Yeah, you'll have to chase a ring or smoke meat with it I'm sure. Was you just trying to get the muscle looking lumps and bumps off or were you wanting a dead flat back? I suppose if you wanted a flat back, you could try de-crowning it, but would have to follow every contour of the back just like chasing a ring. If you make bows from staves, I'm fairly certain you won't find a stave with a flawlessly smooth back. All will have bumps, ridges, dips, and doo dahs. That's just part of the beauty to me. Every stave is different.
