 My thought at the moment is to use
 long coils on 1/2" by 8" ferrite rods, with lots of turns of
 closewound enameled wire.  Think will provide the inductance and
 the high voltage insulation, while enough turns will take care
 of core saturation.  Have been looking at the local stock here
 and intend to give it a try when time permits.  As far as the
 voltage is concerned, I think a long winding will work OK, but
 want to check it out because ferrite has a very high dielectric
 constant and there may be unexpected problems because of that.

 Ed,
        I my TC, I'm using half of a flyback transformer core, it's about
1/2" in diameter and 4" long U shaped. It's closewound for 2" with 22 gauge
magnet wire. I don't get turn to turn arcing, but, I do get arcing from the
first and last contact points of the wire to the core. I'm going to try to
insulate the wire from the core to stop the arcing.
