I was turning a waterfall bowl in Australian Burl and one the back side I had some tool scratches on one extra long wing. I was concerned I would break it if tried while lathe turning. So setup piece in lathe then sharpened the scraper to razor sharp. I then turned the headstock plywood back and forth by hand taking beautiful small shavings off until wing was clean up better than if I’d turned it. The plywood was attached to a faceplate.
