When I was about 15 I wanted a several Killowatt supply for my Tesla
coils and couldn't find anything close so I got this idea of making a
transformer core out of iron wire
used in the construction industry (in concrete work) it comes in boxes
about 3 feet
long and may be 4 by 4 inches packed dense with about 18 to 20 gauge iron
wire. I heated the bundle of wire in a charcoal fire and allowed it to
cool very slowly to aneal the wire. I then bent the wires into a square
shape and alternated the sides that the ends came together on. I wraped
the whole deal in several layers of electrical tape and wound my primary
on one side and the secondary on the other. I managed to get a fairly
nice although very bulky transformer that gave me 3 killowatts at 18KV on
the secondary.
