You will be reincarnated with a 10 ton capacity tumbler Chuck.I wonder what size tumblers they use in China.My Garden center clients buy 50 pound bags of tumble polished jaspers and agates for less that $100.They are not real flashy and i am guessing they were creek rock and they just ran 220 600 polish. Tumbled glass too. Mean looking tumbler for sure.

Don't forget about the cost of grit to feed it...

Egad! Imagine the overall effort involved in running one of these things, from sourcing to marketing.

I forgot to mention the ebay seller has two of these listed that are almost identical so he had a total of 16 of the huge barrels rolling at a time. I could not even guess how much time would be involved in weekly clean outs and there's no way you could sort each barrel to see whats ready for the next stage. I know when we have all of our tumblers going quality control suffers compared to when we concentrate on a few 3 pound batches.

I find tumbling to be a lot of work.I have learned to pregrind and then tumble.Or chip glassy materials like clearish agates.Tough materials like cherts are a lot of work prepping for tumbler and i waste more than half due to fractures.Of course slabs are great to tumble.I find myself picking thru after a week ot two in the 60/90 stage throwing out junk and rebreaking stuff that is fractured on the fracture lines.Especially recracking on the fractures and putting it back in early in the coarse grind op. I can not imagine keeping those Ebay tumblers going.Tumbling is expensive,grit + electricity.I pretty much pick thru step 1 and collect rocks ready for step 2,leaving the rest to keep tumbling.It's been months since replacing the step 1 load 100 percent.The smaller stuff grinds faster,as does stuff rounded by nature.Sounds like you guys sort too.
