I made it myself, it's slightly off balance but the vibrations aren't unbearable.
1800 rpm, 120bps, used a standard AC motor and had the universities machinist mill flats in the rotor about 3/32" deep at 90 degrees. Works like a charm.

Yeah, spark gaps can be tricky, though I only have anecdotal knowlege of them from teh reading I have done over the years about tesla coils and how they can arc back all teh way to the power station, the most famous instance being tesla himself melting down a generator at the power plant in colorado. :) FUNKY stuff!! someday I'll build a tesla coil! I've wanted to build a singing tesla coil for a LONG time now.
He actually blew the dynamo at the power station there. It would be pretty hard to kick-back any kind of voltages back to the power station on our modern distribution system...
My setup uses a pair of air-cored choke tubes that should provide a reasonable amount of resistance to kick-back.
I considered powering it off of the UPS I bought for my PC. OR getting a power inverter and some solar-powered home batteries for total isolation, but that's a bit extreme.
