It’s easy to look at all the finished work out there and forget that not all pieces make it. Here’s my latest “failure,” it was a 10” wide by 6.5” tall hollow form until a nasty catch saw to the end of that. I only had a little over an inch to hollow, and had the walls down to about 1/8”. I had a lot of hours into the piece, but hat’s just how it goes sometimes! ETA: note, the second photo is after I trimmed up the edge after the catch. The original opening was about 3/4” diameter, so when the tool caught it blew out the top.
