Educate me guys
« on: June 03, 2021, 06:08:05 pm »
So I had a question that I was pondering figured I’d share it here. I have a limb of an Osage tree that’s grown curved. when split the inside of this curve becomes the back of the bow essentially making a bow with several inches of reflex. How much of this reflex can I assume the finished bow would maintain? Also what is the stress factor in that? It’s pretty short but I figure I can sinew back it and then make a shorter draw bow.

IMO, more than about 4" of reflex can cause enough strain to eliminate any advantage you may get from the reflex. I usually add 3" to 4" and end up with 1" of reflex or a flat profile.

My experience, won’t pull out as readily as induced reflex, but more temperamental.

I generally find it is just too short for the intended purpose ::)

Biggest issue is that that wood is compression or tension wood and will change its shape as humidity levels change, branch wood is unstable and doesn't keep its profile
