Micro coil

Hi all,

Just assembled a mini really microscopically tiny TC. Here are the specs:

4kV 9mA bug zapper transformer, repotted in petroleum jelly
1 15oz Salt Water capacitor
7 turn helical primary, tapped at 4 turns
.5 inch cardboard form wound with hair-thin wire(not sure of the gauge, 
maybe 36?),
4 inches wrapped by hand(really hard) No crossovers in the windings.
Spark gap is two copper electrodes set at 1/32in

Performance is OK. 1" sparks to my hand. 3/4in streamers. I do not have a 
good RF ground in my room so I attached the bottom of the secondary to a 
heap of Al dryer duct leftover from making toroids. Works fine for right 
now. I will take it out in the garage and hook it up to my RF ground. I'm 
also planning on building an MMC for it with some ceramic caps that I 
ordered. The SW cap isn't anywhere near res.

Does anyone else have a microscopic coil? Questions? comments?
