> Mike mentioned to use a solenoid shape for my primary. What is that?
A solenoid coil is wound around a tube or pipe form(like the secondary) as
opposed to a flat spiral coil.  You can of course, use a spiral, but for
smaller coils, it seems that the solenoid type is better(at least according to
what I have read).  I would choose one that is about 1/2 to 3/4 inch larger in
diameter than the secondary diameter.
