RE: Who here sinews?
I have reflexed the tips when I first built the bow. It had 1" of string follow. I think I over stressed it then. So I steamed out all of it on the tips.
So, I decided to perfect the tiller on this bow. And ended up with a hinge 10" from the tip. So I turned my 55lb bow into a 40lb bow. So kinda scared to mess with the tips any more.
