I have done some work on my coil since I have last posted, and I have found 
my problem.  I think my tank cap is WAY to small for my MOT power source, 
which will soon be a 4 MOT stack.  I have calculated (from 
http://home.earthlink-dot-net/~electronxlc/tccalc.html) that my tank capacitor 
should be 200nF at 8kV, 650mA, not 13nF.
I would like to make sure that this is indeed a good tank cap size, so I 
don't go and make a huge poly capacitor for nothing (actually 3 in 
parallel).  Or would another type of capacitor be easier to transport/make, 
or cheaper, or better?

Needless to say I will need a very large topload, I was thinking about a 40 
inch toroid on top of a 24 inch toroid, for a total secondary capacitance 
of 77.6pF, with an inductance of 19.6mH.
My primary inductance will be very small, however I have found that a lower 
primary inductance produces brighter sparks that are slighly longer.  I 
will have 2 series static sucker gaps, until I can get a rotary gap.  More 
on my coil here

Are these good values for my 4.5 inch coil?  I expect a major increase in 
performace over my 12 inches of spark so far, but will they be around 
optimum values?

Thanks!
