Sure thing:

I have since replaced the drum with a 2Gal cooler from Walmart, a lot sturdier than those weight gainer jars.
Running with round stainless steel media, the results are pretty decent:

Here's a video, sorry for sh*t quality:

1. The 120V motor is from a dead heavy-duty copier, about 1rpm. I think you have it solved with a treadmill motor. I find mine running too hot for my liking, so I put it on a timer: 15min on/15min off. I also have a 24V fan cooling the motor off constantly. I run the timer & fan off a 24V transformer. The hook is JB-welded to shaft coupling, drilled and tapped for a retaining screw.

2. A better view of the motor/timer/fan. I didn't mean to over-engineer, I just had parts lying around.The total tumbling time is under 3Hrs.

3. Coupling motor to the drum: my way of giving the rotating drum some slack:

HTH.
I had 4 aluminium ribs riveted inside my original drum, the one made out of a weight gainer jar. The rivets eventually begun to leak... I have no ribs in the current drum & found it makes little difference: the drum rotates at about 60rpm, i.e. fast enough to cause the load tumble onto itself instead of sliding. I'm sure having those ribs helps, I just didn't feel the difference would warrant the extra time to tinker with it.I cheatedand took the easy route and bought an RCBS Sidewinder but congrats on a great looking set up. Well done!! A quick question, did you put anything in the way of ribs on the inside of your drum to promote tumbling of the brass and media? The reason I ask is the interior of the drum on my sidewinder has a flat spot profile for that reason.

Thanks. After 3 tries, even I was able to make it work.Thanks for the info and your experience. Very helpful and I'll pass that on to a buddy who's thinking of building one. Again, your set up looks pretty good. Good job.
Here is what I call mumbler = m+(t)umbler. The only thing I paid for was the motor ($3), all other parts were taken from scrap. It can clean about 100 handgun cases or 40 30-06 cases at a time. Its great advantage is that it makes no noise and can turn several days with no problems. Once I forgot it for a week. With a special box, I use it to dry my cases after ultrasonic cleaning.
