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
