I'm going to try the pressure washer I think. Was peeling the bark with my draw knife and cut through one of the ridges on the back right off the bat. It was at the end and it's a 7' piece so no worries, but it sure put me in low gear. I knocked the bark down to near the cambium with my draw knife and then flaked the stringy cambium amd what was left of that brittle sponge like bark with my pocket knife. Real slow, but I got good backs.
Yes, there is a black walnut. Split weird, might be the only stave out of that log. I'll try for another but don't know. The sapwood is real wet and soft and wanted to come off with the bark, so I put that on hold also. I'd like to try to make a bow from it though.
