There is a good book on this:
> EXPERIMENTS WITH ALTERNATE CURRENTS OF HIGH POTENTIAL
N. Tesla, available from Lindsay Publications, order# 4392,
$ 9.95. See my Tesla References file for Lindsay's address.
There are also three or four other books listed in the Tesla
References post that include sections on experiments.

This particular coil is not the best example of a Tesla coil, it
works, but it also has some problems. Try standing on a well
insulated platform, hold a section of copper pipe firmly in your
hands, and bring it gradully to the discharge terminal. You
should not get bit too badly. With the coils that I build and
operate (using a dedicated RF ground for the base of the
secondary) the voltage from the top of the coil is very clean RF.
I can pull several feet of hot spark to a metal rod in the
fashion with only the slightest discomfort.
... If all else fails... Throw another megavolt across it!
