Bernie, after building wood bows for as long as I have I have gotten used to these sorts of things. I get bummed at first but soon get over it and move on to the next. If you let it get to you it gets too frustrating and can kill the passion.
I purposely picked another difficult stave for this project like I did for the TG bow trade last winter. It helps me learn more about the wood, the process and myself. I knew going in that there might be a 50/50 chance of success so then the /50 happens I try to move on. I will do what I can(after the New Year) to make this bow work. I have gotten some good advise from a few folks in the know, like Art Butner and others, so I'm probably at the 50/50 place once again with this one. I truely hope it works out but if not, I have learned from the experience so it is not a failure and never will be.
