So I put a bunch of stuff in the vibratory tumbler to see what results I might obtain giving it a several hour run. I grabbed a couple of handfuls of loose hardware from my bin and tossed them in the bowl:
About 20 seconds after turning the machine on, the parts are already being covered over by the undulating media:
I let it run on "medium" speed for about 3 hours.....
..... and here is a selection of the rusty and dirtiest pieces. A bit dusty from the clay cat litter, but otherwise really clean!
A quick wipe down with a cloth of some of the parts. Frozen and seized bolt and washer on the right now turns like new.
This old hose clamp of covered in rust and wouldn't turn at all. Garbage right? Wrong!
I really want to see what an overnight run will do, but I think these results are conclusive. My $20 used parts Amazing Tumbling Machine is a success!
