My names Curt and I've been trying to get a tesla coil up and running for a
while now. I've used multiple power supplys such as four mots wired in
series parralell with a center tap ground but they did not last probably
due to being used for fractal wood burning prior. I have tried NST's but
they had the gcfi on them and only worked for the first few minutes. So now
I've moved onto a cathode/anode 80 kva x-ray transformer that feeds through
a bucket capacitor and into a bench grinder with a 6inch plastic fan wheel
that I wove solid copper wire through four of the fins and have a oil
burner point on with side for the pick ups. My primary coil is 9/16" x 1/8"
solid copper ribbon with 1"spacing between coils and my current secondary
is 4.5" pvc with two recycled 34 guage magnet wire soldered together and my
top load is two old chevy hubcaps hot glued together. I'm running a 30amp
variac 125v ac to regulated 125v ac and I can't get past about 30v with out
the fuse blowing. Just when the rotary gap starts to fire the fuse blows.
I've tried a mot with secondary shorted between the transformer and the
variac but it didn't seem to make a difference and I've tried a250 watt
15ohm resistor first where the mot was then tried it between the
transformer and the primary. Both places it just heated up and would not
allow any spark at the gap. Any help with the wiring on the transformer or
variac or suggestions would be greatly appreciated! Thanks in advance.
