fishfinder, your comment made me laugh out loud.
ionicmuffin, I wouldn't dare shoot an arrow from it since I'm not exactly sure where it would go! But imagine I cut it in half and added a realistic handle. The bow would be less stressed and shootable. It would just change weather patterns when shot.
Scott D, I literally went out and got the piece right after dinner. I believe in the design principles I speak of. No frets at all. It's completely flat on the belly as I tillered it with my belt sander. Also I trapped in towards the belly to take some strain off the back. Even so it's only taken an inch of set.
Dictionary, you should definitely make an osage bow. It's great wood.
