I've been getting caught up on brass cleaning and late last night my Midway Tumbler up and died after a year of faithful service. Being the fixit guy that I am I opened it up to see if I could spot the problem. One of the wires had broken at the connector. I have a bunch of similar connectors so I took it apart and fed more of the power cord into the base, attached a new female connector tested it and reassembled. Originally they didn't have much wire slack in the base so the vibration worked it's wonders on the weakest link and finally broke one of the wires. You'll want to watch the polarity as it affects which direction the fan pulls air over the motor. Pretty simple device actually, a motor with fan and a weight on the fan which throws it out of balance to creat the vibration. All in all only took me about 20 minutes to fix and saved a lot of hassle.

I read your Midway tumbler post. Midway had a recall on thier tumblers several years ago. I believe the motors were burning up. The reverse polarity, and fan pull, could have been the problem. I thought you might like to know this fact.

I had much the same thing happen to me with Lymans big tumbler. Called em' up (No way to open motor cabinet), asked em' whats up with it. They said its non serviceable and to send it in with 80 bucks and they would fix and return.
Out came the dremel, cut the connecting points on the plastic air vents on bottom, found the loose wire, repaired and back in service in about ten minutes. (found out later that replacement motors are less than $20. locally, not from Lyman). Non-serviceable indeed!
