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.
