Mike -

WOW!! Eight-foot arcs out of a 120ma NST powered system is extraordinary performance, almost unbelievable. With a conventional spark-gap coil, this level of performance is usually obtained only with an over-driven potential transformer or a pole-pig.

Can you provde the detailed specifications for this coil? I'd sure like to try to duplicate this coil with my pair of 15/60's and see if I could obtain this performance level.

Dimensions of primary and secondary, MMC cap details (make & model of caps used, caps per string & number of strings used, total value, etc), toroid size, resonant frequency, details of the 240 BPS gap system, etc, etc. would be GREATLY appreciated. How much current was this system pulling from the 120 VAC outlet? Sounds like this coil is one for the record books. Certainly some photos are available? I'm sure that Terry would be happy to post them at Hot-Streamer.com.

What type of wound was produced when you got hit by the 8' streamer? Must have been pretty severe to leave a "nasty" scar years later. Did you require immediate medical attention? In 20 years of following Tesla-coil related subject matter, I can't ever remember a report where a streamer hit caused an open wound, so those of us with medical interests would appreciate the first-hand details.

Also, where did you obtain your 30" lawn-ball ornaments, and how much did they cost? These would be very useful for anyone building a Van de Graaff generator, and spheres this size seem to be extremely difficult to find.

I once got hit in the shoulder by a 15/120 powered coil a few years ago when I switched from 120 to a 240 bps and a better mmc and underestimated the length increase (~4 to almost 8 feet, with the spark going from thin and blue to alot thicker and white). Left a nasty scar at he strike point. My big toe where it exited to the deadman switch still feels funny (more like doesn't have much feeling). Contact was probably an eye blink long (thanks to the switch), but forget the skin effect (common belief of the time), I felt every beat of the spark gap and that hurt like heck.

"Was thinking of using 1 of those 30" steel ball lawn ornaments I have lying around to
make one whenever I can find some suitable 4-6" pullies (aluminum and
teflon hard to find), just don't wanna kill myself when I go to do
the hair-standing stunt."
