David,

Yes, I'm using a discharge pin protruding 20 mm horizontally from 
the 1" x 5" toroid. The clearance between the uppermost turn of the 
secondary and the toroid is 20 mm. I had to use the toroid instead 
of a 2" dia sphere because of heavy corona (having burnt the PP 
coil form already) from the originally added space wound turns 
which I've removed in the meantime.

- I know. And the big 3 phase tranni from the russian mobile radar 
wants to bite as well  ;-)
