This is for anyone having problems with their RCBS tumbler motors. I was having problems with mine and came to find out that the motors in cheap fans and humidifiers are very similar. First just tried to replace motor but that didn't work. Wasnt enough power in the motor. When I took my old motor out I found the housing for the fan shaft was broke. Took it apart and replaced it with the housing from the fan I scraped. Works like a charm now. I have 3-4 of those motors and although they are all a bit different they all seem to be same shape, size, and mount the same. Here's a pic of the motors and housing. Not sure if Lyman and others have the same motor but it wouldn't hurt to check.
