try to make the rotory electrodes at least 1" long from the disc to the end
of the electrode, I
have found that anything much shorter has a tendency to arc to the disc by
about 1/2" before the
electrode at 14KV. ( maybe my timing was off a bit , way too early, but
spark length was really
good at that setting)
