A friend of mine in VA cut some Osage a few years ago but had not been able to make the time to make a bow out of some of it. He had started on one, roughed out, and that was about it so he asked me if I would tiller the bow out for him, I said sure. He sent me bow, it was a nice piece of wood. Decent rings, not too thick, not too thin. I started out by removing the sapwood that was left on the back and then started tillering it. I didn't realize how good the wood was until I had the bow most tillered out. I didn't measure the reflex, it had a bit, before I started but if it lost any of it then it wasn't much. The bow is 65" N to N with 1 3/8" wide, shallow D section limbs. I tillered it out to just under 60# @ 26". I haven't shot it yet but it has very good string tension. Here's some pictures
The string is made of some Linen I picked up on a popular auction site. The linen came as thread, 35/3, that I plied up. It's just under 1/8" thick and has a break strength of just under 300#
