Hello, slightly older than me younger brother! :D
1) Selfbows can be had in your draw length. Overdrawing a selfbow made for a shorter draw can break it.
2)Once you can shoot your selfbow well, and know what kind of arrows it likes, you can haft "boughten" stone points to matching shafts.
3) Contact Ted Fry (Raptor Archery) about your dream...he can help.
4) It is not a sin to use stone points with a laminated bow. Either that, or I am going to Hell and not waiting for a handbasket.
