Trevor,

ok so basically every one that has replyed to you is right. when you open
your spark gap more you then let more of charge build up in your tank
cap before the charge can discharge across the spark gap. but since your
using salt water beer capacitors. your are not able to efficently charge
to a high enough level to spark across a bigger spark gap due to corna
brake down in the bottle. aka ... you either need more beer caps
to evenely spread out the higher charge,  or maybe a proper cap from ebay
or an MMC... but if u wanted to use the same kinda maybe try using wine
bottles if you got them or look into using other matterials or methods.

good luck.. be carful dont let the caps discharge to much in the bottle
thats how i blew my first NST

      i had the exact same problem as you did with spark length..
      and what i> did i was exactly as chiris said .. try varying
      the distance between the> electrodes.. this will send a

      change that value enough your also going to through> of your

      using?> Eg nuts and bolts ... or copper pipes or are you
