I’ve often thought about using yew as a material for tip overlays. As attractive as the idea is though, I’ve always been conscious of the idea that yew heartwood is a little bit on the soft side to prevent string wear over time. Well at least on a heavy bow. I’m not convinced that a 50lb bow would suffer from too much trouble in this regard, and expect that the old adage that yew self nocks will cut through is only really applicable to bows with a war bow like weight.
With all that said, up until now I’ve avoided using yew heartwood as tip overlays, just in case they do fail. And also because I’ve never been short of alternative overlay materials such as buffalo horn, bone, antler, bog oak etc. And since these other materials look amazing on just about any bow, I’ve never really had the need to explore using yew. Well up until now that is!
The other day I chanced across the large mature yew pictured bellow. After admiring the size and beauty of this magnificent tree I couldn’t help but notice that it had a short section of very dead and blackened limb protruding from near the base of the tree.
This dead branch was so blackened on the outside that it drew me in for further investigation. Upon closer inspection this dead limb had clearly died off many years ago and had seen all of its white wood rot away leaving behind nothing but pure heartwood. I was curious to discover to what extent this black outer coating penetrated down into the underlying heartwood, so I sliced away at a small section with my pocket knife to expose the underlying material.
In the pictures above you can see where I sliced into the branch. The blackening was only surface level but directly below this blackened surface was a really nice, dark layer of heartwood. The first thing I noticed about this underlying dark layer of heart wood was how very hard it was. My pocket knife is pretty sharp but was struggling to make headway as I tried to dig down through this layer.
At this point my interest in this dead branch peaked. Unlike normal soft yew heart wood, this outer layer of rock hard yew heartwood would surely make for a very functional, not to mention beautiful, tip overlay material.
After further investigation of this exposed layer I could see that the reason for this hardening was a common process which many conifers perform when parts of their structure die off. In order to protect its self from pathogen ingress, conifers seal off dead parts by pumping sap bourn resins into the areas which form boundaries between dead and living parts. These resins fill the cells of the trees dying tissues and they eventually set hard like a super glue does once soaked into the pores of wood. The protective outer layer that this process provides protects the living parts of the tree from being colonised by pathogens which might otherwise colonise dead and dying part of the tree in close proximity to living parts.
All the bush crafters out there will have seen this process manifest as the “fatwood” phenomena which leads to the production of resin saturated dead branches on many species of conifer. Bush crafters will remove these “fatwood” branches from dead pine, spruce and fir trees to facilitate fire lighting, as these dead resin saturated branches are highly flammable and aid significantly in fire lighting processes.
I’ve never witnessed resin deposits in yew before however, so this was a learning opportunity for me. The resin deposit I was seeing here in this dead yew limb was nowhere near as extensive as occurs in many other conifer species but was clearly sufficient enough to have created a 3-4mm thick layer of very hard wood. This would be more than enough material to position against the back of a bows limb tip preventing the likelihood of a string cutting through a string grove cut across an overlay made from this particular yew heartwood.
Given that this limb was not affording this magnificent tree any benefit, I decided to “borrow” it for some experimentation. So making sure to leave several inches of dead resin filled wood at the base of the branch to offer protection to the living tree, I cut the dead limb off.
Initially I was a bit concerned with all the splitting which can clearly be seen in the photo above. But after closer inspection I could easily envisage finding plenty of spaces in between the myriad cracks to wrestle out plenty of overlays.
The wood was initially quite wet so after cleaving the rounds down into more manageable sizes I brought them indoors and sat them on top of the fireplace to dry out thoroughly. Splitting was minimal and they were a joy to work down to a suitable profile.
Below are a couple of photos of my first attempt at making overlays from this log. I think they look pretty cool. The string groves are cut right down through the lighter, softer heartwood up to the darker, harder resin impregnated section. This arrangement means that the colour contract between a white wood bow and the yew overlay is maximised, whilst also ensuring that the string only makes full contact with the hardest part of the overlay.
I’m currently toying with the idea of trying holy as an overlay material since it is pretty hard and a beautiful bright white. I imagine it would contrast sharply against something like a dark stained white wood. (Watch this space!)
If you found this article interesting then keep an eye out in your own local area for some resinous yew so you can give yew heartwood overlays a go. I think there is now a place for yew in my selection of tip overlay materials. What do you think? Please let me know in the comment section below!
This bow started out life as a 2-3” branch which I harvested a couple of years ago. Given all the knots, kinks and wiggles, I knew it was going to be a challenge to turn this ugly little stick into a bow. Yew is one of those few bow woods which can be incredibly forgiving however, so I decided to give it a go!
The main challenge with this branch was going to be placing a bow back somewhere on it, and in a way which would keep the back from including any of the larger more fragile knots. One particular face was cleaner than the rest, but by choosing to use this face as the bows back, I would have to deal with a significantly deflexed 8” section which would have to fall somewhere between one of the limbs fades and the middle of that limb.
The branch measured only 68” long so I would have little opportunity to manipulate the handle location anywhere other than in the approximate centre. Given all the potential weak points on this branch, I did not dare to aim for a bow any shorter than 66” nock to nock.
I knew that I’d be able to steam out some of the unsightly deflex in what ended up being the top limb, but given all the knotty material in this deflexed section, I dared not try to straighten it out completely as the likely hood of one on the knots popping was very high.
After roughing out the basic limb thickness and face profile, I set about reducing the deflexed section with steam. After that was taken care of the small amount of string misalignment plus a little twist was corrected with some dry heat. At this point I also steamed in the gentle recurves. Now I had a more workable and predictable shape, I could then start to think about the final limb width and general profile/cross section.
The heartwood content of this bow was not great and the sapwood was about 8-10mm thick. The back was covered in small raised pins so chasing a ring was totally out of the question. And since the likely-hood of this branch ending up as firewood was high, there was no way I would consider investing time and effort to sinew back a risky bow like this, just to get away with violating the back in order to improve the ratio of sapwood to heart wood.
As with all branches, the pithy centre was biased towards the side which had the tighter growth rings (1-2mm) which happened to be on the same side of the branch which I’d chosen as the back. This meant that the pith was currently contained within both limbs and ran right through the handle.
Whilst I have no problem with the pith running through the handle section or even the thicker parts of the fades, I do not like leaving the pith in the working parts of the limbs. Experience has taught me to expect cracking, splitting and even fretting to occur when the pith runs close to the surface of the belly material.
Given that the crown on this branch was significant and the pith was currently buried inside the roughed out limbs I opted to hollow out both limbs to match the crown, whilst hopefully getting deep enough to remove the pith at the same time.
This worked fine but left me with very little heart wood. In fact the sapwood to heartwood ration was around 70/30%. Not ideal so I decided to take the sides in as the sides were entirely sapwood. This reduced the limb width down from about 1” 7/8ths to around 1” 5/8ths.
Now that the pith was out of the limbs and the heartwood sapwood ration had been improved, I didn’t have a great deal of bow left to play with, so I had to be realistic with the outlook. I guessed she would probably make for a finished bow around 35 40lbs at best. So I was really suprised when I actually managed 51lb at 27”!
I tillered the bow to 27” as my brother will likely get this bow. His draw length on a good day is about 27”. I took the tillered (albeit unsealed) bow stump shooting for a couple of weeks with only tillering nocks cut in and a leather strip wrapped around the handle to double as a grip and arrow pass. After a hundred plus arrows I checked her over for faults but found none.
I was expecting some of the steam correction to pull out in the deflex section but it didn’t. The finished bow looks like it has a very positive tiller but it is deceptive. The deflex section right out of the top fade is what gives this bow the look of excessive positive tiller.
In reality, this bow feels very well balance through the entire draw cycle and the limbs time together great when I shoot it with split fingers. I’ve shot enough bows over the year to be able to feel when a limb is weaker than the other. Despite the appearance, this bow is very well balanced.
After double checking the bows tiller by feel and then by tiller tree, I confirmed that the top limb is only slightly weaker than the bottom limb which is perfect for both my use, and my brothers use, since we both shoot split fingers.
It never ceases to amaze me how you can take a bow which looks to be tillered very well, only to draw it back and feel that torque on the wrist that you get when one limb is significantly stronger than the other. Nowadays, when it comes to final tiller, I place more emphasis on feel than I do on appearances. Where wooden bows are concerned (especially character bow) appearances are incredibly deceiving!
After shooting and sanding, I weighed her again and she was settled in at 48lbs at 27”. Happy with that I fitted her static recurved tips with a pair of Red Deer antler tip overlays, and I inlayed the arrow pass with a patch of buffalo horn. For the handle I chose a simple leather grip fitted after sealing the finished bow with 8 coats of Tru-Oil.
This bow put a smile on my face. I could well have imagined this bow breaking mid tiller. Not only was I impressed that she held together, but she actually ended up a being a proper little looker too. So much character and more than satisfactory performance has made this little bow one of my favourite character bows so far this year. (I have others to show off soon!)
In terms of performance, with a 12 strand B50 string on she sent a bunch of 450 grain arrows over the chronograph at an average speed of 143ft/sec. Not bad for a knarly old branch bow! Mass is 560 grams and she carries about ¾” of set immediately after unstringing which returns back to almost straight after resting.
This is one of the many “lockdown bows” which I made through 2020/21. Having been furloughed for a couple of months I took the opportunity to tinker with a pile of difficult staves which I’d had kicking about for years. A good time to try and sort the potential staves from the firewood!
This bow came from one such stave. It was nothing more than a branch to be honest but was still one of the better potential staves in terms of its overall shape. That said, It was still flawed to some extent with masses of pin knots on what would be the back side of the stave. It also had quite a lot of deflex across the entire length of the back. Especially in what would be the bottom limb.
Despite the imperfections I committed to making a bow from this stave and had long since promised to build a mate of mine a yew recurve. So I made it my mission to honour my promise using this far from optimal Yew branch. The basic plan was to build a 66″ nock to nock” 50-55lb recurve flatbow.
The stave had nice tight growth rings of between 1-2mm thickness but unfortunately carried little heartwood. The sapwood on what would be the back was too thick at around 12mm thick, but due to all the tiny raised pin knots, it would be impossible to properly chase a ring down to a better sapwood thickness without violating the back around all the tiny raised knots.
A trick which I have used many times before in this situation is simply to accept the violation of rings on the back but mitigate against limb failure by sinew backing. So that’s what I decided to do with this bow.
The stave was only 3″ wide so the crown was moderate. Rather than try and reduce the sapwood thickness in a rounded fashion as would be necessary to mimic the natural crown, I decided to just flatten the whole back with a rasp. In doing this I was able to work down to approximately one sapwood growth ring right down the centre line of the bows back and follow that from one end to the other maintaining a totally flat back profile.
Now that I had nearly 50% of the limb represented by heart wood, I roughed out the general limb thicknesses and finalised the face profile. In order to counter the significant deflex I recurved the tips with steam and performed a small amount of dry heat correction to line up the tips and correct some small string alignment issues. Then it was on with 3oz of deer leg sinew, glued on with my own home made sinew glue.
After the backing was completed I wrapped the whole thing up for a few days in cloth strips to keep the sinew from peeling away from inside the recurves and around the handle.
Once I could see that the sinew was dry I unpeeled the wrapping so I could take a peek. To my disappointment some of the sinew had dried out to form some small fissures. I put this down to one reason. Taking way too long to apply the sinew!
I’d timed the sinew application with the kids getting home which invariably led to a pile of requests, Dad jobs and other frivolous distractions all when I’m trying to slap on my glue soaked sinew bundles. Lesson learnt!!
Anyone who has done any amount of sinew backing will tell you that the best sinew jobs are done quickly and smoothly whilst the glue is still warm and not allowed to set up in between bundle applications. Each fresh bundle of sinew wants to be laid down alongside its neighbour before the neighbouring bundle has started to “Gel”. That’s where I’d gone wrong.
All the distractions had led to me applying bundles as and when I got chance as opposed to in one fast fluid operation. This meant that by the time my next sinew bundle got applied it’s neighbour has gelled up reducing the ability of the fresh sinew bundle sticking to it’s neighbouring bundle.
The result is bundles of sinew separating apart from one another when the bundles start to shrink during the drying process. I should add however that the adhesion between the glue soaked sinew and the bow’s back is not affected by this phenomena.
As disappointing as the end result was, the imperfections that I was seeing in the dried backing were only aesthetic. The functionality of the bow’s backing was completely unaffected.
So onwards we went. After the cloth wrappings had been removed and re-tightened several times over the initial drying period (a week), the wrappings came off and the stave was set aside for nearly a year to cure thoroughly.
I’d kept the limbs asymmetric to try and mitigate for the lower limb deflex which was now substantially less than it was. This was due to the sinew backing pulling the stave back about 1 & 1/2″. Now the deflex was only about 3/4″ in total which was a massive improvement as before backing the natural deflex was about 2 “. After coming out of hibernation, deer antler tip overlays were fitted over the top of the sinew and the tillering began.
In order to preserve as much heart wood on the belly as possible I opted to create a slightly rounded albeit mainly flat belly. An arrow shelf was added in the form of a scrap piece of deer antler.
The bow was quick and easy to tiller and looked nice pulled down to 28″. At this point the weight was 58lb which was about right for the guy who would be getting this bow.
Before finishing the bow I shot stumps with it for a couple of weeks then re adjusted the tiller slightly to weaken the top limb just a tad bit more then called her done at 55lb at 28″ with a neutral tiller. (The owner of this bow shoots three under.) To finish I coated the sinew with a good covering of Titebond III so seal and smooth out the sinew. After sanding it was on with 8 coats of Truoil to finish.
The handle was covered with a piece of scrap leather and the same leather in reverse was used to protect the arrow pass.
I really like this bow. It’s a bit heavy in the hand (630Grams) due to the extra weight from the sinew but isn’t really noticeable once you get in the swing of shooting her. The limbs are an even tapper from 1″ 3/8ths at the fades down to 1/2″ at the tips.
This bow made for a snappy shooter which I really enjoyed shooting. I shot her over the chrono to see if she was quicker than usual and, whilst hardly getting blown away by the speed, I was quite happy with the 162ft/sec average that I got with a 500 grain arrow. That’s not bad for a stick and string bow!
I built this bow about this time last year after coming across a knarley 2 1/2″ thick yew branch which had been kicking around in my yew stash for a few years. It was one of those branch wood staves which no conventional bowyer would have used for anything other than firewood. And I must admit, I nearly added it to my own firewood stack!
The branch was relatively straight across the cleanest face but had several bumps, knots and wiggles distributed between 8 sections of reflex and 7 sections of opposing deflex. The sap wood to heartwood ratio was about 2-1 with sapwood clearly forming the majority of the branches volume.
I decided to give it a chop about with the axe to see what the belly would look like with most of the waste wood chopped away. To be honest, it looked like it might just about make a bow.
My main concern was that the pith centre looked like it might not come out without reducing the thickness to a point where the bow would end up very light. But after long string tillering it looked like the limb thickness would be clear of the pith whilst leaving behind enough wood to make a light to moderate weight bow. But the pith would run through the handle along with a drying check which looked unsightly.
My original plan was to produce a stiff handled flat bow with a high crowned D section cross section. But I just couldn’t put up with leaving that horrible crack running right along the length of the handle and fades. So I decided to gouge all that split wood out from the handle and the fades leaving me with just enough wood to function as a handle albeit a bendy character handle!
I made the limbs symmetrical and a max width of 1″ 5/8ths. Tiller was 1/4″ positive. Fades about 2″. Antler tip overlays were fitted after sinew backing so that the overlays could sit on top of the sinew. Nock to nock the finished bow measures 64″.
The single layer of deer leg sinew backing was a hedge against the knots but in hind sight was completely unnecessary. That said the sinew has kept the set to absolute zero. In fact before I sinew backed the bow I tillered it as a self bow to 28″ and was content with the 44lbs draw weight and the 1″ of permanent set after shooting in over a hundred arrows.
But I had a small pile of sinew to do something with so decided to stick it on the back of this bow to see what effect it would have on such an undulating and knarly high crowned back. The results were better than expected!
After sticking 2oz of sinew on with sinew glue the bow was wrapped up and shelved until Nov 2022 so it had about 10 months of curing time. During this time the bow had straightened out and the permanent set had disappeared and didn’t reappear even after retillering and significant shooting in. The weight had jumped up too so I ended up with 50lbs at 28″ with no set at all.
With no skins to cover up the sinew I decided to just leave it bare. I gave the whole back a coat of Titebond III to help smooth down the rough sinew before finishing the whole bow with Trueoil. I refrained from wrapping the handle so that the gouged out handle could feature as part of the overall character of the bow.
An attractive knot is in just the right spot to function as an arrow pass so I didn’t bother with an inlay. The final look is certainly rustic but to be honest, I quite like it!
The handle contours naturally in such a way that the crook acts as a locator dish which feels quite comfortable in the hand, even with the handle bending upon drawing. That said, unless I hold this bow lightly I do notice a bit of hand shock. I think that this is down to the mass of the tips which is probably not helped by the presence of the sinew. In fact, this bow is a little bit on the heavy side thanks to the backing. The total weight of this bow is 760grams! Yikes!
I actually like shooting this bow and it gets quite a bit of attention from others who often see it and comment with questions like “What the heck is that!?” Once they’ve shot it though they usually ask if I can make one for them!
I built this bow from a totally green 4” diameter English Elm log which came my way back in the spring of 2022. The bark slipped off perfectly which was good in that it was easy to remove, but meant that the bow finished out lacking the wonderful cambium camo effect which I absolutely love to see on white wood selfbows.
As with most Elm logs above 3” in diameter, this log had some beetle damage which resulted in this log only producing one stave in the end. This was a shame as the log was clean, straight and carrying little twist. If it wasn’t for the beetle damage then I’d have got two nice staves from this log.
The damage free stave was slightly reflexed in the handle area but had a nice straight face profile with tips almost in alignment with the handle centre. After recurving I chose the top limb so that the string would favour the left side of the riser section since I’m a righty. I laid out the staves with symmetrical limbs and a handle section which would accommodate a 4” grip with 3” fades.
Both limb sections had a tiny amount of deflex mid limb so I could see the potential for a deflex reflex riser/limb profile. Since the stave was 66”, long I laid out the bow to finish 64” nock to nock. This is ample length to safely accommodate light recurves on a nice and wide limbed Elm flatbow.
I planned to finish with a solid and safe selfbow around 50lb at 26”. Flicking the tips on a bow this length shouldn’t stress the limbs, but as a back up against chrysling the belly, I kept the limbs around 1” 7/8ths wide for the first 2 thirds tapering rapidly down to ½” wide static flicked tips in the final thirds of the limb.
This staves back had some crowning to it but not really enough to warrant hollowing out the belly although in hind sight I probably should have. That said the flat belly/low crown cross section profile appears to have retained adequate compression strength and has withstood any fretting, even after much shooting with a held anchor. The deflex/reflex profile probably helped here too and certainly made the tillering process easy. The draw of this bow is also very smooth with very little stack.
This stave was simple and quick to tiller given the very even natural profile and in no time I was left with a snappy, low volume, low mass flatbow (570 grams) which is very pointable and is an absolute pleasure to shoot. Brace height is 5 1/2” and the tiller is 1/8” positive. This is one of those bows which when braced plays a note with one of those wonderful high frequency resonances when the string is plucked. Dinnnnnnnnnng!
I could have produced a heavier draw weight from this stave but I like bows around the 50lb mark at my draw length of 26” so I aimed for that and got it. There is no hand shock since the tips are low in mass and the grip is very comfortable to hold with a loose grip. The bow shoots hard at 26” and shooting a 9gn/lb arrow (450gn) over the chronograph produced average speeds around 156ft/sec.
The stave was fairly plain with no wiggle to speak of. Nor were there many significant quirks like knots etc so I decided to stain the bow so as to draw out the main feature which was the beautiful grain on the belly. A contoured grip and arrow shelf made a bit more of a feature out of the handle section and antler tip overlays helped to pimp up the limb tips a bit.
The arrow rest is not cut to centre but the paradox isn’t a problem anyway. An arrow in the 45-50lb spine range shoots well in this bow.
The handle received a light tan leather covering which was also used in reverse to serve the arrow pass. The stain is an oil based Dark Oak colour finished with many coats of truoil.
This little project was initially just intended to explore how much twist and malformation could be corrected through drying a badly mishappen green field ma[le stave whilst clamped to a form. The stave came out so well that I decided to persevere with it and the project ended up turning into a full bow build. The end result is a nice sweet shooting deflex reflex selfbow. The full build can be seen here: https://southmoorbows.com/build-along-field-maple-deflex-reflex-character-longbow/
As is typical of Field Maple, this stave lacked much in the way of colour or grain so I decided to stain it. Antler tip overlays and a simple black leather handle/arrow pass compliment the natural character of the bow. The limb cross section ranges from crowned/convexed to almost rectangular with some mild valleys, troughs and hills around the few small knots and naturally wavy grain.
Measurements are as follows:
Length Nock to nock: 66″
Limb width at widest point – Top: 2 1/8″ Bottom:2 1/8″
This project started out as a simple short term experiment. I’d had my eye on a clean but crooked and twisted Field Maple limb for quite a while. Trying to envisage where within the limb I could salvage a stave from was difficult. The limb was about 4.5” thick and had a section about 80” long which was relatively clean. In general the limb was sound and free from large knots, pins and other major imperfections.
The 80” section that showed most potential for making a bow stave did have other issues to consider however. This most usable section was badly twisted and had a significant sideways bend in one half of the stave. There was also a very large amount of natural reflex in what would be the middle/handle section.
To start with, I just wondered if it would be possible to improve the shape, twist and alignment of such a misshapen stave whilst it was still green. I’ve performed many shape corrections on green staves before, using forms and clamps, but I’d never before tried to correct asymmetries in a stave which were as server as this without using fully seasoned staves manipulated with steam bending.
I’ve worked with clean Field Maple on many occasions before so understand the potential this wood has for making a very good white wood bow. In the past I’ve used dry heat to correct minor twist and alignment issues on fully seasoned Field Maple staves. I’ve also used steam heat bending on Field Maple staves for more significant bending such as recurving tips or bending handles for alignment issues etc.
The amount of twist and reflex in this Field Maple stave however was way more than I’ve dealt with before. My expectations for this stave were not great. I envisaged the stave resisting the significant forces necessary to bend and twist this green stave into a better shape.
I also expected cracking or delamination to occur in the mid section due to the shear amount of force than would be necessary to pull the twist out using clamps and a drying form. But my expectations were proven wrong!
The reflex in the handle section was going to remain no matter what I did but this was fine as I could imagine this stave potentially turning into a reflex/deflex longbow. By leaving the limbs full width out to the tips I was able to get significant leverage from the clamps positioned on the edges of limbs. This leverage enabled me to crush down on the side of the limb that was pulling away from the form due to the limb twist. This worked really well and the twist between the fades and the limb tips came out beautifully.
The overall shape was made much more even by using the reflexed form too. By forcing the tips to line up with the handle centre I was also able to correct most of the significant string misalignment. Throughout the end of August I left the clamped stave outside in the sun on hot days.
The stave came indoors for a week once the temps dropped and was left on one of my window sills which catches all of the mid day sun. This window sill is like a green house and serves to quickly force dry staves very well. After the stave had been allowed to dry on the form for about a month I removed the clamps to inspect the results.
The overall twist was reduced from nearly 70 degrees to about 5 degrees. The massive reflex was tamed to something much more manageable and the string alignment was now only a little off to one side. The stave now actually looked perfectly workable with plenty of character remaining, so instead of calling the project done I decided to see what I could do to turn this stave into an actual finished bow.
My next job was to get this stave down to some realistic dimensions. It would be unlikely that this stave was totally dry so by getting close to final dimensions I’d soon get this stave fully dried and ready for tillering.
Field Maple is a dense wood so these 14+mm thick limbs will need quite a bit of reducing in order to get them to a point where the tillering process can begin. I’m going to aim for 14mm fade end thickness tapering down to 10mm side thickness at the tips. I want the tips to do a very small amount of work on this bow so I will reduce them down to 10 mm but keep away from them when tillering. This should Keep the last 6” of the tips stiffer than the working section of the limb, but without leaving the tips carrying unnecessary mass which would be the consequence of keeping the tips thick enough to ensure that they are completely static.
When I work the face down to rough dimensions on any bow, I always let the grain dictate the limb shape. This avoids creating grain run out which in my experience is a fast way to limb failure.
Until the cambium has been thinned right down I can’t get a true handle on the real thickness of all parts of the limb. I tend to leave quite a lot of cambium on a stave right through to the limb thickness reduction phase as the cambium layer acts as a good layer of protection to the back of the bow. A cushion against scrapes and scratches is a good idea whenever the back of a bow will be seen on the finished bow. Since this bow will not be backed the natural appearance of the first layer of wood below the cambium will be displayed on the finished bow so taking care to protect the back of this stave is important.
Personally I like the appearance of self bows which have a little bit of cambium left on the back of the bow. This little bit of cambium adds to the beauty of the finished bow and confirms to the observer that the back of the bow is in actual fact the very wood which once grew directly beneath the bark. No ring chasing necessary. This remaining cambium also creates a beautiful camouflaged effect on the back of the bow.
As tempting as it often is to hog at the cambium with a draw knife it is too easy to nick the underlying wood and compromise the back of the bow so I always proceed with caution using a scraper for raised spots in particular.
The back of this stave has an undulating topography which presents as hills, valleys and troughs. If I were to leave the belly completely flat in cross section then the hills on the back would act as stiff points and the valleys and troughs would act as weak spots. To counter this potential problem I contour the bellies on my wide limb bows so that the belly topography matches that of the back but in reverse. To achieve this I use a mixture of gouges and curved scrapers to remove material from the belly directly opposite the hilly thicker spots on the back. This enables me to leave material behind over the thinner valley and trough areas of the back. This affords them extra protection and creates a truly even thickness across the entire width of the limb.
I use my fingers to feel the thickness across the whole limb. If I find a thick spot I’ll remove material from the belly until the thickness is the same as everywhere else nearby. I’m aiming to end up with limbs which are an even taper of 14mm – 10mm thick along the entire length and width of the bow. This means that areas of the back which present as high crowned will have a corresponding belly section which is effectively hollowed out to counter for the crowned back. This stave has a mixture of high crown plus flatter sections with hills, valleys and troughs so the belly will end up being far from flat.
The next job was to put some deflex into the limbs to counter for the reflex in the handle section. I do this with the flat back of a form and some padded blocks and a clamp to create the right shape. I’m aiming to create most of the deflex around the first third of the limb about 6 – 12” out from the ends of the fades.
I’m carful where I choose to heat as I want to flick the tips on this stave and realise that if I make an early heat correction to a limb near the tips then the steaming of the tips which takes place later will pull the previous heat correction back out when the heat from the steaming travels down to where the twist correction was made.
I’m a fan of longbows but enjoy the lack of stack which a recurve benefits from. Whilst not wanting to go for a full recurve design on this bow I did like the idea of balancing the deflex and reducing stack a little by flicking the tips on what is aimed at finishing up a longbow.
After half an hour over the pan I fit my steel ruler to the belly of the stave using a small G clamp and a packing block to protect the back from clamping pressure. I frequently do this as it really helps prevent the belly tips from delaminating when being bent over the recurve form. The extra support of the flexible steel ruler simply stops a splinter lifting on the belly which is the kiss of death to many would be bows. This trick is especially important if your stave tip belly is not presenting as one growth ring, which is the case here. On this particular stave, both tips span two growth rings so delamination is a high probability without the ruler acting as a brace.
I have to be careful at this point to make sure that the deflex that has already been put in is not lost. I make sure to protect the deflex by setting up the paddle so that the leverage is the direction that promotes flexion to the limb rather than extension. This trick will ensure that the deflex is preserved.
I thought about including an arrow shelf on this bow and certainly had plenty of wood left with which to do that, but I fancied going old school and figured a simple handle for off the knuckle shooting would complement the natural lines of this stave best.
The depth of heat penetration that you get with this method is significantly greater than can be achieved with a heat gun. After 45 minutes the handle section is scolding hot so the stave is manipulated into alignments and then comes off the heat and is allowed to cool for an hour. After the jig comes off I check for alignment and am happy to see that the correction has brought string alignment back to just favouring the left side which is perfect for a right handed archer such as me.
This stave is heavy but almost braceable right out the gate. After about 15 mins of long string tillering on the tiller tree the bow can be strung at a 6” brace height.
The left limb in the picture above is the bottom limb and is slightly weaker than the right limb which the top limb. I shoot split fingers so want this bow to finish out with an 1/8″ – 1/4 ” positive tiller. This was opposite to what the bow was doing at brace so I needed to reduce to top limb to swing the balance the other way. This is fine though as at this point, the bow is still quite heavy. I’m a short drawer so I’m aiming for 50lbs at 26”. At the minute I’m still getting 50lb at 22” so I spend an hour carefully reducing the weight of the top limb and tickling away at any stiff spots overall.
I’ve now got the stave down to 53lb at 26″ on the tillering tree. The extra 3lbs will likely come off as the bow is fine tillered and sanded after being shot in. both strung and unstrung I’ve got a really nice even balance of reflex in the handle and tips combined with a nice bit of mid limb deflex. The flicked tips haven’t pulled out and the string alignment is still just slightly biased towards the left side of the bow which for me as a right handed shooter is perfect. No signs of chrysaling anywhere on the belly and no splinters to be seen on the back. Time to get a handle wrap on and shoot her in.
I always shoot a couple of hundred arrows through all of my unfinished bows before sanding and finishing. I’ve learnt that a bow which has been meticulously tillered on the tillering tree will move considerably through actual shooting. After two hundred shot you know what you have. I then recheck my tiller and adjust accordingly.
I love using deer antler for tip overlays on primitive bows. Not only does antler function well as a material for tip overlays, it also looks amazing. And given that primitive bow hunters both past and present have relished the opportunity to hunt deer, it seems fitting that a material from such a prestigious quary species should be used to enhance and embellish a primitive bow.
In this article I’d like to share my 4 most important principles to making beautiful, functional and efficient deer antler tip overlays.
For this project, you will need the following tools, materials and equipment:
An unfinished bow stave without nocks already fitted.
Suitable sized pieces of deer antler cut from the coronet end of an antler.
A wood saw with small to medium sized teeth.
A rasp/coarse file/belt sander.
Titebond III wood glue.
Spring clamp.
Vice.
Wet kitchen towel.
Tile saw (optional).
Chainsaw file.
Sandpaper 80/100/120 grit.
Principle # 1 – Select the right type of antler.
For the purpose of making deer antler tip overlays, you will not want to use a piece of antler which is full of the pithy porous honeycomb like structure that you will typically find in antler from sections anywhere other than the coronet end of the antler. Antler from the coronet end is very nearly solid all the way through. Antler from anywhere else is effectively hollow from all the micro holes. Maximise the strength of your antler tip overlays by ensuring that your overlay material of choice is solid, or at least as close to solid as is possible.
Principle # 2 – Achieve the basic shape and profile of your tip overlays BEFORE you glue them on.
Don’t be tempted to simply saw your antler into blocks and then glue then on with a view to shaping them later. Shape then first before gluing!
I often see people take a tip overlay material such as antler and simply glue a chunk of it to the tips of their bows. Once the glue has set, they will then set about shaping the overlay.
The problem I see with this method is that the desirable character of antler is mainly at the surface level. It therefore cannot be optimised for inclusion in the final shape and appearance of the overlay unless these characters conform to the desirable shape and profile of the finished overlay.
If a chunk of antler has simply been glued on to a bow tip before shaping, the shape of the chunk of antler will likely be nothing like what is required of the finished overlay. As the functionality of the overlay will take precedence over its beauty, optimising shape and profile will rank more important than aesthetic appeal.
The absence of appropriate shape and profile will necessitate the removal of the surface material. This will result in the removal of much, if not all of the surface material along with all of the desirable characteristics and features of antler.
For example, if a chunk of antler with beautiful pearling is simply stuck on to a bow tip before shaping, the likelihood of that pearling remaining within the final shape and profile of the overlay after surface material has been removed is very low.
To put it another way, the amount of material which will need to be removed in order to obtain the final shape and profile of the overlay will have resulted in much of the antlers character being removed.
By shaping your overlay before gluing them on you will be able to optimise the inclusion of desirable features whilst prioritising the removal of unwanted material from areas which have undesirable feature. Examples of a desirable features might include the natural colours, shapes and pattern of pearling. Example of undesirable features might include the porous backside of the overlay or a plain spot which lacks any colour or features.
Once I have selected a good piece of antler I will select which part I want to use based on its appearance and its internal structure and integrity. The piece I choose to work with will then be ripped down the middle to create two equal albeit oversized slabs of antler.
It is important that the angle of your overlays taper is nice and low. I aim for around 10 degrees. This will allow for easy stringing of your bow. If you choose too steep an angle, you will find that when you come to string your bow, the string loop meets the transition to the overlay and comes to an abrupt halt rather than slipping smoothly over the overlay and into the string groove.
Now that the basic shape and profile is complete, there will be very little work to do to the top of the overlay after it has been glued on. Since there will be no need to take any more tools to the top of the overlay, the risk of damaging the back of the bow where the overlay transitions to wood is reduced significantly.
Principle # 3 – Create the strongest bond possible.
A bow is only as strong as its weakest point. Any joint is likely to be a weak point. With that in mind it is critical that all joints be made as strong as is possible.
Your bow string will sit directly on top of your tip overlays and receive the full force of your bows draw weight. Any torque will be felt by the tip overlays too. It is therefore imperative that the bond which you establish between your tip overlays and the back of your bow is made as strong as possible. We can maximise the strength of our tip overlay joint by ensuring three things have been attended to.
Firstly we must maximise the contact surface area between the components which are to be joined. In this instance we are talking about the roughly shaped overlay being jointed to the wooden tip of our primitive bow.
By making sure that your tip overlays are at least 1” long we are providing adequate surface area to create a large enough contact area to create a strong enough bond. Personally, I like to make my overlay a little longer than this and typically make my overlays between 1 ½” and 2” long. On static tips you could make your overlays even longer of course.
Let us assume we have made sure that our tip overlays have a contact surface area which is at least 1” X 3/8”” wide. Now we must optimise the contact between the two surfaces by making sure that the two faces to be joined together are as well fitted to one another as is reasonably possible.
By flattening the stave tips ready to receive the overlays we can begin to check how well the two surfaces match up. I like to take my time here and make sure that the two contact surfaces meet up perfectly before gluing. Don’t rush this part. Take the time to make sure that the two surfaces match up without any gaps.
Go careful when you start to flatten your bow tips. It is easy to get carried away and compromise the growth ring which forms the back of your bow. If this happens beneath your overlay, then it will not be an issue as the overlay will distribute the stresses back to the outer growth ring.
If, however, you accidently cut through the growth ring on the back of your bow ahead of your overlay then you will likely break the whole tip off your bow when you come to draw it. Always make sure that the transition from bow back to overlay occurs on the actual growth ring which makes up the back of your bow.
Wood absorbs glue much more readily when freshly exposed wood cells make up the surface layer to be glued. If you leave your prepared bow tips for any amount of time then, the freshly exposed surface layer of the wood will lose some of its ability to soak up the glue. Freshly exposed wood is hydrophilic. However, even after a short amount of time has lapsed, the exposed wood surface soon reverts back to being somewhat hydrophobic. So, get you bow tips and overlays matched up and glued up ASAP for the strongest possible bond.
The second thing to consider when trying to create the strongest possible bond is which adhesive to use. I’ve tried all kinds of adhesives over the years but always find myself coming back to Titebond. I’m currently using the MK III stuff and am happy to report that it really is a great adhesive for gluing most natural materials to wood.
If you are planning on using a stain on your finished bow then try and avoid getting glue anywhere other than the contact surface of you overlay area. Any glue that gets on the back of your bow will get soaked into the surface layers of the wood. This creates an impermeable layer which can prevent the absorption of stains at a later date. If this happens then you may need to intervene in order to avoid unsightly patches of unstained wood. You may have to scrap/sand away the upper layers of wood cells from affected areas in order to allow a stain to penetrate evenly across all parts of the bow.
I always like to glue up both contact surfaces. I also make a habit of leaving both glued surfaces to soak up some glue before positioning the two surfaces together for clamping. I believe this “sizing up” habit allows more time for the freshly exposed wood cells to suck up more glue. In fact, with wood that has been dried down to below 10% moisture content, it is often the case that more glue needs to be added after 5 minutes of sizing up. This is because much of the glue will now have been sucked up into the wood emphasising the need for an additional application of glue before placing the overlay in situ ready for clamping.
The third consideration to be made in order to create the strongest bond possible is the method of clamping used to press the glued surfaces together.
I find that if I apply significant compression to an overlay immediately after gluing up, all that happens is the overlay slips off the tip. To avoid this from happening, I only use slight pressure from a spring grip type clamp for the first 10 – 15 minutes of drying. This allows the glue to soak as deep as possible into the wood and start to grip the overlay into position. By doing this you will stop the overlay from simply slipping off the stave tip when the compression is increased to full pressure.
After 10-15 minutes I remove the spring clamp and insert the bow tip carrying the overlay into the jaws of my vice. From here I can crank up the pressure to make sure that the bond is really good and strong. The pressure which can be exerted from the vice will ensure that no gapes appear at the joint line.
Be sensible with the amount of pressure applied to the overlay/bow tip and use something reasonably soft as a packing material to protect the bow tip and the overlay from damage from the metal jaws of the vice. I use scraps of leather for this purpose.
I’ve never had an overlay come off when the join has been prepared, glued and clamped it the manner described above. The same can’t be said for the common practice of using superglue and a spring clamp!
After at least 6 hours of drying time, you should now be able to finalise the shape and profile of your tip overlays. Before you grab your tools and start working on the final appearance of you bow tips and overlays, take the time to ensure that the strength of your overlays will not be compromised by their final design.
The maintenance of strength needs to be given priority. A broken tip overlay is a significant repair at best, a broken bow at worst. Very fine bow tips are very popular these days but as tempting as it may be to reduce the width of your tip overlays to the bare minimum, antler is quite brittle and can snap under load if reduced too much.
An overstressed antler tip overlay will typically break at the string groove. To mitigate against this, I like to leave at least 5mm of material in the string groove. In order to achieve this, I find that an antler tip overlay needs to be at least 7/16th” wide and 3/8th”thick. I also like to leave the bottom overlay bluntly tipped because the bottom tip is always more likely to get knocked than the top tip.
Whilst you could leave your overlays much wider and thicker than this, by leaving excessive material at the tips you will be leaving unnecessary mass in the very tips of your bow. This additional mass will affect the performance of your bow albeit in a very subtle way. If maximising speed and minimising hand shock is important to you then aim to achieve a final shape and profile which reduces mass to a minimum whilst preserving strength.
Beauty is in the eye of the beholder. That said, long thin antler tip overlays are very easy on the eye. Especially if a suitable amount of antler colour and pearling has been retained during the shaping process. Play with a few different shapes and profiles and see what works for you.
Note that I will often leave both tip overlays oversized until after tillering is complete. Then I will refine the shape and profile to suit my overall bow design and appearance.
I like quite fine tips on willow leaf shaped limbs. These overlays are on a bow with some character. Since these particular limb tips are angled out due to the naturally curved out limbs, it was necessary to carry the string groove around the sides of the overlay to ensure that the string did not slip off the sides. This can happen on crooked limb tips which only have a groove cut across the face of the overlay.
So to recap, before you embark on your next antler tip overlay project, be sure to take the time to:
Select the right type of antler first. Then make the effort to achieve the basic shape and profile of your tip overlays BEFORE you glue them on. Work through the steps necessary to create the strongest bond possible. And finally finish your overlays in a way which is guaranteed to maximise strength, minimise mass, whilst emphasising the beauty of this magnificent natural material.
Deer antler is a material which has been used by man in primitive arts and crafts for many thousands of years. In fact, deer antler has been used both as a raw material, and as a tool, to make all kinds of primitive artefacts.
Deer antler is a versatile material. It has qualities which lend itself to promoting its use in the construction of tools and equipment. And as far as primitive archery equipment is concerned, antler adds both functionality and aesthetics to bows, arrows and many other associated items.
Personally, I love using deer antler as a natural material for building primitive archery equipment. And by using an authentic raw material such as antler, we primitive crafters are very much in keeping with tradition.
Deer antler presents an element of symbolism too. Antler is a well-recognised representation of nature. Deer are truly wild and majestic creatures, honoured throughout time, and respected by hunters the world over.
It is certainly fair to say that our primitive archery ancestors (as well as many contemporary archery hunters for that matter) pursued deer as a prized and challenging target species. It therefore seems appropriate to adorn a primitive bow (or even a modern traditional bow) with a functionality promoting, and decorative material sourced from one of the very creatures which inspired man’s most notable primitive hunting innovation – archery.
But before you race out to incorporate deer antler into your next primitive archery build, there are some things you must first consider. As with all materials, deer antler has some pros and some cons. Before committing to using antler as your material of choice, first you should be aware of what antler does well and what is does not do well.
This article discusses 13 things you should first know before embarking on a project using deer antler. First, we will discuss the upsides!
Pros:
1 – Antler is easy to source: Deer antler is easily available. It can be readily purchased in pet shops as dog chews, and it can also be bought online and at game/countryside fairs etc. Ebay has any amount of deer antler available throughout the year so getting hold of some should not be a challenge. I also stock and sell a wide variety of different sizes, shapes and colours of antler so if you’re in the UK, give me a shout via the contacts page if you would like to discuss your antler needs with me.
2 –Antler is easily worked with wood working tools: Deer antler is soft enough to be worked with high carbon tool steel, which is what most rasps, files and saws are made from. Common abrasives such as sandpaper, wire wool etc also work well as a means to finish antler. This means that you won’t need to buy extra tools, materials or equipment to work with antler. You will find that you will get by perfectly well using many of the tools that you already have for general woodworking. The only exceptions being bladed tools such as knifes, chisels drawknives and axes which will dull very quickly if used on antler.
3 – Antler is aesthetically pleasing: I think deer antler is beautiful. It’s just plain nice to look at. It also has that wild rustic appeal to it which aids in generating the character that primitive bows are renowned for.
The contrast in colour between the browns and creams of the antler stand out from typical wood colours making it an ideal decoration for bows. Wooden bow tip and riser overlays made from deer antler look amazing!
4 – Antler is hard enough to avoid string wear: Antler is harder than wood and therefore does not suffer from bow string wear. This is another reason why deer antler makes a great material to make bow tip overlays from. For the same reason, antler also makes for a good choice as an arrow rest or as a material for an inlayed arrow pass.
5 – Antler works well with most glue: Antler is usually added to a work piece with a glue being used as the binding agent. Antler can be stuck to other natural material such as wood and sinew very easily using regular wood glue, epoxy and superglue. My favourite glue to bond antler to wood and sinew is Titebond III.
6 – Antler is weakly porous: There have been times when I have wanted to stain a bow which has antler components built into the design, but I’ve not wanted the antler parts to take on the stain intended to alter the colour of the adjacent wood. Finely sanded and polished antler is only very weakly porous. This means that it does not readily take up a stain into its surface. This makes it easy to remove stain from polished antler. If I get stain on a tip overlay for example, I simply wipe the stain off with some kitchen towel dipped into acetone. This will bring the antler right back to its natural colour state.
7 – Antler is strong in compression: Tribes from various parts of the world have used antler as the main structure of their bows for millennia. These bows were either backed with a heavy sinew application or they were supported in tension with sinew cabling. Our ancestors knew that the compression strength of antler was effective at creating an efficient and effective bow belly.
Cons:
8 – Antler can be expensive to buy: Depending on where you source it, it can be costly to stock up on some decent antler. I frequently see antler being offered for sale in pet shops and on the internet for silly money. Ebay will likely be the cheapest place to buy antler. Country fairs often have buckets full of antler on sale priced per piece for reasonable prices too.
If you have a particular use in mind for a piece of antler, then you really should lay your hands on a few different bits first so that you can be sure that the bit you choose will serve the intended purpose before you part with your cash. At least a bucket full of antler gives you a chance to pick out the bit that suits your purpose best.
I sell premium quality antler on a piece-by-piece basis for a very reasonable price. If you would like to buy some then contact me through my contact page to discuss your particular requirements.
9- Antler can vary considerably in its appearance from one piece to the next: The external structure of the antler, in combination with the vegetation type of the area inhabited by the deer, dictates the colour of the antler. This is why some antler is darker than other pieces, especially when antler is compared to other antler belonging to animals which live in completely different areas.
The time of year which the antler departed from the deer will also influence the amount of staining and subsequently, the colour of the antler. Male deer grow a new set of antlers each year. This new antler growth occurs under a thin membranous tissue called velvet. Once their antlers are fully grown the velvet covering dies. As the dying velvet peels away from the hard antler beneath, the exposed antler is white in colour with a structure and appearance of bone.
As the season progresses the deer clean off the rest of this dead velvet by “fraying” their antlers against vegetation in their surrounding area. This “fraying” activity is what colours up their antlers. If male deer didn’t fray vegetation, then their antlers would stay white.
The dark brown colour that you see on antlers is from the sap and dirt from countless fraying sessions. So, with this is mind, the vegetation type in the locality of the deer will influence the colour and the darkness of deer antler. And if a piece of antler was removed from a deer shortly after cleaning of its velvet, then the antler may not have had much time to be coloured up through fraying.
Antlers acquired early in the season will be much lighter in colour than antlers taken from deer late in the season. Especially after the rutting period which is when deer spend vast amounts of time scrapping their antlers against anything and everything!
10 – Not all parts of the antler can be useful for certain jobs: The appearance and usability of a piece of antler will depend to a large extent on the species of deer which it came from and the age of that animal. Remember that male deer grow a brand-new set of antlers each year. A young male deer will only grow a small set of antlers for the first couple of years of its life. Older animals will generally have larger antlers up until a deer gets too old in which case their antlers begin to reduce in size with each passing year. This old aging process is referred to as “going back”. Big antler therefore comes from mature but not old male deer.
If you take an antler and saw it in half lengthways, you will notice that the main beam was significantly honeycombed on the inside. Back down towards the coronets however is far more solid.
The honeycombed section is no good for tip overlays or arrow rests as the porous parts are much weaker than the solid parts. These porous areas will crush under compression. If you are planning on making your bow tip overlays or arrow rest from antler, then use the solid section down at the very bottom of the antler by the coronet.
11- Antler does not take up stains/colours well: If you actually wanted to stain your antler a darker or different colour, then you will find that most regular stains will not impart and significant change to the appearance of antler. The outside of antler is not permeable so will not allow a stain to soak in deep enough to have any real affect. Anything that you apply to antler will merely remain on the surface so will likely wipe off if you apply a solvent type of sealer to finish your project.
12- Antler is weak in tension: Antler will break when exposed to tension forces unless it is supported by a strongly elastic material like sinew. This is why bows with limbs made from antler were backed with sinew, either glued on in layers as is conventionally done, or by supporting the back of the bow with sinew cabling as done by the likes of Eskimo and Inuit people.
13- Poor flexibility can make antler behave brittle: Don’t expect antler to bend much on its own. Bending forces along the tension plane can cause antler to snap, especially if the solid outer surface of the antler has been compromised through working with tools.
A classic example of this tendency to break is sometimes witnessed on bow tip overlays. The break happens where the string groove has been filed into the overlay and the usual cause of the break is a heavy impact on the tip of the overlay caused by a bow being dropped.
Another cause of tip overlays breaking at the string groove is as a result of using overlays which are very long and are fixed to a working section of the bow limb tip. The bending of the tip presents a bending force to the overlay which results in a break at the weakest point which is always at the string groove. Static tips prevent this issue.
So, there you have it. Now that you are aware of some of the main benefits and pitfalls of using deer antler, see if it’s time to incorporated antler into your next primitive archery project!
