Greg's Garage is an excellent high voltage site for tesla coils and other stuff. Without him, my high voltage section would not exsist. I got the dimmer switch/ignition coil idea from him as well. Goto his site - it is excellent and has some great high voltage pictures.
Jen's Tesla coil webpage
Not the biggest of coils (yet) but well written with good info
If you want to talk to me or other tesla coilers in the UK, go to the irc server irc.quakenet.eu.org port 6667 and the channel #tesla.uk
For newbies at irc that is '/server irc.quakenet.eu.org port 6667' then when connected '/join #tesla.uk'
If you need an irc client download mIRC
