aaah, no, that won't work. at 60 hz you need an iron core. 10AWG will
carry quite a bit of current - about 50 amps if I remember right (steady
state). you would be better off gettting a cheap commercial transormer and
modifying it - or find a used variac

Is it possible? I was thinking take a piece of 12" thickwall PVC pipe,
about 6" long, wrap #10 enamel coated wire around it in the standard variac
fashion, and machine up some kind of rotor/brush assembly. Would this
work? Any special considerations? What kind of current will 10 AWG wire
handle at 240v in that application?
