Mike,
Your coil performed about twice a well as my first one did, with similar design properties. I had the pvc 1" by about 36" pipe, a Morton salt container for the primary, a metal toilet float for the topload and a capacitor made from about 10 coke bottles sitting in my moms soup pot, salt water, coat hanger electrodes and all. This was back when you could get 16 oz bottles made of glass. I got a dazzling 2" display of corona from my 15/30 nst. Must not have had something optimized..... :-)

This very article started my coiling back when I was 15. I then was under
the false impresion that voltage gain was simply a matter of turns ratio. I
wound a 5 ft. tall sec. on a drape rod tube no more than 2" OD. The primary
was wound on a cardboard Quaker Oats canister. I got about 9" sparks from a
15/30. For about 35 years it sat dismantled in my folks basement. Last fall
my brother in law deciced to clean the basement, and threw it away. Being
very hurt, and angered (it took a whole summers cadying for money, and the
following fall/winter to hand wind), I went on a quest to learn how to build
another one. Well  a year and a half later, I have 2 rockin' coils doing
respectively 4', and nearly 8 foot sparks, and a huge coil in the works, I
hope to get over 15 footers out of. THANKYOU BROTHER IN LAW!
