Chip,
Poor ballasting will do it, probably a low vaporizing
temperature metal for the gap would also cause it.
When I was doing ballasting experiments with a resistive ballast
connected to my pig's primary and the pig's secondary connected to my
cap and rotary gap only; I could "power" arc completely around my
rotary gap. The gap became VERY quite, just gentle hissing. As soon
as I introduced some inductance into my pig's primary circuit, the gap
started quenching in a very short distance.
