Re: Strong Rotor Material???

Original poster: "S&JY" <youngsters@xxxxxxxxxxxxxxx>

Gary, McMaster Carr sells GP03 electrical grade fiberglass that works great for rotors. www.mcmaster.com. Recommend 3/8 inch thickness. A 12 x 12 piece of this only costs about $13. Part # is 8549K47. Be sure to have enough space between hub and your electrodes so there is no way sparks can jump between them. I would say you need at least a 5 inch diameter rotor. --Steve Y.
