You sure that thing isn't a centrifuge?

Put a rheostat on it to reduce it to around 100rpm or less. The goal is to <span style="font-weight: bold">tumble</span>...without beating up the brass.

If I'm not mistaken, the Thumler's Tumbler is only 30rpm. Your spinning the crap out of yours!

Unless that motor is built for less volts(that is what a rheostat does is to "cut" the volts)you will end up killing the motor.
IF this tumbler is belt driven you will have to play with changing the pulley ratio.

Re: brass tumbling

Hadn't thought about that, LG.

As it's already driving it at high RPMs, I doubt the motor would sustain low input if it's directly driven.

Good call!

Re: brass tumbling

thanx for the input im driving it with a belt so i will work on reducing it down I thought that was the case when i saw that the media was chipping the bucket thanx again

Re: brass tumbling

Put the larger pully on the bucket side. You'll need a new belt too.

The MOTOR is what he was talking about, not the actual tumbler.
