Hi Bart,
I have 8 flying electrodes on my disc. Each of these flying
electrodes is a 3/8" x 1.5" long solid tungsten rod. Of course
since my rotary gap is an ARSG, I can easily vary the speed
and break rate. I had been running the GM in the 300 to 350
bps range but I was probably running closer to 400 bps
during the last firing (I set the speed control variac to 85
on the dial instead of the typical 75). Doubling the number
of flying electrodes and actually installing them is a bit more
than I would want to try to tackle, so I'll just keep the power/
break rates down to more sane levels in the future ;^)
