I built three of these for 15 balls with the harbor freight buffer. The two newest buffers burned out in less than two minutes. Seems the platten was too big. From my experience the better way to go is with the buffer on top of the balls. Cheaper, and you can use the buffer for other things.
Yours is a nice rig and should last a long time as the platten is not too big.
The other idea I have seen and now think is worthwhile is to have dividers to seperate the balls. Seems I have to clean, let sit until there is a haze on the balls and then polish. Because my buffer (on the only good one) is on the bottom I can hold a towel on top to get a shine. But this could be easily done with a change of bonnets on an above the balls cleaner / polisher.
