Buffing Machine Guide
For a buffing machine, you'll want at least a 1/2 HP motor that spins at 3450 or 3600 RPM. One with an extended shaft is best, so you have lots of clearance to buff your parts.
If you'll be doing lots of buffing, opt for a 3/4 HP motor. Also, a 2 speed (typically 1800/3600 RPM) machine offers more versatility and is a great option.
Personally, this is the machine I use (Baldor motor, will last a lifetime) http://cjn.mx/baldor

The pads I sell can be used on a machine with a 1/2", 5/8", or 3/4" shaft.
If you have an existing machine but need the big washers that hold the pad on, here's what I would recommend
If you need the spacers to cinch down the pad https://amzn.to/2LkDalL

To use the pads on a drill https://amzn.to/2HI3lR3
Lastly, whenever you're doing any sort of grinding or sanding you'll want to use eye and respiratory protection. Trust me, you do not want to be breathing in metal particles!
The absolute best product for protecting yourself is this https://amzn.to/2zPKoaN
Alternatively, this is also a great respirator to pair up with safety glasses https://amzn.to/2LnhHap
Use these filters with the previously mentioned respirators https://amzn.to/2MTfJC1
If you're doing lots of buffing, I'd recommend getting some sort of ventilation like this exhaust fan that I use https://amzn.to/2P9GoKx
