Thanks for your insight guys. I suppose that finding a glue that will "bond" to the dacron is the biggest issue. As for stretch, maybe used, orn out bow strings would be already stretched out. Well, it was just an idea.
I just got some really beautiful, hard, heavy tropical wood of some sort. Brazilian Cherry perhaps. I thought that would be really nice in a laminated bow or in a thin slice as a pretty back, glued on. Well, i made a test slice, bent it and broke it. It is pretty, but oh, so, brittle.
Your combined expertise, experience and opinions make this a great place to learn!!
