Good vid! I have felt the need to build a selfbow and kill a deer with it for a long time. I guess I haven't done it yet is because I am challenged pretty hard just to get good at shoot a laminated recurve or longbow and get deer killed with those. But I have had some sucess over the years.
I am thinking maybe a Hickory is the best to learn on, since I don't think any special backings are required.
Anyway, good vid, and I found the nock ends of that bow, interesting, as no cuts are made.
