hmmmm...     trim down the coil to around 24" of wound material  ( what is the
size of wire you are using ??  is it  20 - 24 awg? )  give yourself an
additional 3 " of exposed tube above the windings    and about 2" below the
windings...

the primary ....    if you have a single 15KV NST   ( what is the output
amps???    .030  .060   .090 ???  )  try tapping in at  turns  6 - 10   altho
keep the full 18 turns available for future use ...


the cap sounds useable ....

make a safety gap if you dont have one,  ground the bottom of the secondary
well to a seperate ground other than the house ground...


and make the toriod about 4" X 18 - 22 "  and put it about 3 - 5 inches above
the top of the upper windings of the secondary...

this should get you closer to 24 " of spark  ( i like to call them streamers
;)   )
