Homemade Ball Polisher, Drill Powered

[Mick]

Here's a drill powered polisher I came up with that works pretty good. I think it cost about $20, most of that was to buy fidget spinners for bearings, and ready rod for shafts. The rest was scrap I had laying around. Feel free to steal/modify the design.

Now this is a great idea. Keeps the cost way down as there is no motor and seems fairly simple to build. This should be mass produced.
