Box Fan Dual Drive Rock Tumbler

Box Fan Dual Drive Rock Tumbler

Used 8mm aluminum rods, 608 bearings, box fan motor, M3 screws, 5/16 nut and bolt, a 6" x 1/8" O-ring, and a random o-ring I found in the garage (I think it's an oil filter o-ring) to make this tumbler. Was able to drive an 8" barrel made from a PVC pipe without putting a sleeve on the aluminum rods.
