Help! I'm Confused!!

After reading and sorting through lots of messages from this group and 
the usa-tesla group, and information that I have gathered from 
ftp://ftp.funet.fi/pub/sci/electrical/tesla/, I am confused.  The 
formulas that Bert Pool gave and some of the tables that Richard Quick 
gave for the resonant frequency of the secondary come out very 
different.  I assume I am doing something wrong when doing the 
calculations or I'm missreading  what the formulas are for.

Since I have been having a bit of trouble getting my hands on used neon 
xformers ( was able to get a 12kv 30ma so far), the power supply is 
still up in the air, but I am still aiming for an output of around 12 to 
15kv at 120ma.  If I have read correctly, the primary of the Tesla coil 
would best be made from copper tubing of the inverted conical shape.  A 
secondary coil of around 6 to 8 inches diameter, a couple of feet high, 
with Mr. Donut on the top. I would love to get one of the commercially 
made capacitors but by the time I could get it to Canada it would be 
very pricey, so thats still up in the air also.
