I use a UV-18 Industrial tumbler for everything past the initial grind. For that, I use a rotary with (2) 12 pound drums. I get outstanding results on "most" materials. I've been trying to polish scrap glass, the kind you'd find in an old dump & had satisfactory results, but not perfect. Also I've been trying to polish cubes of obsidian. The smaller pieces (<1/2") turn out perfect. The larger ones I've tried lately, (about 1" cubes) have a slight bit of spalling on the edges. So this is why I say most results are outstanding. I'm still learning how to get perfect results on some materials. Jaspers, agates & most stones in the hardness range of 7 turn out amazingly well. Some people get discouraged with vibratory tumblers. It takes time & some experimentation but I think they're a very useful tool. There's not a lot of "how to" information on them that I've been able to find. If you want to get rid of it, I'll give you $150 for it!!!

I am about 3 or 4 days away from the first batch.I have have two tumblers a Chicago and Lortone.Both effective but slow and very old .I have a rebuilt lot-o-tumbler I made it a double barrel by welding two old together. The UV-18 seems very fast.I started the first batch with agates three or four different kinds now we wait.................................
