Hi, all...

I have been thinking lately about the relationship between spark length and
voltage. current isn't a factor is it? for example, 12kV can jump about
half and inch, and 1MV can jump, (guessing here) two yards? I was trying to
figure out an equation to find max. spark distance by voltage, but haven't
been able to do so. Someone had to already find it, and I'm probably just
re-inventing something, but hey, its worth a shot...

Also, I need some guidance on making a primary. It will be a flat spiral,
using Greg's design with the 7 pipes... I just don't know how many turns
I'll need. I have a 12/60 NST, MMC will be 11x2 .1uf GG (ggek group), and
static gap... Is there a simple program to determine turns, and tapped
turns? Also, I don't know if anyone replied to my post about the
double-tapped primary, or if i accidently deleted it :-( ... but I'll
re-post...
