Secondary ?



    I have my coil up and running. 
The specs. Are        3" by 12" secondary.
              10" of #24 wound on a 12" form.
              Primary coil is 8 turns of striped coax cable. 
              MMC arrangement of 2 strings of 10 Panasonic caps rated 1600 V 
      0.056uF.
              Powered by a 12000 v 60 ma NST. 
    Remarkably I'm getting 16" 20" sparks off a small torpid of spun aluminum 
about 2 ½ " by 6".
    My question is, I have an another secondary already wound it's 4" by 
about 40" with #20 wire at 30 turns an inch. I know that 40" is to long. So 
how long should it cut the pre-wound secondary down to? I'm guessing about 
25"?
Thank you all for all the input,
Leslie
