Ingenious idea there Jim! I would be a bit concerned at to the maxium
voltage you gap can handle though. As I remeber the old variable
capacitors they worn't built for high voltage, so keep an idea on the
insulation! What voltage transforer are you using with that gap?

Jim, if your feeding that gap at 60 Hz and there is more than 0.1 amp
available, you are playing Russian roulet (sp.?)! Do yourself a favor
and use an insulated (fiberglass shaft) screwdriver! As far as I know
there is only one official death associated with a Tesla coil, lets
keep it that way!
