Chicago Pneumatic Dual Drum Rotary Rock Tumbler from TNM

Still running and live how it works. Live it.

I Love it! for beginners or novice this is awesome!I'm buying another

This is NOT beginner friendly and not well built. Within the first day running, the motor on mine overheated and seized up. I was able to track the problem down to the fact that the place where the belt attaches to the motor does not have a good space to seat the belt. It was rough and too narrow, causing the belt to catch and stick, putting strain on the motor. I had to repair the thing before I could use it, widening the gap and sanding it smooth so the belt doesn't catch. This thing says it's got 3 pound per barrel capacity and I've only run it with 1.5 per barrel and the motor still doesn't like the weight. The motor simply isn't strong enough to tumble that much weight. The motor gets so hot I've been leaving the top housing cover off and running a small fan directly on it to help cool it. I've oiled everything that can be oiled to help make it run smoother and it's still a huge problem. While the metal housing makes it a bit sturdier, its design makes the motor compartment smaller and more difficult to work on, change belts, etc.

Broke a few belts but I've seemed to have that all figured out (tension wise). Would definitely buy another one

Easy to use. Straight out of the box tumbling all my rocks! 😊

So far all is working well and I have 2 running of these running at the same time and there is the noise of water and the rocks turning it is relaxing not too loud. I purchased this one at about $30 dollars more than my first one I bought. If I wouldn't have already liked the brand I wouldn't have purchased it at that same price. But I will get alot of use out of it. They are continuously running and no issues at all.

Does a good job of polishing.

Ours only worked for 2 months. Then stopped turning (just makes a whine noise). Seller won’t help with warranty issues and the extended warranty company says they won’t help because it should be handled by the manufacturer’s warranty. Huge waste of money, don’t buy.
