Re: Question about Unicolor Uni Roller 352 Motor Base
I tried one for polishing rifle brass with corn cobs. While it work fairly well I really believe I would wear out the motor and bearings by the continuous use
so I stopped using it for that purpose. A barrel of rocks is even heavier.
The reversing of the Uniroller will not help at all in rock polishing. Actually, will slow down the process.
Re: Question about Unicolor Uni Roller 352 Motor Base
Could a viberatory tumbler do what you want? All the ones I've seen are from the PRC and low cost.

Thank you. I have decided against purchasing the Uniroller for this purpose. I also notice that is price at auction has jumped to $55! Unirollers are popular here in Japan.

Wow, that would be great since I hear that the vibrating type are faster. Is it on aliexpress? I had a look for a rotary tumbler, but could not find one. I purchase a lot of stuff from the people's republic. I would be grateful of a link. Is it okay to post links to vendors here? If not please be so kind as contact me via the email link on my homepage at http://nihonbunka.com

There are vibratory tumblers from China, but the cheapest I can find is more than 200USD.

Re: Question about Unicolor Uni Roller 352 Motor Base
Just some FYIs-
The Uniroller 352 change in direction is controlled by the size of the capacitor. Swap out with a larger one and the length of time between changing directions is longer.

Also, the lubrication may seize up on an older unit that has been in storage. I bought a 'dead' one off eBay, by moving the large wheels by hand, it freed up and now works fine when powered.
*
When opening up the base, unscrew the center screw last. There is a large plastic washer that may become loose or lost.

I have successfully used a foam roller (from Amazon) as a holder for my stainless steel tank. There is an 8" foam roller that would need some counter weight to work correctly.

I normally use an older JOBO tank with the 352, I did this as a proof of concept.
10 60d nails (6" long) would provide enough counter weight.
The setup pictured was actually used to process the color picture.
The foam is a great insulator to keep the chemistry up at temperature.
