BTW, this is the first bow that I have ever done. I am in the process of making one for myself. This one is a simple oak with walnut backing, and the riser is alternating oak and walnut layers. I thought it came out pretty good for my first.
Also, when I went home to OK for Thanksgiving, I cut a nice 6" boise de arc / osage log. It is on my garage floor just waiting for me to dive into it. Its got some nice wide rings and a little built in deflex. After I finish this bow I'm making, I think I'll see if I can turn an osage log into a bow.
