I know that tweeking these coils is how we figure this stuff out, but
getting educated opinions doesn't hurt. I finally got to fire up my new coil.
6" O.D. sec., wound for 32", about 1000 turns
3/8" cu tube, spaced 3/8" for 10 turns
sucker gap
right now 30 nF 35 KV maxwell
14400V PT running @ 1800 W -125 MA
I'm not getting the performance I expect. Right now about 52" strikes.
I suspect the coupling may be a little loose. The first turn of
pri.is 1-1/4" from sec, and first turn of sec. is 2-1/2" above the
pri. Tomorrow I may try to find some longer nylon screws, and raise
the primary.
So what do you think, am I too loose? Should I bother doinng this?
