Re: 3 phase coils

I made  a 3-phase JL back when I had a 3-phase 400hz generator from a 
military auction. Simply took off some primary turns on 3 old neon 
bombarders I got lucky and found relatively cheap and rewound the 
secondaries with kapton tape for insulation due to the higher v/t ratio. 
The JL was 3 rods instead of the usual 2 with 3 arcs climbing 
simultaneously in a delta configuration. As for the TC, got the schematic, 
but never got around to actually building it due to cost (requires 3x 
components- 3 rotaries on a  single shaft, 3 caps, 3 transformers, but they 
last much longer, since for 360 bps, each leg only needs to do 120 bps with 
each rotary turned 120 degrees relative to the next). Unless you're 
building a truely huge TC (50'+ sparks) where one leg of 200A won't be 
enough current, single phase does fine.
