	I am trying to adjust my built Tesla coil's spark gap to the perfect
setting so as to make a more permanent and efficient series spark gap.  I
tried increasing the gap width, and the discharges seem to have enlarged,
except the coil does not turn on until the Variac is at about 90 volts.  If
I am not mistaken, I would assume that that would put a lot of stress on the
NST.  The gap setting is a bit more than 1/4" I believe.  At about what
point should the spark gap begin to fire?  Thank you.
