Eric, Thanks for your insight, I have had good luck with bamboo and hickory as a backing. I never thought of using heat tempering on a nonworking backed bow before I start tillering. Will try that.
Pat I will try working midlimbs first, I became interested in trad bows just before Christmas. As a Kid I made chokecherry bows for gopher hunting. The gopher tail bounty back then was two cents a tail, Ten gophers was a pocket full of candy.
Tillering the bow limbs is pure magic, love the challenge. Thanks
Joe
