Re: [TCML] NE Ohio Coiling Activities.
WOW. I live 15 minutes away from you in Richfield. I have a very large
coil that is near completion along with many other high voltage things like
a resonant mot bank and a can crusher and even a pole pig. I am young, 15
years old and i have been into high voltage since i was 10. I have a couple
of sstc's that i am working. If you had a teslathon i would definitely be
coming.
