If they tend to go up why did you make your secondary 32" long?
Why wouldn't you have made it 17" tall?
The arcs would still go up, right?

If not then how do you know at what length they would go up and at what
length they would tend to arc to the strike ring?

Thanx

Hi Luke
The larger toroid above tends to aim the sparks upward and helps prevent
arcs to the primary. To see with and with out the smaller toroid see:
http://members.iinet-dot-net.au/~pterren/tesla_coil_sparks.htm#6%20inch%20co
il%20(the%20best%20ones)
(all one address)
The toroid E field tends to direct them up. My 6 inch coil (on the same
page) puts out a max spark of 96 inches from a 32 inch winding (i.e. a 3
times ratio) and never strikes to the primary with 2 toroids.
Cheers

ps "bare with me" sounds indecent.
