I arrived at a novel electrode geometry for mine. 5 rotating electrodes
and (4) fixed electrodes such that each of the 5 rotary ones come into
proximity TWICE per fixed electrode posts. Thus doubling the commutation
rate without increasing complexity of high-velocity parts. I also used
compression-type tubing clamps on the rotary electrodes. This allows for
full use of the tungsten and ease of adjustment. The clamps grip the
tungsten post radially to insure tightness. Haven't had one loosen in 6+
years. BTW, the gap uses a 3600-rpm salient-pole (modified) induction
motor. Been working incredibly well.
