[QUOTE="oldbullhubbard, post: 577721, member: 8944"] Hi. The instruction book that came with my new Lortone tumbler recommends 7 days use of aluminium oxide after 220 grit and then a final 7 day polish using aluminium oxide. I have used 600 grit for years before polishing. What do people think? Your advice is appreciated. Regards, Old Bull Hubbard. [/QUOTE]
