Does it fit in every bearing size?
I don’t think so.
What?
How about a little clarification…
I’ve got an electronic jewelry cleaner that I sometimes use to clean bearings. It’s basically a dish that I fill with denatured alcohol and it sits on a vibrating platform.
alright, clarification. the one I saw cleans bearings the size of the one in the DM2, It won’t do smaller ones. I usually clean them by hand.
Wow 3|3ctric bearing cleaner!!
