Thread: case tumbler

I've been in the middle of making a tumbler as well.
Gone real simple though. Using a 12V wiper motor and a 10L paint bucket spinning on skateboard wheels. Still got a little to go before it's fully operational, but I have given it a test run to test my ideas and it works fine.
Stainless pins are going to be the most expensive part. Everything else has been free so far.
This tumbler will be great for doing the tons of brass for the AR's.
Test run was using a 7ah spotlight battery. I have now wired in a laptop DC power supply to power the wiper motor. A 3 way switch means I can change direction to wind the bucket on/off. I've also slowed teh speed down a bit. Didn't realise I had it in 2nd gear for test lol.
I like the idea of using some conduit for agitators. Might have to steal that idea

Here's the test run vid I made.


I've also been making a smaller version using a battery drill motor and old coffee tin to do smaller batches of brass.
Only thing left to do is attach grip tape to the drive rods. Test run with tin full of water worked OK. I have since closed the gap between the ends so the rods don't bend too much.
