"Kevin,

What you just described is not a Tesla coil.  A Tesla coil is an
air-core resonant transformer.  You are talking about a simple induction
coil.  In other words a big ignition coil.  If this is what you want to
build then round up a couple ignition coils and build the circuit on my
page.  There is also another possibility,  a relative to the Tesla coil
is the Oudin coil.  It uses low voltage 120-240VAC to charge a capacitor
and it has electromagnetic breaker points that act as a sparkgap would
on a Tesla coil.  When the points are closed the capacitor is discharged
into the primary of the Oudin coil and an LC circuit is formed.  The
secondary is resonant at the same frequency as the primary is
producing.  This is very similar to a Tesla coil.

	In Martin's book there is a good construction article on a
really man-sized coil of this type.
