I thought this was an great idea. I had a bunch of coral left overs that I didn't think were interesting enough to waste the grit to tumble them, but figured I'd give them a week or 2 of free churning to see if they might turn into something worthwhile. I filled my 12 pound barrel right after reading your post and I'm real interested to see what happens by next Tuesday. Most of my pieces are egg size or bigger. I don't know if that will help or hurt.

When I run quartz with coral I wet grind for a week but then add 80 only if I need to.  Mostly I just go to 220 after the first two weeks.  It's a great set up for the 600grit.
