Chip,
3/4" for your spark gap does seem a bit wide. You must have a good capacitor
to hold up with a gap that wide. I think my safety gaps are set at about
1/2". The widest gap I ever used with the neons was about .150" - using a
cylindrical gap with each individual gap at about .030". Now with the pole
pig I am using a rotary gap in series with the static gap. The safety gap
only fires when I get a strike down into the primary.
