Now we are back to "I love to chase a ring". Some of the Osage and others I have worked, the bark and sap wood came off pretty easy. On others it was like chipping away at a cement slab. The bark and sap wood broke off in chunks. I will say that those tended to be really good bows in most cases, so a price well worth paying. Still, once you are down to the hard wood, and you have exposed the tiniest part of the ring your after right at the edge of the stave...Running the draw knife is almost an unconscious thing from that point on. Zen and the Art of Ring Chasing.
