Martin I think I could make enough voltage, I slapped a ridiculous amount of voltage out of a coil before, 6" of ionizing spark should be enough to get through the insulation, I cought a zap from it too one time, damn! left a pinhole burn, and I'm sure I could make even more voltage if needed, run 2 ignition coils even, step it up twice from a capacitor discharge of about 300v, I love HV.. lol my buddy's dad does neon signs, has an old transformer from an electric chair, uses it to draw the gas through the tubing, that thing is nutty, standing it the same room while he arced it to the table about 2 feet away made my hair stand on end... mmm..
