Sometimes you just need a little... more; more capacity to tumble more rocks. There's not a universally accepted definition of what a large-capacity rock tumbler is, but we think of them as anything that will let you tumbler more than 6lbs of rock at a time.
We have some great machines from Covington, Thumler, and Lortone. They're all built in the USA and have a complete selection spare parts available so you can keep them running for a lifetime of service.
