I'm building a dry tumbler for my brass. Wondering what the speed range (RPMs) is of commercial tumblers and their diameters so I can convert that info for the 14" diameter steel drum I'm using.
I looked at commercial tumblers and for their tiny size, they sure are expensive. I have a couple small steel drums with gasketed, clamping lids, some non swiveling casters for it to ride on. I plan on coating the inside of the drum with construction adhesive or similar to reduce noise and give some grab. I may even give it grooves with a notched trowel or glue cross bars on the inside.
I plan on using an AC gear motor, pulley and V belt from McMaster Carr which will cost less than half of the commercial tumbler I was looking at and about 20% the price of the RCBS unit.
I need to choose the speed of the gear motor and size of the pulley so I can approximate the speed of commercial units.
