I have 2 rough-running, four-point, orbital, oscillating buffers that need to run smooth again.

These are heavy duty, 2-handled, 2 Amp, 3240 rpm, four-point, orbital, oscillators that were converted to professional massagers. Both of them now run really rough and I can't keep buying new ones nor can I afford to ship them back to the company for refurbishing. I assume they only need lubrication, but I can't figure out how to open them up nor does there appear to be any one around here who repairs power tools. (Rock and a hard place, eh?) Can anyone help? I have a photo, although those two black knobs do not exist on my units.

Rough? Metal-scraping against metal rough, or not very-smooth motion rough?
You might be right, or there may be some flexible bushing in there that needs replacing.
I see pop-rivets on that, pop-rivets can be drilled-out and replaced (e.g. with more pop-rivets).
If you can't use 'em - take one apart and see what you find.

 No metal scraping, but loud and very rough motion.
I'm thinking there's some rubber (natural or synthetic) that used to damp out the roughness, and it's worn / cracked. I saw this on an orbital shaker once.
Get it in bits, it could be an easy fix.
