I got a chunk of osage I cut last year. It's cured. I wanted to make a bow from it, but it had too much of a twist in it for a single stave. Might work for a take-down. It's about 5" in diameter and 84" long. Twists about 90* down the full length.
I'm always looking for staves...any kind. Also like anything leather, ready to go strings, knives, whatever. The osage isn't worth much to me so I wouldn't be looking for much in return.
