Yew billets belly drop build with sinew backing.

Spent an hour on the stave today and got it worked down some. It’s at basic dimensions of the other for the most part. It has some heat correction that needs attention and prop twist at the tips not not too bad. Took sapwood down to about 1/8” approx. it was quite thick before.

My best yew bow was made from heartwood only billets and sinew backed. Old hippy gave them to me at the 2015 Classic.

Well that sounds promising then! Thanks PD. Let’s see if I don’t screw it up then. It will be interesting to compare the two as far as performance and other shoot ability factors like handshock or final mass as such. I’ll dimension them similar in build dimensions but to get both of them to same weight in draw it may vary somewhat as the yew stave is quite crowned and the heartwood only is very flat. I may try and round it a bit though a bit more. My goal is to get two shootable bows in the end. Not terribly scientific here but should be interesting anyway.

Dave,
Since you're sinewing the stave have you considered flattening the crown to even up stresses in the wood? You may not have enough thickness to do that, though.
Just a thought,
Mark

Mark, yup I did a little decrowning. I didn’t want to go right flat as to compromise the sapwood too much as this would negate the point of the comparison of the two builds. It still has some crown but I did remove some so hoping it will work alright. Right along the top peak of the crown the sapwood will be slightly thinner then on the rest of the bow. The other alternative I’m considering is to hollow out a little the belly to compensate for this crown. We shall see how things progress with each. Today I’m working on the flipped tips on the billet bow. I also glued on a flat piece on the handle of the stave bow to better match the billet bow. I’ll post some pics of my progress tomorrow. Thanks
