Ok Terry,

Im glad to hear that you think they will work.  I did a low power test with 
about 30% of the total spark gap set and was already getting about 12" 
sparks.  So i predict if all goes well, i should get at least 24", maybe up 
to 30".  And get this, its all in a 10"x10" base!  Its incerdibly compact!
When i have pics, i will post it to the list:)

Steve Ward.
