I agree. It's only when I've tried running short secondaries at high
powers that the coils fail and arc uncontrollably along the secondaries.
When I did the experiments with the #34 wire on a short 9" secondary,
I was able to get something like 22" or maybe 25" spark length I
think before things got unmanageable. Later, I tried using #24 wire
with thick PVC insulation, (on a different coil), and it arced badly
along the 17" tall secondary when giving a 40" spark are so.
Bottom line, the secondary breakdown depended mainly on the
secondary length versus bang size, rather than on the insulation
thickness. Just making these secondaries a little taller stops all
the breakdown along the secondary.
