Sinew Backed Yew Holmegaard 70#@28″ (bow no. 17)

Back in the spring I was contacted by a friend of a guy who had purchased the character yew flatty I blogged about here: Primitive Character Yew Flat bow 52#@28” (Bow no. 14) – Southmoor Bows which he had bought through the Southmoor Bows ETSY shop. This guys friend really liked that particular bow, so he got in touch with me to ask if I could build him something with a primitive vibe, but a bit heavier, as this chap came from a ELB background and was accustomed to shooting bows in the 65lb plus bracket.

After a bit of discussion we settled on a plan. I had in my possession a rather nice and character laden Yew branch sucker stave, which I could easily envisage being turned into a Holmegaard type longbow. This stave measured 71″ so was both long/wide and clean enough to produce a heavier draw weight bow built in a classic Holmegaard/pyramidal/flatbow type design, as opposed to something more like an ELB, which is a widely accepted design, recognised as being well suited to bows intended for higher draw weights.

We’d settled on a target draw weight of somewhere around the 65-75lb mark, so I had to now figure out how I could optimise the bows design and features to encompass the heavier than average draw weight, as well as all the wonderful characteristics of this particular stave.

Rather than go full on Holmegaard and get all anal about precise authentic dimensions, I decided to let the stave dictate the overal profile. And to ensure long term durability I opted to incorporate a robust application of sinew backing to minimise both potential set, and vulnerability to wear and tear over time.

So my plan was to build a straight limbed pyramidal profiled long bow with semi lever like needles for tips, and a completely static handle section. The bow would end up 70″ nock to nock and have 8″ static tips. These none bending tips, combined with a 4.5″ stiff handle with 3″ long flowing fades, would leave me with just about 43.5″ of working limbs. Since this wasn’t a massive amount of moving wood, I decided to lay the bow out asymmetrically so as to give the bottom limb a bit more support over the long term.

The intention was to maintain the original crowned shape of the back, whilst adopting a rounded D shaped belly cross section throughout the fades and working sections of the limbs. The tips would transition in cross section from D shaped to ridged to reduce mass whilst remaining static. The handle would remain deep and relatively straight with no shelf as the chap who asked me to build this bow was a fan of shooting off the knuckle.

The stave had no overall natural reflex or deflex, but the 6 sets of branch whirls which were evenly distributed between both limbs did have some contour, thus giving the false impression of deflex where the grain flowed around the knot whirls. These flowing lines would need to be incorporated into the final profile of the bow as my intension was not to interfere with the natural shape of the staves side profile. Fortunately, this particular stave was completely absent of any twist or snake, so other than working around the knotty branch whirls, laying out the intended profile was, for once, a doddle!

The Heartwood/sapwood ration was about right too, with this stave having no more than 1/4″ of sapwood under the bark. Subsequently, I only had to get the bark off in order to expose what would end up being the back of the bow directly below the sinew. This meant that the final composition of heartwood/sapwood would end up being around a 70/30 ratio. Perfect!

So after roughing out the face profile and reducing the belly to facilitate better drying, I set about the arduous process of applying 3.5 oz of wild red deer leg sinew, applied to the back of the stave with my own home made sinew glue cooked up from a bunch of sinew scraps and tendon sheathing material. After applying all the sinew and given the glue plenty of time to set up, I wrapped her in gauze and left her to dry and cure out completely for 6 months. And what a long wait that was!!

The sinew backing came out great, so after what felt like an eternity, I fitted a pair of stag horn tip overlays and got a long string on her for a few short pulls. All looked good and after a bit of tweaking here and there, she was soon at brace and being pulled to 26″

As usual, I like to spend a fair bit of time shooting in a bow before attempting to get the last couple of inches of tiller finalised. So I spent a week putting her through her paces so that she could settle in and reveal any tiller correction that might be necessary before calling the job done. For once this bow didn’t budge off tiller, and had settled in to a nice 1/4″ positive tiller, which felt very well ballanced at full draw.

Final touches included a stag horn inlay for an arrow pass, and a gorgeous piece of my home produced bark tanned red deer leather as a handle cover, all sewn up with lace cut from some flank leather from the same hide. To seal her up I saturated the gorgeous grain of the wood with several applications of raw tung oil, caped off with half a dozen coats of Danish oil to fully protect her from dirt and moisture. Last but not least, the glossy Danish oil finish was sanded smooth and polished with fine pumice powder to leave her with a beautiful satin finish which sheds water and really shows off the grain.

I really enjoyed building this bow and will definitely build another “Holmegaard” like this one just as soon as I get my hands on another suitable stave. She’s a little on the heavy side for me personally, but I did enjoy the speed and power that was greater than what I’m used to. The loud whack she delivered when sending my stumping arrows on their way never got boring! She turned out to be quite nippy across the chrono too by consistently sending 550 grain arrows over the sensors at between165-175Fps, which, I’m sure you’ll agree, isn’t too shabby for a simple English yew branch stave!
