whilst digging out the bog this chap caught hold of this buried lump of yew and raised it up and out of the bog. Initially he assumed that it was just a big old piece of willow which had caved in from the edge of the bog. But once he’d pushed it up out the way he could feel how solid this particular timber was in comparison to other woods which would be well rotten and fragile by now.

He could also see from the broken ends of the tangled mass of wood that the preserved timber inside the muddy mess was a deep, bright orange colour, as opposed to a dull brown grey which you would have seen with most other species of rotten bog submerged tree.

Once he’d noticed the large yew tree standing up on the bank above the bog, he realised immediately that this buried timber was actually yew. And since he knew that woods like yew and oak will preserve in bogs, he thought he’d give me a shout in case I could make use of any of it. Trouble was he’d been distracted by other work and had forgotten about it for several weeks before telling me. Needless to say though, once he told me where it was, and that I could help myself to it, I was round there like a shot!

Upon first inspection of the mass of stinky mud and timber, I wasn’t very hopeful of salvaging much other than a few nice bits for making spoons and bowls etc. But after a bit of digging around, I was excited to find a fairly straight looking section of timber which was about 6 feet long, 5 “ in diameter and looked to have been undamaged by the digger.

With my silky saw I was able to cut the section of timber out from the rest of the fairly useless tangled mess of smashed branches and cord wood. And after wrestling this piece of timber out from the rest of it, whilst covered head to toe in mud and stink, I finally got a chance to inspect the log in more detail.

This log (like the rest of the wood) was completely free from even a hint of sapwood. The sapwood being free from tannins had rotted off decades ago. When a wood like oak or yew sits in a bog environment for any length of time, the sapwood simply rots off like any other wood would do. This is because most sapwoods including yew don’t contain the tannins critical for the preservation of the timber.

But due to the very high tannin content present within the heartwood of timbers like oak, chestnut and yew, the heartwood stays intact for decades, if not centuries, so long as conditions are suitably acidic and anaerobic enough to prevent decomposition.

And in addition to the anaerobic/acidic preservation of this tannin rich heartwood, there is another wonderful feature that our local bogs can bring about in tannin rich timber – and that is the unique colour change that takes place to the heartwood after many years saturated in our local ground water. This unique colour change is only attainable through this longwinded natural preservation process.

Due to our local underlying geology consisting of carboniferous sandstone, we are fortunate to have a large geological reserve of iron pan deposit within the sandstone bedrock endemic to our local landscape. This iron rich bedrock both surrounds and sits below our local bogs. And when these iron oxide deposits come into contact with our typically acidic ground water, the iron is dissolved into the water which in turn supplies high levels of dissolved iron rich water to these ancient saturated bog sites.

Given enough time submerged in such a iron saturated bog, the dissolved iron in the water reacts with the tannic acid in the heartwood of timbers like yew and oak. Slowly over time this turns the preserved heartwood a wonderful dark antique colour, which penetrates right through the entire log. Oak will often go almost jet black in this process. Oak preserved this way (“bog oak”) is typically prized and sort after by wood turners and carvers alike.

This salvaged pure heartwood yew log was clearly preserved and coloured right through as could be seen by looking at the end grain on the freshly cut log. I was blown away by the stunning bright rose gold colour which had penetrated the entire log. And from what I could see of the end grain so far, I couldn’t see any checking radiating in from the outside of the log either. Nice!

Drying checks in bog timbers is a common issue when wood is pulled out of its saturated boggy situation and suddenly exposed to air and sunshine for several weeks. Which unfortunately was the case with this particular find. But this log appeared to be free from checks and looked like I could potentially produce a bow stave. So once home it got hosed and scrubbed down so I could see what I had.

One side of the log was full of large knots and other problems, but the other side looked clean except for several whirls of pins situated with varying gaps between the pin whirls. I didnt dare to try and split this very precious stave, so I cheated and ran the saw through the middle of it splitting it into two halves. Inside was dreamy looking and also free from drying checks, mainly due to the stave still being saturated.

Keen to minimise the risk of drying checks developing, I decided there and then to get this stave roughed out to as close to final dimensions as possible so as to get way past the inner pith and reduce the mass to a point where I could feel confident that the stave wouldn’t start splitting as it rapidly dried out.

Once roughed out I used steam and a form to put a small amount of deflex in the middle of the riser. I also wanted to use this opportunity of having saturated wood to add a little gentle sweeping reflex into the entire length of the limbs to counter the deflex and reduce any potential stack felt at full draw.

Even whilst fully saturated this stave felt very stiff so I didn’t want to push my luck with the heat bending. So after heating, and once I was happy with the shape and approximate string alignment, I clamped her tight to the form and parked her up to dry out fully. After a couple of months the stave came off the form for inspection. No cracks visible and the light R&D shape had held tight. The stave felt a fraction of its former weight too indicating that it was now dry.

I’ve never before worked with bog yew so I was unsure of its ability to make a safe bow. Especially as it felt quite stiff. So to make absolutely sure this stave wouldn’t explode during tillering, or worse still, explode during use, I decided to sinew back it with 3oz of wild English red deer leg tendon sinew. Once the backing was completed and wrapped up on a drying form to retain the staves shape, the stave was put away again for another 8 months of curing time.

Once fully cured and cleaned up she tillered out to 55lbs at 28”. After tweaks, shooting in and sanding she finished up at 52Lb at 28”. She’s been a cracker to shoot and I had great fun putting a couple hundred arrows through her on my stump shooting forays. She’s sending 400 grain arrows over the chrono at 145fps at my draw length of 26” so I’m guessing at 28” she’ll be pushing 150+fps. She doesn’t stack and she doesn’t kick so she’s a real pleasure to shoot.

After refining the tips to minimise mass I fitted Wild English red deer antler tip overlays. I’ve also decorated the sinew backing in the exact same way as I’d described in my previous blog post which you can find here: Snakey Sinew backed Yew R&D Flatty (Zombie Killer) Bow No: 25 – Southmoor Bows

This time though I used a local Devon culm clay earth pigment as the underlying yellow/cream base colour. This contrasted wonderfully with the jet black sinew stands creating the mycelia look amongst the sinew backing. The tan wash to finish the look of the backing is once again concentrated spruce bark tanning painted on top of the creamy yellow clay pigment, then sanded/scraped through to expose the yellow/cream and dyed black sinew below. The tannin wash created a wonderful almost camo bark like affect on top of the creamy yellow, which almost looks like a natural creamy yew sapwood colour. This creamy yellow colour is fitting given the complete absence of any actual sapwood!

After sealing her up with many coats of shellac she got the polish and bees wax paste treatment leaving her with a wonderful satin sheen which realy make the rose gold almost translucent heartwood grain really pop. Especially beautiful are the pin whirls which I left nice a thick to remove any risk of pinching. The wood is a absolutely stunning even if I do say so myself!

For the handle wrap and lacing I used some of my home produced spruce bark tanned red deer leather. And for the arrow shelf/pass I used my own produced bark tanned red deer hair on shin leather. I love this material for arrow passes as its both silent to shoot across and really hard wearing.

The string is 12 stands of B55 fitted with double loops and my own produced bark tanned wild brown hare fur puffs for silencers making this bow whisper quiet to shoot.

So here she is. I hope you enjoy the look as much as I do, and please feel free to leave a comment below telling me what you think. This bow is now available to purchase in my ETSY shop here:

Snakey Sinew backed Yew R&D Flatty (Zombie Killer) Bow No: 25

This bow was built from a really nice clean English yew stave which had been put up in my barn rafters to season back in 2020. It measured 68″ in length and had about 8 inches of almost perfectly symmetrical distributed natural reflex running from end to end. This was obviously way too much reflex to be used as it was, but with some tweaking, I figured most of that reflex could be retained and put to great use.

The cleanest face on this stave was going to make the back of this bow and it only had a couple of tiny pins showing through the sap wood/bark. If it wasn’t for the fact that the sapwood was so thick, I could have just popped the bark off and called the back done. But I clearly needed to get the sapwood down from around 1/2″ thick to something more like 3/16″. This would maximise the potential to incorporate all the lovely heartwood this stave had to offer. Plus I intended to sinew back this bow so in all honesty sapwood retention wasn’t even necessary.

Knowing that the back of this bow was going the be backed with 3oz of Red deer leg tendon sinew, I didn’t have to worry about chasing a ring on the back. The sinew would make the back of this bow totally bomb proof so I just hogged off nearly all the sapwood leaving just a bit around the sides as an aesthetic compliment. I do like some sapwood on a yew bow, even if just to contrast against the heartwood in that classic “coffee with cream” composition. So I left enough sapwood around the edges so as to please the eye, but in truth this bow is comprised of mainly heartwood.

After flattening the back out evenly I laid out the bows face and thickness profiles so I could get the overall dimensions roughed out. For this build I planned on making a R&D pyramidal flatty but not too wide and with a slightly thicker rounded belly. So once the stave was roughly bow shaped I steamed the handle section and put the stave onto one of my R&D forms so I could bend a good bit of deflex into the handle. This was to reduce the overall reflex to something more manageable so it would be easy to string and less stressed at full draw.

Whilst the stave was on the form I used the heat gun to straightened out a slight issue with the string alignment. And I also took the opportunity to even up the reflex in both limbs so that they were as close to matching as possible. After a couple weeks for the handle section to dry out post steaming, I took the blank off the form and was happy with the overall shape and alignment.

With the deflex now added to the handle the blank was now carrying around 3″ of overall backset/reflex, which was far more realistic and functional. Next the blank was sinew backed, wrapped up and put away fixed to a drying form to retain the wonderful new shape and to allow the sinew to fully cure for 6 months.

After the sinew had cured out completely, the stave was inspected then very quickly tillered out to 26″. I find that blanks which have been shaped optimally prior to tillering are so much quicker and easier to tiller to full draw due to the even shape and profile achieved before the bow is asked to bend.

Once tillered to a point where the bow could be shot, I used it as my “stumping bow” for a couple of weeks of stump shooting out in the woods. The reflex held solid, as did the positive tiller and string alignment. Shot in she was registering 45 pounds of draw weight at 28″, which was exactly my intended target draw weight, so it was time to move onto finishing touches.

This stave was a very dense, high mass stave, and was noticeably heavier in the hand than other bows I’ve made of similar dimensions. So in order to minimise any kick that high mass limbs can produce upon string release, I opted to reduce the width of the limbs outer thirds as much as I dared in order to reduce the mass in the tips as much as possible and tame any kick felt in the hand.

This new narrower face profile in the outer thirds was achieved without running the risk of losing the static nature of the tips as I’d left the tips plenty deep enough in thickness to resist any bending. And fine tips of course need overlays to protect them adequately, so I opted to fit some lovely red deer antler overlays shaped to compliment the now adjusted and refined grace and flow of the outer limbs.

To decorate the bows back I fancied trying something a bit different. I’d been inspired recently by a pile of old beech logs which were full of that beautiful “spelted” black creeping web like fungal mycelia. I wanted to re create this creeping black fungal “mycelial” pattern and texture on one of my sinew backed bows, but using sinew threads dyed black to represent the mycelial component, set amongst a background of contrasting colour to represent the “growing medium”.

The primary colour I’d chosen to compliment the black of the sinew mycelia was a really nice dark red which I could create using a mix of my local iron oxide and carboniferous earth pigment. This combination of earth pigments creates that dark red blood colour, akin to what you’d find dried onto your sword after a busy day slaying a bunch of zombies! 🤣Perfect!

So I added a thin surface layer of new sinew threads to the already cured, established sinew backing. These new sinew threads however had previously been soaked in spruce bark tannin solution rather than plain water in order to hydrate them. And once fully hydrated with tannin they were then added to a little iron chloride solution which I make myself from wire wool and white vinegar. The chemical reaction which takes place between the tannin and the iron chloride resulted in the sinew threads instantly turning a stunning jet black colour.

These jet black sinew threads could then be glued onto the plain established sinew backing layer in a web like weaving pattern, just like those black fungal mycelia veins weave through a hunk of spelted beech wood.

Once these black weaving sinew threads were fully dry, I then painted the whole back with my dark red earth pigment paint mix. This dark red layer was then followed by a coating of concentrated spruce bark tannin solution to provide a slight chestnut brown overlay to the dark red paint below it.

Once it was all dry I then scraped through the chestnut tannin stain, and the dark red paint below that to expose the jet black sinew threads on all the high spots. This left the low spots red and tan coloured, and all the high sinew spots presenting as inky black veins weaving up and down the entire length of the the limbs. I was really pleased with how it came out and I intend to finish several more sinew back bow this same way, but with a variety of different colours and shades.

Once the back was all finished and the overlays/wood was all sanded up, I sealed her up with shellac. And after polishing her up she was treated to a nice satin beeswax/linseed paste wax finish. For the handle I fitted a lovely piece of my own home produced bark tanned roe deer leather stitched up with the same leather cut thin for lacing. And the arrow pass/shelf were both fitted with a couple of pieces of my bark tanned hair on roe deer shin leather.

I love the shape and finish of this bow and really enjoyed shooting her. She does not stack one bit, and despite all that reflex she is easy to string and silky smooth to draw. There is a slight kick upon release due to the high limb mass previously mentioned, but I got used to it after a couple of arrows and didn’t even notice it once I’d altered my grip a bit.

I found this bow very comfortable to hold at full draw, so was able to take a little more time shooting my full shot cycle. Subsequently I was able to shoot this bow with great accuracy over and over again. Across the chrono she was also performing how I’d expect too, sending a 400 grain arrow at around 150 FPS, which is what I’d expect from a 45lb primitive bow.

So here she is. I hope you enjoy the look as much as I do, and please feel free to leave a comment below telling me what you think. This bow is now available to purchase in my ETSY shop here:

Osage R&D sinew backed longbow 52#@27″ (bow no. 22)

Trying to get your hands on osage staves in the UK is hard these days, which is a real shame as osage is one of my favourite bow woods, second only to yew (due to sentimental value mainly). I bought this particular osage stave from Anthony Hickman over in Texas who has an Etsy shop which can be found here: HickmanCreationsShop – Etsy UK

Anthony sometimes has some nice osage staves in his shop for a reasonable price (by todays standards anyway!) And the stave which this bow was built from caught my eye as being worth the near $100 price tag. I could see from the photos from this staves shop listing that the growth ring thickness (and the composition of late wood to early wood) was very good, and that this stave carried no propeller twist or potentially problematic knots/splits etc.

At 62″ long, this stave was a little shorter than I’d ideally have liked, however I would struggle to get a longer stave shipped out to the UK without incurring a massive increase in shipping costs. So after a bit of consultation with Anthony, he managed to secure a not too absurd shipping price, so I decided to pull the trigger on this stave feeling pretty sure it would make for a very nice bow. And I’m glad I did!

So total cost including shipping, this stave came in just a whisker under $200, which is an awful lot of money for a hunk of timber, but unfortunately this is just the going rate nowadays for osage shipped to the UK!

The stave arrived on my door step in only 12 days which was bloody good these days. And after a thorough inspection of it, I was happy with what I’d received. Since the stave had the felling date written on the end grain, I knew that this stave was still fairly green. So I was a little worried that drying checks might have formed during transit from the states.

But I couldn’t see any signs of drying checks, other than what was obviously already present on the sapwood. And Anthony had made me aware of these sapwood cracks before I bought it. Since all the sap was destined to come off, the sapwood checking didn’t concern me at all, as more often than not, the cracks rarely ever continues deep into the heartwood.

Osage heartwood can check quite badly if dried too fast though, so I immediately painted the staves ends and the sapwood surface with TBiii, before putting it aside in my spare room to dry out for another 6 months. I kept weighing it each week so I could see when the weight loss would plateau and finally cease altogether. That way I would know when the stave was dry enough to start working on.

And by the early part of the summer of 2024, the weight lost had completely stopped, and I finally felt confident that I could begin sapwood removal and general roughing out, without running the risk of incurring drying checks from the rapid loss of any remaining moisture.

The sapwood came off nice and easy and chasing a decent latewood ring on the back was made simple by the fact that the first ring directly under the sapwood was perfect in it’s composition by being nice and thick, so I chased this faultless first ring and made that ring the back of the bow.

Now I had to think about design. This bow was destined to finish out at 60″ nock to nock, so being a bit on the short side, I needed to consider incorporating some design features to maximise draw length potential, without over stressing the limbs. Ideally this bow would go back to 27″, but I’d have to wait and see.

A 60″ bow drawn beyond 24″ will experience some “stacking” towards the end of the draw cycle unless some reflex is incorporated into the tips. So I planned to flick the tips on this stave, but not enough to be able to call it a recurve.

But flicking the tips alone would add at least 3-4″ of overall back set to this stave since the back of this stave was essentially dead straight. That much overall back set would definitely create the potential for overstressing the limbs of a bow this short, since the working sections of the limbs would only incorporate a max of 20-22″ of each limb.

So to counter the back set created by flicking the tips, I decided to deflex the 3″ fades either side of the 4″ stiff handle. Ordinarily I would have steamed the desired deflex into the centre of the handle, but I could see a couple of tiny drying checks on the belly side of the roughed out handle section, which would most likely have opened out considerably if I had attempted to steam bend the deflex into the handle.

The fades however appeared free of drying checks, so with the help of the heat gun, a shaping form, and a pile of G clamps, I pulled enough deflex into both fades to cancel out most (but not all) of the reflex, which I had now steamed into the last 8″ of the tips. After subtracting the deflex in the fades from the reflex in the tips, I was now left with around 1-2″ of overall back set. Much more realistic!

I opted for a simple slender pyramidal face profile on this bow, as this design works very well for woods like osage and yew. Since osage (like yew) is so strong in compression, I didn’t feel the need to go super wide with the limbs, so opted for limbs around 1 1/2″ wide at the widest section just outside of the fades, tapering down to 1/2″ tips (which I would leave static for the last 4″ in order to resist the reflex being pulled out of the tips over time with heavy use).

The handle section in the roughed out state was nice and deep, even once the bulk of the splintery rubbish had been removed from the belly side. So at 2″ thick, I decided to keep the handle a little deeper than I normally do. This would also enable me to retain nice deep fades too, so I fancied shaping them up to a nice crisp sharp ridge to create a nice aesthetic leading into the handle section.

In terms of character, this stave had one simple clean and featureless limb, and one limb featuring a small hollow knot (which I pegged), plus four small pin knots aranged in pairs in two different locations. This limb also had a small amount of lateral wave to the grain, which presented some nice edge contour to the face profile of this particular limb.

This limb also had the remnants of an old impact scar which must have occurred whilst the tree was still living. This old scar presented throughout the entire width and thickness of the stave, including the sapwood, and appeared as a pretty cool looking lighter coloured diagonal line of grain about 4mm wide running across and through the entire width and thickness of the outer third of the top limb.

This kind of impact injury to a living tree is usually as a result of another tree falling, or being felled into it. The tree heals rapidly by reinforcing the cells within the injured section with additional lignin and other strengthening compounds.

This healing process creates dense and interesting grain changes, which not only look nice, but are also denser and therefore stronger in both compression and tension than when compared to the surrounding uninjured wood. As such, these healed wound scars can be left within the working sections of a bow limb without any fear of weakness. In fact these sections are stronger than the rest of the limb.

As this limb clearly held all the character, I opted to make it the top limb which places most of the character closer to eye level. And since this bow was going to be asymmetrical, this more characterful limb was going to be 2″ longer than the more plain (but likely stronger overall) bottom limb. Since bottom limbs tend to take more stress over the years of shooting and stringing, they benefit from any additional design decisions which ensure optimal strength in this limb.

Since this bow was a little shorter than I’d have preferred, I decided to sinew back it. This would add significant durability to the bow, and it would also significantly reduce the amount of set which such a short bow would ordinarily take when being drawn back beyond 26″. I also consistently find that sinew backed bows retain their zip much better as the years roll by too, (so long as they are stored and cared for properly!)

So once the shape was roughed out and the back was suitably prepared, roughed up and sized ready for sinew backing, I added 3oz of processed wild English Red deer leg tendon sinew to the back of the stave with my own home produced hide glue made from cooked down red deer rawhide and sinew scraps. After sinew backing was complete, I then wrapping the stave up with bandages and put it away in a cool dry spot to cure for another 6 months.

By the beginning of this year (2025) the stave was dug out of hibernation for an inspection and I was pleased to see that the sinew was now fully cured. An additional 1″ of backset had been drawn into the stave as the sinew had shrunk down, so the overall backset was now almost back to where it was before I deflexed the fades.

This is very normal for sinew backed staves and I felt confident that after tillering, this extra 1″ of back set would likely fall out leaving something close to a more suitable1-2″ backset. And sure enough, after tillering to 27″, the stave was now back to around 2″ overall backset. Perfect!

After a good bit of early shooting in and a little fine tuning of the tiller, the bow seemed to settle into and hold the 1/8″ positive tiller really well. She was turning out to be a nice quiet snappy shooter, and a very enjoyable bow to accompany me about the woods stump shooting for a few weeks. not only did she not kick at all, but pound for pound, I recon this bow is possibly one of the fastest shooting bows I’d ever made.

Now to finish her up I decided to cut an arrow shelf into the handle as I personally love an arrow shelf and knew it would enhance the pointability of this bow significantly. And for the tips I went for wild red deer antler overlays.

Whilst the sinew backing on this bow provided great functionality, it did look a bit plain, so I decided to cover up the rather bland looking sinew with a couple of nice dark brown/purple cobra skins I’d had lying around for ages. The edges of the skins where then sealed and decorated with white dots made from ground deer bone dust mixed with glue and applied with a sharpened stick. I find that this edge work really helps to make the skins pop.

For the handle I ended up contouring the back of the grip to create a very slight pistol grip with the dip pulled up nice and tight to the arrow shelf so as to keep the arrow as close as possible to the top of the index finger of the bow hand. I really find that this little detail allows me to shoot a bow instinctively with considerably more accuracy through enhanced pointability.

After sanding I sealed her up with 8 coats of danish oil. Then the final extra fine sand and pumice polish was finished off with my favourite home constructed linseed oil/bees wax paste wax polish, setting her up for a nice deep satin look to compliment those snake skins and the wonderful golden yellow of the osage heartwood.

For the grip I found a nice rustic piece of home produced bark tanned red deer leather laced up with some roe deer leather thong. And for the arrow pass/shelf I fitted a couple of nice pieces of natural coloured hair on bark tanned red deer shin leather. Which is a better looking wild and rustic version of the commercially available “calf hair” leather the archery suppliers sell!

Fitted with a custom built ultra low diameter fast flight sting, I put a dozen or so 50# 550grain doug fir arrows over the chrono to see how she performed. The chrono recorded an average arrow speed of 168 FPS, which is about what I’d expected given how spicy she felt when first shooting her it. Easily capable of being classified as a “hunting bow” and very accurate and enjoyable to shoot split fingers and instinctive.

Yew Sinew Backed R&D Primitive for Ben 30#@22″ (Bow no: 21)

About a year ago I came across a short piece of round yew log which I’d kept with the intention of using as a billet. It measured 52″ long and about 3″ in diameter and was really nice and clean. After a bit of contemplation I wondered if I could get away with splitting it straight down the middle and getting two short staves out of it. So I thought I’d give splitting it in half a go.

For once it worked! Normally yew never plays ball when trying to split it, so ordinarily I would have taken it to the table saw, but in this instance I couldn’t be bothered, so I just set to it with an axe and wedges instead! Well low and behold it split just perfect! And no propeller twist evident either!

So now I had two nice clean straight, short and relatively thin staves. Should I splice them together and make a light weight full sized bow? Or, should I finally get around to making my kids a pair of proper character primitives, like I’d been promising them for ages. Of course, the kids won!! So this bow is the first of two bows which I made back in 2024. This one in particular is for my 10 year old son, and the other bow (which also came out great) I’ll blog about another time.

My son Ben has been wanting a heavier bow for some time. He’s really grown out of his first bow, a junior recurve which I bought for him when he was only 5. At 15#@ 20″, his recurve is now quite under weight for him and he’s probably drawing more like 22″ now anyway. So in the interest of keeping him excited about archery, I planned on making him something primitive and characterful, with enough punch to get him enthusiastic about flinging arrows again. And hopefully, if it didnt come out too light, it would be a bow that he can properly grow into over the next few years.

I wanted this bow to be a surprise for him, but at the same time, I also wanted to be sure that I built him something which he’d like the appearance and feel of. So in the interests of getting it right first time, I asked him to go through my collection of primitive bows and point out which style of primitive bow he liked the most. He chose the R&D sinew backed elm bow which I blogged about here:

He told me that he liked the shape (R&D pyramidal) and that he loved the rustic sinew backing effect that I’d created with that particular bow. He also made it clear that he wanted antler tip overlays, an arrow shelf cutting into a static handle, and a rustic leather grip. So now I knew what he liked, I set to work on one of the two yew staves with a plan to build a similar looking bow to the one he’d picked out of my collection, only made from yew and way more suited to a small, but rapidly growing young man!

After roughing the stave out to something close to final dimensions, I spent a bit of time heating a nice even Reflex/Deflex side profile into it using a mixture of steam and dry heat applied whilst using a shaping form I built a while back specifically for kids bows.

The sapwood was only about 1/4 – 5/16″ in thickness so I just left the back of the stave as it was directly under the bark. Ben had already made it clear that he wanted his bow to be sinew backed “like the Indians did”, so after I had the bows shape and profile locked in, I sinew backed it with red deer leg tendon sinew applied with TBIII, and parked it in a dry, cool place to cure for 6 months.

After waiting through the entire summer and autumn of 2024, the stave was finally ready to dig out of slumber so I cut some temporary nocks into and got it on the tillering tree. Within a couple of hours I had the tiller pretty much done but was a little concerned the weight was still too heavy. And at 40lbs at 18″, I was right!

By reducing the limb width a bit I managed to shift about 5lbs of draw weight without moving the tiller off, but I still had at least another 8lbs to get rid of before I could close the gap on the target draw weight of around 30Lbs at 22″. So I carefully scraped away at both limbs checking constantly for tiller change until I reached around 30lbs at 20″

Happy that the rest would probably fall off through shooting in and final sanding, I shaped the handle, cut in an arrow shelf and took it out for a spin in the woods with a hand full of 350 grain 35# stumping arrows which I’d built to accompany the bow when I gift it to Ben. They were a little stiff so I ended up keeping them a tad longer than I normally would so as Ben’s draw length increased with his age, his arrows should still be safe for him to use. Hopefully I’d just reduce the point weight as his draw length increased to keep them flying true.

I had a wail of a time over the next few day trying to shoot a 22″ draw without an anchor, and have to say, I actually got half decent at snap shooting from the hip like the Comanche did in the archery videos Ben’s been watching lately on YouTube ! After a couple hundred arrow and a good bit of fun the tiller seemed to be holding just fine, well for split fingers at least, (pinch grip not really being my thing!) So I decided to move on to finishing touches.

Tip overlays from red deer antler went on easy enough and once I had them shaped up, I could envisage going really fine with the tips so as to create a really sharp but elegant look to what is after all a rather petite bow. And of course by minimising the mass in the tips, I would also help to ensure that this little bow was maximising energy transfer to those nice light arrows.

Whilst I had the rasp out thinning down the tip tappers, I also saw fit to do a bit more handle shaping which brought the grip into a nice comfortable shape. Ben is a bit finicky about bow grips and hates bulky handles! This handle now had a slim profile and a slightly dished out belly side to it, which felt really natural in the hand. I figured he’d like that. I certainly did!

Ben had said that he wanted the same textured sinew effect on his bow that I’d done with the Elm primitive he’d selected from my bow collection. So Instead of filling and smoothing out the rough sinew on the back like I often do before adding snake skins etc, I simply gave it a light sand to knock off the snaggy raised ends of of the sinew stands. Then after sanding the whole bow, I masked off the belly and edges of the bow, and painted the whole sinew backing jet black with a paint made up of shelac and my local Bideblack earth pigment.

As a bit of a edge decoration I painted a row of red earth pigment dots along both edges of the sinew backing to give a buffer to where the black met the light coloured sapwood along the edge. And after writing on the draw weight/length and adding my bowyer’s motive, I sealed her up with Danish oil, topped off after polishing with my favourite paste wax.

For the grip I fitted a nice rustic natural bark tanned piece of roe deer leather sticked up with a thinner piece of the same material cut into thin leather lace. The cut leather edges of the grip and lace where then “aged” with Iron chloride to create that natural patina look that old worn leather gets on its edges. A coat of the same paste wax I used on the wood was applied to the leather grip and polished up to give a nice low gloss/satin water proof finish. The arrow shelf/pass was then treated to a couple of pieces of bark tanned “hair on” red deer shin leather to add a nice rustic, primitive look whilst maintaining functionality and durability.

Ben was absolutely over the moon when I presented the bow to him. Of course he wanted to take it out right away and shoot it, but since it was dark outside, I managed to get him to wait until the next day! He had a great time zipping his arrows off at stumps situated off in the next county, and proceeded to loose two of his new arrows in the process! Doh!! But never the less he had a blast, and has shot his new bow many times since with a newly rejuvenated enthusiasm for archery!

Despite Ben not quite yet being able to get the bow all the way back to his normal 22″ draw length, he is definitely getting it back to around 19-20″ now more often than not. So he’s probably drawing something like 25 ish lbs from his new bow at the moment. Which is still a lot more than his usual 15lbs! And he could immediately see how much more speed and power his new bow had in comparison to his little old recurve.

Anyway, I hope you like the photos below. If you like the look of this bow and think that your child might like something similar built for them, feel free to get in touch as I will consider commissions for unique pieces of work like Ben’s bow. Either message me through the contact page on this website or contact me through the Southmoor Bows Etsy shop and we can discuss designs/materials/prices etc.

Sinew Backed Primitive Elm R&D Longbow 48# @ 27″(bow: 20)

It’s been ages since I made myself a bow. So when I uncovered a forgotten Elm stave which I’d had up in the barn rafters for a couple of years, I rather fancied turning it into my next favourite stumping primitive.

Whilst the stave was fairly clean, it did have a knarly looking end section which looked more trouble than worth the effort to work around. So I opted to cut this end off. This only left me with 61″ to play with. That’s not much for a white wood bow.

A white wood bow this short, intended to be drawn back to my 26″ draw length, would stack unless the tips were flicked. But flicking the tips on an otherwise short and straight stave would probably overstress the limbs.

As the added reflex was only to reduce stack, not add speed, I opted to deflex the handle section/fades so that it would cancel out the added stress from the recurve induced throughout both outer thirds. This is something that I tend to do routinely now, as even just a whisper of R&D makes for a much smoother, less stacky draw.

And as this white wood bow was always going to be a tad on the short side of ideal, to make sure that there would be no risk of his bow blowing up on me in a few years time, I decided to sinew back it with 3oz of Red Deer leg tendon sinew. Whilst it’s always a hassle and a massive faff to sinew back a bow, in addition to the extra durability sinew backing brings, it don’t half add some resistance to set, not to mention a fair bit of extra zip!

The stain on the wood is iron chloride, and the light dark effect on the sinew was achieved by painting the rough sinew backing jet black using my local “bideblack” earth pigment mixed with TBIII, which was then sanded along all the high spots to reveal the underlying natural sinew colour standing proud above the black sinew valley bottoms.

Edge work was done with the same black paint and the white dots are deer leg bone dust mixed with glue. I personally really like this kind of edging as it really makes the face profile pop.

Tip overlays are wild Red deer antler, and the handle/ arrow pass is covered with my home produced traditional spruce bark tanned wild roe deer leather. The wood was finished and sealed with shellac.

Given the sinew component, this bow took a full year to build from start to finish, but I’m really happy with how she came out. She is fast and light in the hand, and produces zero hand shock. Quiet as a feather and very pointable too. Whilst I’ve yet to put more than a couple of hundred arrows through her, she is already rapidly becoming one of my favourite woodland bows.

Here are the stats:

Draw Weight: 48lbs at 26”
Mass: 660 grams
Length NTN: 59.5”
Width: 1 3/4” at widest part
Tips: 5” semi static 3/8” wide at the nocks.
Back: Moderately crowned with a pyramidal face profile.
Belly Profile: Working limb sections flat with rounded corners, transitioning at the tips to ridged shaped cross section.
Tiller: Elliptical. 1/4” positive
Brace height: 5 1/2″

Sinew Backed Ladies R&D Yew Primitive (38#@26″) Bow no. 18

This bow was built from a short, thin but nice straight English yew stave which had been propped up in the corner of the barn for at least three years. It was too short to make a bow fit for a 28″ draw, and it was also a bit too narrow to produce a draw weight much above 30lbs.

After a bit of thought I decided to see if I could turn it into a short ladies or teens bow. The stave was pretty straight and without much wiggle. The sapwood was about 10mm thick so I reduced it down to about 6mm. The growth rings were a couple of mm thick so staying true to one growth ring on the back was quite easy.

Since the stave was so short, I wanted to reflex the outer thirds of both limbs in order to reduce any stack experienced at full draw. In an attempt to avoid over stressing the bow with too much overall reflex, I also wanted to deflex the handle as a means to minimise the risk of the limbs taking on excessive set. This was a fairly short stave after all.

After roughing out, the R&D shape was achieved by using a mixture of both steam and the heat gun to persuade the stave to conform to the shape of one of my wooden R&D forms. After the desired shape was achieved, the stave was sinew backed using wild Red Deer leg sinew and hide glue.

After being put away to cure out for 6 months, I finally got around to digging the stave back out for tillering. As is often the case with pre shaped staves, this one tillered out very quick and came off the tillering tree roughed out at around 42# at 26″.

After a good bit of shooting in, and a quick retiller to let off the top limb a bit more, she was finally pulling around 38# at full draw. And after a bit more shooting in and with the tiller now holding fast, I was ready to think about decorations, overlays and general finishing.

For tip overlays I laminated a couple of pieces of deer leg bone onto some buffalo horn. As a decorative backing, I chose to use a couple of nice wild sea bass skins which came from a cracking lure caught open reef fish which I’d been very fortunate to catch on the north Devon coast last summer (photo of the fish at the bottom). The reef bass often take on a nice dark colour around this part of the world and I’d been itching to use some as bow backing material for ages, so was keen to make this my first attempt.

The skins were fitted with TBiii and were edged with a black paint made from a mixture of hide glue and a locally produced earth pigment called “Bideblack”, which I’d collected from the cliffs directly behind the reef beach where the bass was caught. The white dots where made from mixing deer bone dust with hide glue and were applied with a pointed stick.

The handle cover is my own home made spruce bark tanned wild red deer leather, died with some Iron Chloride which I’d earlier made from wire wool mixed with vinegar. The Iron chloride reacts with the tannins bound within bark tanned leather, turning the leather dark black.

The lacing is done with my own bark tanned roe deer hide, and the arrow shelf/pass is bark tanned red deer shin leather cut from an edge piece which still had some hair on it. After staining the leather black I thought the natural golden brown colour of the hair stood out great, giving a pretty cool unique look. Deer shin leather makes for great arrow pass/shelf material as it is very dense. This makes it super tough and durable whilst still being nice and thin.

As you’ll see from the photos, there were three knots in this stave, I wanted to incorporate all three knots into the bow’s character so I deliberately left them nice and thick and wide to avoid any likelihood of them producing a weakness, or an unsightly pinch.

Two of the knots were unsound and needed to be dug out and refilled, so rather than dowel them like most do, I decided to improve their aesthetic appeal by filling them both full of with a mixture or epoxy and natural/stained yew dust. This gave both knots significant extra strength, as well as a much more natural knot like appearance. I think they look far better that the customary heartwood dowel and glue approach which most bowyers use to fill knot voids.

After sanding buffing and burnishing she was treated to 8 coats of danish oil and a buffing down with fine pumice and oil. Then a final application of paste wax to leave a nice satin finish.

I was really pleased with how this one turned out. She’s a smooth drawing, whisper quite little thing and the sinew helps send a 380 grain arrow out there at an impressive 145ft/sec. Not bad for a R&D primitive with only a 26″ draw!

This was the Bass from which I used the skins in the build. The black sooty looking pigment on the shale rocks behind is what I used mixed with hide glue to make the black paint which edged the skins.

Yew snake skin and rawhide backed Deflex/Reflex Longbow. 56#@26” (Bow No. 13)

This bow was built out of one of a bunch of yew branches which all came from a group of yew trees which produce some really beautiful orange heartwood. In my experience, no two yew trees produce the same quality of timber, however all of the branch staves which came from these particular trees have a good ratio of heartwood to sapwood and they all have this wonderful bright orange heartwood.

This fortunately means that none of the branch stave cut from these trees are likely to need much, if any sapwood removal in order to optimise limb composition. This is really helpful as the growth rings on these particular branches are nice and tight which is definitely what I prefer in terms of optimal yew bow wood. But tight rings on yew staves with undulating backs makes chasing a ring quite a challenge! Particularly if the stave has lots of additional character – which is kind of what I like, and is oftenwhy I chose to use a particular stave in the first place!

This particular branch stave was pretty clean across one obvious potential face, however I have to admit that the glaringly obvious deflex was not an immediately attractive quality. Fortunately the deflex was evenly distributed through both limbs and the handle section. This deflex amounted to about 3” worth so was going to require a bit of thought and consideration.

Whilst thinking about how I’d work around all this deflex, I remembered seeing a couple of beautifully made primitive osage bows made by a well know and accomplished bowyer in the US call Mike Yancey. Mike owns and runs Pine Hollow Longbows out of Arkansas. If you haven’t seen any of Mikes work, then go check out his stuff. He’s done a few really interesting podcasts and has a few youtube videos which you might find interesting. His website is here: Traditional Archery – Pine Hollow Longbows and his youtube channel is here: Pine Hollow longbows – YouTube

A couple of Mikes signature bows have quite a bit of deflex deliberately built into their design. This has always intrigued me as I’d always assumed that lots of deflex would cost a bow significant cast. Mike seems unfazed by this though and counters it to some extent by flicking the tips. But even with the tips flicked, some of his shorter bows still carry a good couple of inches of deflex overall.

Despite all that deflex, Mike and his customers report that those same bows shoot fast, hard, smooth and quietly. So with this particular branch stave already carrying a lot of natural deflex, I decided to have a go at producing a bow with a similar side profile to the shorter bows which Mike makes. That way I could encompass as much of the natural deflex into the design of this bow as possible.

My plan was to produce a medium length (56-58” N to N) flatty with an elegant pyramidal front profile. I planned to flick the tips since they were relatively knot free, and I planned to keep the last 4” of the tips static. Mike uses Osage almost exclusively so I couldn’t be sure that his basic design profile would work for our English yew. So with this in mind I opted to keep reflexing down to a minimum with a view to offsetting some of the deflex but definitely not all of it. The flicked tips would also avoid excessive stack too given that this shorter than average bow was going to get tillered to 26”

The handle section on this stave was full of beautiful orange heartwood which I wanted to maximise the potential of as a feature, so I opted to keep the handle thick enough to show off all that wood. As a result of keeping the handle so thick, the handle would obviously end up rigid. This would result in the 4” handle section plus 3” fades taking 10 inches of the bow out of action. The 4” static tips would take a further 8” out of play too. This would leave only 20” of each limb available to work. That’s not a lot of moving wood to accommodate for a full 28” draw length so I opted to keep this bow to a 26″ draw length. Since 26″ matches my own draw length, that suited me just fine! So all of that natural deflex would now act as a bit of a buffer and would mitigate the risk of building a bow that was starting to resemble quite a high stress design. Maybe that’s why Mike deliberately builds in so much deflex on his high performance short osage bows.

This particular stave was fairly easy to rough out as the grain was quite uniform for the most part. I often find that our local yew wants to tear out, even when away from knots and other typical features. I have come to think that this isn’t necessarily due to propeller twist, but is more to do with our generally higher wind speeds stressing the limbs of our local yew into growing with an uneven cross section in order to brace itself against our stronger than average prevailing winds. In fact propeller twist is something that I seldom experience with our local yew. I wish the same could be said of our white woods!!

The face of this branch stave which I’d planned using as the back of the bow had previously acted as the top of this branch as it grew on the tree. As a result of this, the growth rings were tighter in this section of the limb when compared to the underside of the branch. The result of this growth is often that the pith of the branch ends up running closer to the face that acts as the top of the branch. This was the case with this particular branch. As such, the pith would need digging out of both limbs in order to optimise for limb compression strength and minimise the risk of bucked heartwood on the belly.

By the time all of the pith was out it was clear that this bow would end up incorporating a shallow hollow limb type appearance in the inner thirds of both limbs. This was just fine in my eyes as I find that a HLD cross section limb profile looks nice and enhances performance. So out came the gouge and the swan neck scrapper and soon I had both limbs free from pith and down to a nice even thickness of between 14 and 12mm distributed evenly between all the humps and bumps and twists and turns.

With the face profile and limb thickness roughed out, I got on with flicking the tips with a simple jig and some dry heat from a heat gun. I decided to keep the flicked section to a long gentle sweep rather than the usual 6” of more aggressive curve. This would allow half of the flicked section to do some work whilst keeping the last 4” completely static.

Next a small amount of dry heat was applied to the top limb fade in order to correct a small amount of string misalignment. Then it was time to cut some tillering nocks. I was quite happy with the side profile of the bow at this early point and was keen to see what the stave looked like during the first few pulls on the tiller tree. Other than an obviously stronger bottom limb, the first pulls looked nice. A bit of re balancing of the limbs to improve the elliptical tiller I wanted brought my eye back in so I could see that there were a couple of spots on both limbs which needed to be let off a bit. After that the rest of the tiller came together pretty quick.

The natural deflex and added reflex had created a shape which looked very nice once reaching full brace. Since this bow was symmetrical, I wanted to try and maintain a ¼ positive tiller throughout the tree tillering process knowing that the bottom limb on a bow this length would likely take on a fair bit of stress and a little set if shot split fingers.

Brace to 22” went smoothly but it was clear by now that a fair bit of weight removal would be necessary before pushing out to 26” as she was currently very heavy at 22”. I was aiming for a bow around 55-58 at 26” so stopped when I got to 55 at 24”. I’d shoot in the last 2” of tiller then adjust accordingly. So with the temporary nocks serving to let me shoot her in, I gave her a couple of weeks worth of stump shooting to settle in properly.

After a lot of shooting, all looked good and the positive tiller had held up well albeit reducing down to about 3/16″. It was clear by now that this design of bow was very efficient. In fact I was really impressed with the power and speed this bow was demonstrating. I shot stumps with her using some old battered 30″ 500# Gold Tip Traditional Classics which are as close to bomb proof an arrow as you’ll ever find and subsequently an excellent choice for blasting stumps with. They are also a very heavy arrow. Tipped with insert, ballistic collar and 150 grain stump heads, these things are coming in at 575 grains so I was expecting this bow to respond to them like it was being asked it to throw logs! But she was sending them on their way like my 50# Satori sends them. I was impressed!

Back at the workshop after all the shooting in the tiller still looked great and the finishing process could begin in earnest. I wasn’t intending to put this bow up for sale in my shop as this bow was intended to be a gift for a mentor of mine but I still wanted to enhance the durability of the bow’s back. So on went a couple of premium quality wild red deer rawhide strips to bomb proof her back. You can buy them here: One Matching Pair of Wild Deer Rawhide Strips – Etsy UK Then on went a couple of buffalo horn tip overlays. Last but not least, I wanted to use this bows rawhide covered back as a canvass so that the back could earn the right to sit next to all that gorgeous orange belly wood. So on went a whole King Rat Snake skin from tip to tip.

This bow had an arrow shelf cut into it to increase functionality. The shelf is cut pretty close to centre which has reduced arrow fussiness considerably. I refrained from wrapping the handle so the handle wood could shine. Covering up that gorgeous bright orange handle wood would have been criminal in my opinion!

After a very quick and easy re-tiller to account for the addition of the backings, I was ready to sand and polish her up. Then a little black and white artwork was employed along the boundary between the wood and the backing to make the contrast between front and back really pop.

To seal her up I gave her a few baths in Tung Oil to give her a wonderful satin finish which really suits yew in my opinion. Finally I built her a 12 strand B55 flemish twist string with nice small loops to keep everything in line whilst hanging onto those tiny nocks. Two Wild beaver fur silencers dampened down the tiny amount of sound that remained on this already whisper quiet bow. Fur silencers also look pretty cool and in keeping with the overall primitive theme in my opinion. You can buy them here: 1 X Pair of Beaver Fur Bow String Silencers beaver – Etsy UK

I have to say that I’m really impressed with this bow. And even though the wood that this stave provided was a major contribution to the efficiency and performance of this bow, I simply can’t help but think that this deflex reflex profile enhanced the smoothness of the draw and the retention of power which might have been lost through set born from a straight or reflexed starting point.

I’m going to continue to experiment with this profile further. I want to confirm whether or not the performance of this bow can be readily replicated in other bows of similar stature. I’m also now curious to see how bows of other woods would perform when designed this way. I will keep you posted on my findings!
