Barrel size determines how much rock you can tumble per run, from one-quart hobby barrels to gallon barrels and production machines. Multi-barrel models let you run separate grit stages at once. Rotary tumblers run continuously for days, so consider noise and where you will place the machine.
Remember that grit, polish and media are needed as well as the tumbler itself.
