Hey, so I FINALLY got my tesla coil working... wow it has been a 
long, long time trying to get it working, but im only getting about a 
6 inch spark to my secondary ground wire.
Here are my specifications
-2KVA 20A variac
-500-800mH (i dont know exact inductance) ballast
-15A circuit breaker
-4MOTS immersed in mineral oil
   -pri --> parallel
   -sec --> series mid point ground
-multi static spark gap (series)
-~30nF saltwater cap (parallel)  (assuming 28 bottles)
-safety gap to ground
-47mH primary 11 turns 1/4 copper tubing
-3"   18000 (dont know exact) mH secondary  ~1200-1300 turns 26AWG magnet wire
-15" outer diameter  4" diameter aluminum ducting toroid

So i turn it on and put variac full power, and I get a shorter than 
expected spark gap firing and when i bring my secondary ground wire 
to the toroid i get only 6" maximum streamers.  I tried tuning it in 
close to every place but the place that yields the largest discharge 
is the 10th turn.  I also put the spark gap in parallel instead of 
the capacitor but saw no real imrovement.  I dont know whats wrong 
concidering this is my first coil, but perhaps everyone here who has 
the expertise does.  Help would be very much appreciated, thank you.
