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.....    :-)
