DIY Rock Tumbler and Polisher
Description
Just a quick DIY rock tumbler. Parts include: * Motor mounting bracket * Coupler for attaching tumbler shaft to motor D-shaft * Support bracket for powered shaft * Brackets for attaching the boards perpendicular Parts you will need: * Boards to build the actual thing * A hole saw or some other way to drill the holes in the boards * A motor. I used a 12V 100RPM High-Torque DC Motor. I used this one: https://www.ebay.com/itm/183846644222 * A power supply for the motor. I used this one: https://www.ebay.com/itm/264310583780?var=563897081879 * 1" PVC pipe for the 2 shafts * Rubber bands to make the shafts grippy. You could also use a rubber sleeve/hose of some kind or some shrink wrap tubing for this. * Some 1/4" bolts and nuts for mounting the motor mount * A M3x10 machine screw to lock the motor coupler to the shaft
