Years ago a friend gave me 3 osage staves that should have been in the burn pile. These three staves had about every malady a bow stave should have, knots, pins, twists, checks, bends...well you get the picture. That winter I put my mind and the knowledge I'd learned from other wood bow builders to work and by spring I had 5 shooters. Not pretty, not symmetrical, not straight but all worthy shooters. I learned more about osage and wood bow building from those 3 staves and few months than from any other bow building experience I can think of.
Staves like this can really teach you a bunch if you allow it to. Looking forward to your progress and success.
