Yeah, well I couldn't pass up one of these minisonics to try at a ridiculous price...
I read the instructions, tried adjusting the amounts of rock, water, size of rocks. added a spacer to make sure the rubber latch was holding it down tight... even played with the spring tension adjusting screws and I just never could get much action out of it. Let it run for a few days, but the 220 grit looked barely touched, not much mud.
Well I finally cut a sheet of rubber from an old innertube and lay that in the cradle and viola, action like the above, the speed control actually has an effect. It's an older hopper, blue, not quite like the newer black rubbery ones... I guess the hopper was tight down but must have been loose enough to rock in the cradle back and forth. Anyway, just a 2c if someone else runs into an old minisonic with similar issues.
