After a fun few hours chasing after some squirrels with the airgun and the hound the other day, it dawned on me that a squirrel’s tail might just make for a useful and rustic looking bow string silencer.
I’ve made god knows how many string silencers before, usually from rabbit or fox (my personal favourite) fur but have never thought to give squirrel tails a go.
From time to time I will egg tan a pelt just for use as string silencers. A properly egg tanned, softened and smoked rabbit or fox pelt lends itself perfectly to being cut into nice soft thin strips of fur which can be wrapped around a bow string to produce great authentic looking string silencers which function very well.
But the truth is, in terms of performance, you don’t actually need fully tanned and softened pelts to make simple and effective string silencers. You can just wrap a piece of raw pelt around your bow string and let it dry in situ.
In fact, without laying your hands on them, most people would not be able to tell the difference between a properly tanned piece of pelt and a raw fur pelt strip which has simply been wrapped and left to dry thoroughly on your bow string.
So interested primarily in what a squirrel tail silencer would look like, I decided to skin off a squirrel tail, split it down the middle and wrap it in its raw albeit dried state around a bow string to see what it looked/functioned like.
Here is a description of how I went about the experiment and what the end result looked like:
For this project you will need a sharp knife, cut resistant gloves and a squirrel (preferably a dead one like this guy!)
Start by making an incision at the base of the tail. Only cut deep enough to cut through the skin. Try to refrain from cutting through the deeper tail muscles as you will weaken the tail to a point where it could rip it completely off when you come to pull the skin away from the bone in a minute.
Once you have cut through the tail skin all the way around, start to pull the skin down towards the tip of the tail. Try and work around the whole tail so that you can see the underlying muscles all the way around.
Now work the skin back about an inch. Then take your thumb nail and press down against the roll of skin that you have formed so that the force imposed by your thumb is directed down towards the end of the tail. At the same time, start to gently pull your hand which is gripping the skin down and away from the base of the tail.
You should start to feel the skin slip away from the bone and muscle within the tube of skin. Make sure that you pull hard enough to pull the skin away, but don’t pull so hard that you rip the whole tail off the body.
The tail skin should just slip right off the end of the bone/muscle like pulling a sock off.
Now stretch out your skin tube and lay it down on your work surface so that the widest two faces of the fur/skin tube are facing downwards and upwards. You want to cut your skin tube in half by making the first incision along the widest face which is now facing upwards. I do this by inserting the tip of my knife into the opening and making a slit from one end all the way to the tip of the tail.
Push the blade into the opening as far as possible and slit the skin tube right down the middle.
Take your time to make sure that you are keeping to the centre line so that your strips end up equal in width.
Once you have split the skin tube right down the middle you can lay the skin out flat and straight ready for the next cut.
Now find the centre of your skin and with a rolling, slicing and pressing motion, cut straight down the middle of your tail skin.
You should be left with two strips of raw tail skin with hair still attached. Trim off the base end a bit to remove the widest piece of skin and the adjoining short hair. This section with short hair is of no use to us.
Give the two strips a good wash with soap and water to clean them up a bit.
Now rinse them off and hang them out to dry somewhere that will stay dry and warm. I hung my two strips above my wood burner and they were completely dry after just one night. The next day I gave the dried skin strips a bit of gentle manipulation with just my fingers in order to soften the stiff, dry skin a little.
I then fitted them to a new bow string the same way I would fit any pelt strip string silencer. After securing one end of the skin strip to the slack bow string by parting the string and threading the end through the gap.
I then re-apply tension to the bow string and begin to wrap the rest of the skin strip around the bow string in the same direction as the bow string has been twisted up.
Once I’m only left with 3/8 inch or so of the skin strip, I will take the tension out of the string again and part the string so that I can pass the tag end of the skin strip through the gap I’ve created, securing it in place once the string tension is re-applied.
At this point I will typically push the two end of the skin strip towards each other with hand pressure. This causes the skin strip to bunch up nicely which in turn helps to flair out the hair more evenly.
If need be, the last thing to do now that the string is taught again is to trim off any tag ends of the skin with a pair of scissors.
I think they look pretty cool and they seem to hold up to the wear and tear as well as any other pelt strip silencers. The only criticism I have is that they do look a little dishevelled the moment they receive a soaking. But then don’t most fur silencers!?
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.
Here she is. Enjoy!

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!
This bow started out life as a very simple 60lb flatbow which was made from a stave which had been given to me by my neighbour who was grubbing out a patch of wasteland on his farm. Whilst the log was fairly straight (for Elder) the twist was the best part of 80 degrees!
I almost binned the log but thought that I’d use it to test how well a roughed out green Elder stave could be trained to conform to a better shape by using a form and clamps throughout the initial air drying phase.
After a few weeks on the drying form the clamps were removed to reveal a nice straight and twist free stave which I moved indoors to hang above the wood burner to speed dry for another couple of weeks.
A one inch long drying check behind one of the larger knot clusters was the only fault which I was a bit surprise by since Elder can check quite badly when force dried too hard.
Elder is strong in compression so I felt safe in keeping the limb width down to around 1″ 3/8ths. I’d never do this for a wood like Ash or Hazel but Elder is a fantastically springy wood which can cope with way more of a narrow limb profile so long as the length is not compromised too much.
I kept the length long at 66″ nock to nock and opted for a straight rigid handle and simple self nocks. I tillered the bow to 60lbs at 28″ and shot this bow like that for about a year. She performed well and was a powerful fast and efficient bow but 60lbs was too heavy for my likings so back in the late autumn of last year I decided to either get rid of this bow or drop the weight.
At around the same time my brother’s eldest son was asking if I could make him a bow. Whilst happy to oblige, (great excuse to make another bow) the reality was that I was short of time so instead of making him a bow from scratch I opted to re-tiller this Elder bow for him.
Long story short, I dropped the weight down to a more comfortable draw weight for my nephew at his draw length which is 26″. And instead of just removing wood from the previously flat belly I decided to hollow out the limbs to match the crown on the back by using the curved scrapper to re-tiller.
The bow had taken about an inch of set whilst in its previous 60lb straight limbed flat bellied form, so after reducing the weight I decided to see if I could reduce that set a little by heat treating the belly whilst fixed to a slightly reflexed form.
But before heat treating the limbs I also decided to lightly flick the tips to try and reduce the stack which it had suffered a little from previously. The recurved tips where steamed in, then once they had settled, I heated the recurves a bit more thoroughly with the stove top in order to ensure that they would never pull out.
After heat treating the flicked tips and the hollowed out limbs I finished the re-tillering and quit at 42lb at 26″ with a 1/8″ inch positive tiller. Shooting in and re-sanding shaved off another couple of pounds so I finally ended up at 40lbs at 26″.
The previous finish on this bow had been urethane varnish which I was keen to strip of so I could stain the revamped bow a darker colour. After stripping I hit the bare wood with a dark Jacobean oil based stain then sealed her up with 8 coats of Truoil.
A simple leather handle cover and piece of leather as the arrow pass finished the job. The bow is now a light in the hand (460grams) snappy and pointable bow and my nephew was delighted the the end result. I’ve paired this bow up with some 35-40 spine arrows and she is sending a 400 grain arrow over the chronograph at an average of 141ft sec which isn’t anything special but sure is fun to point at stumps!
Here are the pics. Hope you like!

Draw to 26″
1/2″ of set immediately after unstringing. Returns to 1/8th inch after resting.
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.
The stave for this bow came from a 4” diameter Ash tree which produced two staves. One stave was pretty straight and featureless and I used that stave to make a plain but functional rawhide backed recurved flatbow for a friend of mine. The other stave had a nice bit of wiggle in one half and a few other little features so I decided to use it to make this unbacked character flatbow.
The tree was felled back in the late summer of 2022 so it had a bit of cambium left on after taking the bark off. I roughed the stave out whilst totally green and force dried it on a slightly reflexed form in order to fix some slight tip/handle misalignment. The form also evened out some slight but uneven and mixed deflex/reflex in both limbs and corrected the very small amount of limb twist which was apparent in the bottom limb.
After a month of drying whilst clamped to the form positioned indoors on my sun baked windowsill, I was left with a nicely aligned stave with an inch of evenly distributed reflex and just the right amount of wiggle left to make this flatbow worthy of the title “character bow”.
The small to moderate crown on this stave was worth considering. I find that a higher than average crown on tension strong woods like ash can sometimes be advantageous. As I’m sure many bowyers will attest to, Ash wood bows are quite susceptible to compression fractures on the belly. This is because Ash is far stronger in tension than in compression.
The small to moderate crown on this stave could allow most of the back of this bow to work in tension. Too much tension could chrysal the belly if not considered carefully in the design process. A high crown would allow less of the backs width to work in tension therefore reducing the crushing force imposed on the fairly flat belly.
Bearing in mind that the growth rings on this stave were a bit on the thin side, and that the early wood in the growth rings made up a reasonable amount of the bows volume, I decided to round the corners on the back quite heavily in order to create an artificial high crown and reduce the tension strength of the bows back.
I’ve used this little trick many times before to help protect the bellies of bows made from compression weak woods such as Ash, Hazel and Elm which are all very strong in tension. The result is a D shaped limb cross section with the curved portion of the D representing the bows back and the flat portion of the D representing the bows belly. The complete opposite to a classic English Longbow design which works very well with high quality Yew.
The down side to this approach is that much of the edge wood is taken out of commission. The up side however is that the full width of the flat belly is still able to function by providing compression resistance which will oppose the crushing forces of the tension strong back as the belly relates to the now tension weakened artificial high crown.
The artificial high crown imposed in the design of this bow worked well at preventing fretting on the belly, as did additional mitigation measures such as forgoing recurves, minimising the length of the stiff handle section, and maintaining adequate limb length and width. For this reason the bow was kept long at 66” nock to nock and has 1″ 15/16 wide limbs for the first two thirds of the working sections. The riser section is approx 10” long including 3″ fades and is stiff.
Previous experience of Ash staves from this particular area have reinforced the idea that extra precautions need to be taken to avoid excessive tension forces on staves like these which clearly have limited compression strength. For this reason I opted to keep the weight down to 50lb at 26″ or less which is around my favourite draw weight anyway. Much heavier than this and fretting might occur without increasing limb width or length, which I couldn’t really do with this stave anyway given the dimensions I had to work with.
The bow was very easy to tiller, even with the wiggle in the first third of the top limb. The tiller is elliptical ¼” positive and shoots well with split fingers with both limbs timing together very well. When unstrung after shooting a few rounds this bow shows about half an inch of sett which quickly returns to dead straight after resting.
Since the bow was for me to use I opted for simple but small self nocks. If I’d built it for someone else then I’d probably have put overlays on it. The arrow shelf was a last minute addition whilst contemplating the final handle design.
I like to shoot of the knuckle personally but figured my wife might shoot it so I used the significant width of the staves handle section to produce an arrow shelf which is certainly not cut to centre, but is not far from being in perfect alignment with the string which clearly favours the left side of the riser. This bow isn’t very arrow fussy but definitely favours an arrow in the 45-55# range.
The lightly fluted 3” fades were an afterthought and were an attempt to create a little more feature to the otherwise plain bottom limb. In hind sight this was a risky manoeuvre on a timber like Ash which is very prone to delaminating between the growth rings at the fades. That said, so far so good. No sign of any splitting yet and I’ve been shooting this bow quite a lot.
The finish on this bow is an oil based dark oak stain followed by many coats of Trueoil. The small amount of cambium left on the back picked up the stain differently to the exposed wood on the back which created a nice camo effect. This particular stain really grabs hold of the grain on Ash and produces a beautiful high definition wood grain on the belly.
The handle is contoured to my favourite grip pattern and is covered with a scrap of leather from an old jacket which I rubbed some earth pigments into in order to produce a more mat/antique appearance. The arrow pass is covered in the same leather only rough side up.
This bow shoots well. Not the fastest longbow by any stretch (450gn arrow at 27” 148ft/sec) but nice and comfortable to hold back at full draw without stacking much if at all. No hand shock due to the balanced tiller, comfortable grip and moderate tip mass.
I really like this bow and it has been my favourite stump shooting bow throughout the autumn of 2022. That said I have loads more just like it and might have to find a new home for it since I’m fast running out of space for more bows. Well, at least that’s what the wife keeps telling me! If you like the look of this bow then keep an eye out on Ebay as it might end up being listed there some time after Christmas. If I do list it then I’ll edit in a link to the listing at the top of this post.
Here are the pics:

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 green Field Maple stave roughed out and clamped to a reflexed form to try and produce a more workable shape. Note how the tips have been left full width for extra sideways leverage from the clamps. this really helps to pull twist out.
Side view of the green stave being force dried in the mid day sun on an especially hot late summer day. Note the remaining reflex in the handle section.
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.
Plenty of character left but a much more workable shape overall
side view immediately after removing the clamps and form.
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.
Marking out the limb tips. I’d decided to plan for fine antler tip overlays on this bow so initially I laid the rough tip design out to 20mm tapering out to full width at mid limb.
Marking out the rough outer limb shape using my steel ruler to follow the natural curves of this stave. The final shape however will be dictated by the grain itself rather than by lines.
Working down to my lines with the draw knife. Field Maple is a wonderful wood to use cutting tools on.
The approximate shape of the bottom limb. I decided to go for a classic willow leaf shape and carry the tapper from mid limb out to the tips. This stave was initially roughed out to 2 ¼” wide which is what the stave measures in this picture. I may reduce this width to 2” before tillering though.
Top limb roughed out to the same approximate dimensions as the bottom limb. The top limb will be the straighter of the two limbs.
The string alignment appears to be favouring the left side of this picture which suits the decision to make the nearest limb the top limb. This will result in the arrow favouring the left hand side of the bow which suits me as a right handed archer.
Now to reduce the limb thickness to something more like 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.
Working down to my lines with the draw knife.One edge worked down to the line.
Same on the other side.
Bringing both sides together to make the limb initially flat on the belly.
There are only a couple of knots on this stave which look like they will fall of the bow as more material gets removed.
This limb is now approximately 14mm thick as it leaves the fades tappering down to 10mm thick at the tips.
5 minutes with the Shinto rasp makes sure everything is nice and flat with an even thickness taper. I like the Shinto rasp for this job because it is easy to keep flat. Whilst it’s great for working down flat sections, it won’t get into dips etc very well.
Following the dips and humps on the belly to make sure the edge thickness is even. The half round rasp comes in handy here.
A quick scrap with the card scrapper and the basic limb thickness is ready for finer scrutiny.
A nice bit of wiggle to work with.
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.
Next I needed to get the cambium off the back of the stave.
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.
The valleys and troughs on the back require the use of a gouge to get down through the cambium to wood.The curved scrapper is used to expose the first layer of wood.
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.
The curved scrapper can get into most of the valleys and troughs and can be useful for working around raised spots like knots too.
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.
A small gouge comes in handy at times.
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.
Here is an example of where there is a hill on the back creating a thick spot. I’ll counter for this by scraping away material on the belly which is directly opposite the high point on the back.
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.
I use my fingers and thumbs to feel for differences in thickness. Once I’ve found a thick spot then the curved scraper gets called into action.Constantly checking for even thickness.Trying to mirror the back on the belly.
Here you can see than I’ve dug out a trough on one side of the limbs belly to replicate what is happening to the surface wood directly opposite on the back of the stave.
Here the limb has a notable crown so the whole width of the belly is hollowed out to compensate.
This limb has a 12” section which has a high crown so the belly here will have a correspondingly hollow profile. Maple is a wonderful wood to work with a scrapper.
Countering the excessive reflex in the handle with some deflex in the limbs.
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.
Here I’m using a heat gun to gently heat up the belly. I make sure I heat both sides of the clamp to make sure the deflex is evenly distributed throughout the first two thirds of the limb.
After about 10 minutes of heating the belly and the sides I then leave it to cool for an hour.
After both limbs have totally cooled I check both limbs for twist. Both limbs could do with a little bit of a correction so I fit a scrap piece of wood to each limb so that I can lever the limbs into a better position.
Once again the heat gun is used to heat the sections of the limbs which I want to correct
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.
Now that the limb twist has been dealt with I steam the tips for half an hour so than I can put a small amount of reflex into them.
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.
Into the recurve form she goes. My oven door handles act as the perfect brace to hold the stave in position whilst left to cool for half an hour.The flat wooden spatula which you can see stuffed into the tip acts as a wedge to hold both the limb tip and the steel ruler in place. The old tea towel just prevents the back of the limb tip getting marked by the form. This is how I do most of my recurves/flicked tips.Both tips flicked.After a rest overnight to cool and re aclimatise the stave is now looking quite nice and even from the side profile.
The tips are both kicking out in opposite directions which will call for a little more heat twisting in order to get them lined up.
I’m keeping any further adjustments away from the tips so as not to cause the recurves to fall out. I will give both limbs a bit of a twist with the heat gun then recheck for tip alignment and string alignment overall.
By griping the upper third of the limb in the padded jaws of my vice and fitting the other limb with a wooden paddle I can lever a significant amount of counter twist into the mid limb section.
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.
Now would be a good time to roughly shape the handle.
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.
Working down to my lines with the draw knife first.Hitting my lines accurately and achieving handle symmetry with the Shinto rasp.

Rounding the corners on the back. I sometimes like a spokeshave for this job.Cleaning up the corners and the sides and making sure the face profile is finalised before tillering starts. Next job – tip overlays!
Bottom nock with string groove cut. Both overlays are left wide for now and will be thinned down quite a bit before the bow is finished. I like quite fine tips on willow leaf shaped limbs.
I’m heat treating both flicked tips here in order to prevent the bend pulling out once tillering begins. I also quite like the dark coloured tips which results from only targeting the last 6” of the limb. The dark colour contrasts nicely with the lighter untreated belly wood.Now that the overlays are functional I can eyeball the tips and handle for alignment. The string biased towards the left side of the bow appears a little too strong so I decide to heat the handle area for a correction.The handle is quite thick so I opt for setting the stave over the wood burner top whilst fitted to a bending jig.
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.
Roughly shaping the handle before starting the tillering process.Deflex reflex staves are always easier to tiller as the even shape has already been achieved through the various heat bending processes.
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.
Bow unstrung after tillering to 53lb @ 26″
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.
A scrap piece of buckskin leather will do for now.
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.
Happy with the final tiller it’s time to finish this bow. I start with 120 grit followed by 200 grit followed by 000 wire wool.Next I wet the whole bow down with plain water to raise the grain.After a day to dry thoroughly the grain gets hit back down with 000 wire wool.Then its on with an oil based stain and many coats of Truoil to finish.
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.
For this tip overlay project I’ve decided to use red deer antler. The piece on the left is the coronet end from a yearling red stag and is perfect. The piece on the right is cut from the middle of an antler and has the typical hollow, porous appearance. I’ll be using the piece on the left.
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!
This antler has some nice features which, with care and planning, could be carried over into the final appearance of the tip overlays.
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.
The pithy middles of the pieces in this picture is minimal and will be ground away as the profile is finalised leaving behind solid antler for maximum overlay strength. By prioritising the removal of material from the back of the overlay I will be able to retain as much character from the upper surface as possible.Here I’m using my Shinto rasp to flatten the sides of my overlay pieces so that they are easier to grip in the vice. By doing this first I will be able to secure each overlay well enough to rasp away the undesirable portions of material whilst retaining and incorporating the desirable features into the final design.Rasps are useful tools when it comes to shaping antler. Rasps remove material fast and efficiently so are ideal tools for achieving the basic shape and profile requirements.Basic face width ready to be reduced into the basic shape and profile.Now that I can grip the pieces in the vice, I can work on using my rasps to shape the basic top profile. I want to retain some of the colour and pearling whilst at the same time achieving an efficient design.By mounting the Shinto rasp in the vice, I can grind the antler pieces against the cutting face and shape the face of the overlay with ease. This method helps keep everything nice and flat.Basic rounded top profile achieved. Note how I have retained enough of the dark brown colour to contrast beautifully against the ivory cream colour of the exposed underlying internal antler material.Now I’m switching my attention to the back side of the overlay. This is where the bulk of the waste material will be removed from. This will facilitate the creation of the classic wedge-shaped taper which enables a beautiful, natural and functional transition from the overlay to the back of the bow.
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.
Here I have gripped the top end of the overlay piece in the vice so that I can rasp away at the underside of the overlay to produce the basic wedge shape. I have pushed a scrapper in underneath the bottom end of the overlay in order to stop it from getting pushed down into the jaws of the vice as I apply top-down pressure from the rasp.Here I am finalising the wedge shape and thickness. By simply dragging the overlay towards me across the fine face on the Shinto rasp I can rapidly remove excess material from the underside of the overlay piece. Used this way the Shinto rasp is a great tool for creating a perfectly flat base. This makes matching the overlay to the back of the bow tip much easier later on.A final functional wedge shape has been achieved whilst retaining maximum aesthetic appeal. Notice how the small amount of porous pith that was previously visible has now gone. I’m now just left with solid antler which will maximise the strength of the overlay. If I’d chosen a piece of antler from further up the antler then the pithy middle would still remain a considerable part of the overlay and would therefore compromise the structural integrity of the overlay once the string groove was cut in. The retention of the pith would likely result in a break at the string groove at some point in the future.A view from on top. You can see that this overlay has been left much wider than it needs to be. This excessive temporary width is helpful at this stage and throughout the gluing stage. The final width can easily be achieved once the overlay is secured in position.
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.
Creating a flat surface on the limb tip to optimise the fit between the overlay and the back of the bow tip.
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.
Once the rasp has levelled the tip and the overlay has been tested for fit, sand out any tool marks so that you do not have to try and removed tool marks after the overlay has been fitted.Once both surfaces are matched up perfectly and all the tool marks have been sanded out of the back of the bow tip, don’t waste any time getting you overlays glued up and clamped.
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.
Stave tips ready for sizing up with TBIII.
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.
TBIII applied liberally but only on the contact areas.
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.
Making sure the excess glue is wiped off whilst it is still wet. I use a wet piece of kitchen towel for this.
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.
Here is the bow tip with the glued-up overlay in situ, set in the vice to cure under pressure. I leave it set up like this in the vice overnight.
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.
After a night to dry I work the tips down to a basic profile with rasps, files and 80 grit sandpaper. The top tip will be pointed and the bottom tip will have a slightly more blunted appearance as a hedge against knocks.Filing out the rasp marks once the basic shape has been achieved.

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 use a tile saw to cut the initial tillering string groove on antler tip overlays as it removes material fast and accurately. Once tillering is completed, I’ll finish off the string grooves with a chainsaw file and sandpaper.
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.

This design is simply to minimise the effects of a potential impact with the ground.Bottom limb tip overlay viewed from the side.Top limb tip overlay. Since this overlay will be less likely to impact with the ground etc I’ve gone for the more typical pointed profile.Top Limb tip overlay viewed from the side.
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.
