My goal would be to design a transformer at 120 volt / 15 amp input. The 240
volt lines are such a hassle to set up when moving the Tesla coil around and
it would be beneficial to me to make a xfmr that would be as potent as is
obtainable from a wall socket. I work at a sheet metal shop so I should be
able to have the core sheets punched out to any dimensions that I decide to
design. Maybe some one out there might be interested in teaming up on this?

The process is very labor intensive. To wind a
240 volt to 15,000 volt transformer the primary
will require about 440 - 500 turns of 8 AWG wire.
and the secondary will require about 30,000 -
31,250 turns. The Iron core has to be sized
correctly for the amount of current you plan on
using. It will be hard to find. I actually have a friend who wound one.
