Single 15-Lb Barrel Rotary Rock Tumbler (Thumler Model B)
This is the Big Guy! One 15-pound capacity barrel with drive motor. Very heavy duty steel drum with replaceable rubber liner--gasketed end closure is secured with wing nuts. For the tumbler operator who desires a heavy-duty high-volume rotary tumbler.
A Great Idea: Consider combining this big rock tumbler with the Model B Conversion Kit--this kit instantly turns your single 15-Lb barrel tumbler into a pair of 3-Lb barrels with the same machine! Savy rock tumbler operators will use the 3-Lb system to save money on powders while they test various rocks to see if they polish well--then, when they find some really good rock, they switch to the 15-Lb barrel for high volume production.
