Daryl,
This archery post is very interesting to me. I and a friend down the block have just started making some selfbows. I have only completed one,(too busy with double guns), but he has made several. Mine is made of Hickory but he has used Elm,Oak, Hickory, and Osage Orange. We have also been playing around with some Black Locust. Only time will tell which of these woods are best and hold up over the long haul.
I have so many questions to ask you about this, I am going to wait while I organise my thoughts, then I'll P.M. you with a few of them. I know you are a busy guy and I don't want to tie up too much of your time, but you are the only guy I know of who understands this stuff! Many more questions than answers right now. Thanks for posting this. Bob
