[Elecraft] Stripping toroid leads

[Scott Ellington]

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.
