It's a board that I got from a hardwood place nearby. I've made several longbows from it, and most have been great. It was the nicest, straightest grained board I've ever seen. I'm sad because this is the last piece. But - I have a bunch of branches cut from the ashes in my front yard, (one of which is large enough to make one bow for sure) that have been drying since last summer. They should be just about right now.
I was thinking of backing it to prevent an accidental blow-out. I have a long piece of of hickory (board, from the same place, almost my last piece) that I was considering. I've had success with hickory backed lightweight longbows. Is it necessary if the back is fairly even but has a few grain violations?
I am working it to a rounded rectangular cross section. When I tried to make one in a pure d-bow shape, it shattered. That also could have been due to not being careful and patient as well. I am definitely going to keep it long - right now it's 76 inches and I'm going to try to leave it there, then put tips on the ends. I don't have horn, but I have some antler that should do nicely. Stuff is hard as bone, though.
Weight-wise I'm aiming for 80 to 100 pounds. I'll aim high, then work it down as I tiller. Right now, It's probably 150 lbs or so just to brace the bow. I'm certain it would break long before it reached draw, and there's no way I could even apply that much force, I'm sure! But it's great because the profile is looking good, and I know that I have a lot of wiggle room to keep it even while I work it down. Slow and steady and all that.
Thanks for the advice - I'll definitely heed it!
