I've heard of people using inductive ballasts to vary coil power. THats 
certainly what I plan to do with my first coil. I understand that one 
method is to take a microwave oven transformer, and look for the weld 
between the e shape laminations and the I shape laminations. grind the 
welds on both sides off with an angle grinder and then hit where the welds 
were on both sides with a large chisel and hammer- i use a stoning chisel 
and a 2 pound stoning hammer. the transformer will break apart nicely :) 
then you can add spacers between the halves, and shorting the secondary 
vary the thickness of the spacers. I've never tried this so I have no idea 
if it works; maybe another member could verify this or tell me i'm an idiot 
as appropriate :)
