Cottonwood tends to fuzz and takes some careful attention to clean up. Yes you can sand it to get rid of fuzzed grain, but I don’t like sanding. I have been able to use a round-nose scraper in shear position to leave a good surface. So I thought about trying a cabinet scraper with a rounded end.
With the lathe running at a moderate speed, I hand-held the scraper in shearing position against the interior of the bowl. (The left hand provides the fulcrum while the right hand holds onto the back-end of the scraper.) When the scraper started vibrating, I knew what I would see when I shut down. So I went over the area a couple of times to deepen the pattern. When I shut off the lathe, I had some nice spirals, which I burned with a pyrography tool to highlight. I like the results.
