And, just out of curiousity, how would one go about winding a
torroidal transformer?

Assuming you could obtain a toroidal mains transformer core (those ferrite
rings are not the same thing at all) you would have a nightmare trying to
wind it. They are factory wound using a long thin spool holding the
enamelled wire which is fed through the hole in the middle of the toroid
over and over to get the right number of turns. You'd have to be a very
determined hobbyist to build a toroid winder in the home!

Unless, of course, someone knows another way of doing it...
