Thanks for the wood plug idea Bowdoc.
Man, I'm getting kind of excited that I might be able to use this bow. My brother got it in some kind of hornswaggle trade in a gunshop in Livermore, CA when we were still young men. Then I traded him something for it. It seems that crack was always there. But I'm not sure now.
At lunchtime I'm going to go out and buy a propane torch and give it try in a day or two. I'll report back with before and after pics.
Thanks,
Steve
