Marc, all,

I'm certainly no expert on xfmr/inductor design, but it seems to me that these
things would be a nightmare for eddy current problems and get very hot since
thet are one solid piece of steel. I wouldn't imagine cast iron would have 
very
good magnetic permeability properties either (low guass saturation?) Does 
any better qualified individual(s) out there have any insight on this matter?

Good, Safe Coilin,
