The Lortone Model 33B rock tumbler features twin barrels running at the same time on a single stretch version frame assembly. It has molded rubber barrels with screw down leak proof barrel closures. Rubber barrels run much quieter and with less slippage than cheap plastic barrels. The barrel interiors measure approximately 4" diameter x 4" deep. Great for polishing rocks with a radically different hardness. Run softer rocks in one barrel and harder rocks in the other. This prevents the harder rocks from destroying the softer material. Each barrel holds up to 2 pounds of rough rock when properly filled with the barrel 2/3 to 3/4 full. Illustrated instructions included. Tumbler grit not included.
