It's simply a matter of taking the time to reinvent the wheel.
The optimum materials for a transformer core are not the sort of
thing you can get at the neighborhood Wally World. High silicon
transformer steel is pretty much used for -- well --
transformers. It is a real b*tch to work with -- hard as knife
blades, brittle, and it's murder on cutting tools, not to mention
your hands. I know -- I tried to make some custom solenoids in High
School out of old tube TV power transformers. Ruined several sets of
aviation snips in the process, and ended up with lotsa pieces
resembling potato chips with razor blade edges. Shoulda bought them,
but didn't have access in the pre-Internet and pre-eBay days.
The design and construction of the windings in not trivial, either.
Sizing the windings, and spacing them properly to simultaneously
optimize magnetic efficiency, heat dissipation, and high voltage
integrity has preoccupied flocks of mechanical and electrical
engineers at GE, Westinghouse, Allis-Chalmers, and others for the
past 120 years.
With Dr. Resonance offering complete, tested and really pretty pole
pig units for the cost of 20 hours of minimum wage labor, it just
doesn't make any economic sense to try to roll your own, even if you
could get the materials for free. It's actually kinda amazing that
he's selling them completely restored and functional for little more
than the salvage value of the copper in the windings. You might want
to pick up a couple of them while they are still available to a

I have a question that I have wondered about for a long time and perhaps
someone can comment on it. How difficult is it really to "Make" a pole pig
or a transformer of some kind? I mean, why can't we wind a core, put it in a
bath of transformer oil and put it to use? Huhh, huh? Any xfmr guys out
there have an idea on that???
