As I turn my blanks, when the final profile is achieved, I remove the turned blanks from the lathe, and do all sanding by hand, longitudinally, with the grain, As stated in other recent threads I typically go 320 grit, 400, 600, 800, then switch to MM, 2400 thru 12000. All done by hand, with the grain. When I finish, there are ABSOLUTELY no RADIAL marks on the blank as seen with the naked eye and with a 20x loupe.
Then comes the finishing. Opting to use friction finishes, it is back to the lathe. RPMs? I have tried low, ~700, and I've tried high, ~4000. No matter what speed, nor how I apply the finish - clean cotton, clean blue shop towel - I get radial ridges, almost like sanding marks. HELP! Please!
Any and all suggestion are appreciated.
