Hi Bart

    I think this coil has only average performace . I've read of 
coilers getting as much or more spark from much less input, but here 
are da specs:

Power: 1.5kva,single bushing  baby pig (piglet ? ) run at approx 3kw 
with homemade ballast

Caps: TCBOR rolled poly in oil ,approx .028 mfd

Pri: 1/4" ccopper tubing , 12 turns total, taped at 11.25 turns 
,(first turn  1.5" space from sec. coil)

Sec: 4" pvc wound with # 26 wire ,23.5" winding length ( first turn 
and pri coil  even hight)

Gap: Static type,1" copper pipe ,cooled by two muffin fans

Top Load:  four 8" steel balls , outer most edges at 26" apart

Max spark length:  Unknown ,. 5'   ???

I did try a rotary gap months ago, output was better, but didnt run 
very smooth, had some secondary breakout/racing arcs , I did shock da 
wife though  :-(    , need more testing in this area..............
