Sinew and snake skin backed Heavy Yew Flat bow 68#@28″ (Bow No: 23)

This bow was built from a Yew stave which I salvaged from a pile of yew logs cut down by tree surgeons a few years ago. If I’d know in advance that this particular yew tree was scheduled for felling, then I’d have kindly asked the tree surgeons to have left the better logs long and scar free. But unfortunately I got there too late and they had butchered most of the nice clean limbs.

After wiping away the tears and a bit of searching through the carnage I was able to recover was the one stave that was used in this build. Thankfully this one stave was pretty decent. It was almost clean across one face and fairly straight viewed face on. Side on however was a bit less straight.

The stave measured 70″ long and viewed from the side, right smack in the middle was some deflex to the tune of around about an inch and a half overall negative tip to tip. There was a good chance that steam bending could pull that deflex out of the handle but I figured it would be fine left alone so long as the outer thirds of the limbs were flicked a little to compensate for the natural deflex positioned in what would be the handle in the finished bow.

So after taking the bark off and chasing off a few rings of sapwood, I reduced the edges and the belly material enough so that I could heat some reflex into the last 10 inches of the limbs outer thirds. This added reflex was able to bring the overall deflex to reflex ration back to a level playing field. Which is always where I prefer to start from.

After a good bit of cooling off time I roughed out the face profile so I could inspect the string alignment and was pleased to see that there was no need for any other heat corrections. And after a bit of whitling here and there I was happy with the overall shape and size of the bow.

Given the shear amount of material I had to work with on this stave, I felt confident in being able to produce a bow which would be a bit heavier than what I usually aim for. And given that I intended to sell this bow, I wanted to maximise it’s longevity, durability and performance by sinew backing it thus increasing its potential draw weight even further.

After sinew backing and a 6 month curing process I finished this bow and shot it in over a couple of weeks. The 1/4″ positive tiller held good and she performed with great power and cast. Over the chrono she consistently recorded arrow speeds of around 165 fps with a 550 grain arrow. And with no noticeable hand shock or kick, she was a pleaser to shoot in, despite the heavier than personally preferred draw weight of 65lbs.

To finish and decorate I covered the bland sinew backing with two King Rat Snake skins embellished with some earth pigment edge work to make the transition from wood to snake skin pop. Tip overlays of red deer antler were fitted and the top nock was cut to receive a stringer since this bow was a little too heavy to safely string via push pull or step through method.

The handle covering/arrow pass is all wild red deer bark tanned leather and the finish is Danish oil buffed and polished with paste wax. For a string she was fitted with a custom built 12 strand B50 flemish twist string fitted with wild fox fur silencers to make this already quiet bow whisper quiet.
