The Model B rock tumbler is a large capacity tumbler that is great for a person who wants to
tumble a lot of rough. If you have the luxury of collecting your own rough then this tumbler
might be perfect for you. It has a 15-pound capacity barrel that when loaded 2/3 full
will process about 10 pounds of rock quietly.
The barrel is constructed of a metal frame with a quarter inch thick rubber insert that will
tumble the rock with minimal noise. While most Thumler's Tumblers have a plastic lid held in
place by a retainer ring the Model B lid is a metal plate that fits over a thick rubber gasket.
The lid is tightened down by six washers and wingnuts. The rubber gasket creates a
watertight seal between the rubber insert and metal lid. The rubber seal also covers the inside
of the lid to make the tumbler operate quietly. Comes with a factory Warranty
This is the low speed Model B that is powered by a quality motor with overload protection that spins at 1550rpm. The metal base and barrel have been
finished with a powder coat paint job that will resist rusting for a long time. This is a very
high quality machine.
