Well my first try at a coil worked a little. It is 15Kv 30ma NST and the 
first try was at 8 ½ in.  I do have a question. Should the bottom of the 
secondary coil be even with the primary, above or below it?
  I had the torrid up too high at first, I had to bring it to where the 
lower side was just below the top of the secondary before I got any sparks. 
The torrid is 4” flex pipe mounted on a 12” x .032 alum plate, overall 20” 
dia.  Are there any hard and fast rules on setting the torrid?
