Snooping around. I just found this on the Seatle Woodturners website, June 2026 newsletter. See on page 5 some helpful hints. By the way, they have a very large club and a wonderful website, I think designed and managed by Joe Cornell.
We don't have a coloring lathe, but a cool addition. Someone wanna engineer and make 1 for the fair? Looks fairly simple.
