Tim,

I ran some quick calculations on your coil.  It does look like it 
should turn somewhere between turn 8.5 and 9.0 on the primaryl.  Are 
you sure your capacitor is about .01 ufd?  Have you tried to increase 
the coupling by either lowering the secondary or raising the 
primary?  If this causes racing sparks on the secondary, back the 
coupling off incrementaly until they go away.  You indicate that you 
are using a sucker gap but what you describe sounds like a standard 
copper tubing static gap.  Do you have air flowing between the 
gaps?  What is the setting of each gap?  Do you have a safety gap 
that is properly set?  If so, you can open up the main gap (by adding 
sections) until the safety gap starts to fire then back off one 
segment.  You should be able to get easily two to three feet 
sparks.  If everything else checks out ok, I would suspect problems 
with the primary capacitor.

Good luck,

Ed Sonderman

hey all

i built :
sec: 3.3" x 20" 24 gauge
pri: 13 turns .25" tube, .25" spacing, 20 degree frm turn 1 to 13
topload: 18" x 4"
S.S.G. : 9 copper tubes (4 shorts for 4 gaps total)sucker gap
12Kv/60mA NST
130uf PCF caps
Cap: 2 1500mL wine bottles, 7 40 oz bottles.....total cap. size approx. .01uf
Variac

the best spark is 5-6" to gnd  and looks very "flybackish".....thin
and always 1 streamer...primary tap comes out to about 8.5 turns, any
where else there is nothing...the sec to pri distance is 1.5" radius
apart and sec is .5" above pri. first turn....any thoughts....wih a
12Kv/60mA i should get a little more, eh? i don't have a website,but
got a digi.camara & can email picts....
