Subject: coil spark size???

hey guys I am  just wondering if the spark size that I am getting is about
right these  specs

spark length max 12 in but at the same time there is about 7-8  smaller
sparks ( I am wondering if that is because of my toroid  size)


specs about 600khz coil height is about 20 in primary is an  inverted cone
tapped at about 5 turns primary cap is .01uf home made using  polyethylene
and tin foil. you know the stuff I can afford in high  school

transformers are 2 23 milliamps 10,000 v OBIT transformers wired  in parallel
soon to be 4 of the same in parallel

spark gap is 2  bolts separated by under a 1/2 inch on the blowing end of
my dads shop vac  I am on vacation so I probably will repost this with more
accurate specs  once I get home





I don't think anyone has mentioned this yet, but if you have not already  
fried one or both sides of your transformers, and/or blown up your cap, cut your  
spark gap to no more than 1/4-inch. A good rule-of-thumb is ~2 KV/mm.
