The wire Elecraft supplies is in the category of "Thermalese" which is
heat strippable, but if you get wire from an electric motor shop, that
insulation will likely be "Formvar" which resists heat and must be
mechanically stripped.

There are two very different kinds of insulation used on magnet wire.
One type, which I presume Elecraft uses, can be stripped with solder
and a sufficiently hot soldering iron. It's also fairly easy to
scrape off. The other, "heavy polythermaleze", or whatever it's
called these days, is practically indestructible. It has to be
stripped mechanically, and even that's hard. I think the copper would
melt before the stuff would burn. Unless you're planning to run your
toroids really hot, it's more trouble than it's worth.
