I'm looking at this old tumbler a bit more closely. I called RCBS asking for a replacement motor and they said no dice - I guess it's old enough that they no longer use that motor?My shaker crapped out this past winter. I purchased both a new shaker and ultrasonic cleaner. Luckily, I have a slop sink in my basement mechanical room. I also bought a cheap toaster over works great for drying cases.
In any case, I'm hunting online for a matching motor, and while I can't find that specific model number, I think it's a pretty basic motor. I just have to make sure to find one that has holes in the same places the mounting studs are located on the original - I can move the mounting studs from this motor to the new one.
If I can get the old one rolling again, that would be great to have on hand - possibly for use with a different media, or just to use in tandem with the new one to process more brass at once.
