I have an osage stave that I turned into a bow. I steamed the stave three times. One limb stands relatively straight, the other has 1-1/2 inches of set. Tried dry heat also. Every time I "fixed" it, it held for a few days then went right back. the stave was cut 15 years ago, quarter split, debarked and sealed on the back and ends. It just wasn't meant to be with that stave. By the way it shoots like a dream. My niece is gonna love it.
