Phi for All 5872 Posted September 16, 2012 If you can borrow a variable speed hand drill from a gullible relative, I'd drill a hole in that empty can, run a machine bolt through the hole using rubber washers and a matching nut on the bottom of the can. Put the end of the bolt into the drill's chuck, tighten and now you don't have to stand there rotating it by hand. 0 Share this post Link to post Share on other sites
InigoMontoya 82 Posted September 16, 2012 Rock tumblers are pretty cheap. Buy one on ebay or craigslist or similar. Done. 0 Share this post Link to post Share on other sites
