magnet wire

[Jeremiah McCarthy]

The magnet wire that Mouser sells is heat strip-able (Beldsol insulated), but not all magnet wire is heat strip-able...The magnet wire RS used to sell was not heat strip-able...The insulation on this wire is called Formvar and is suited for high temperature applications such as electric motors and power transformers...It must be mechanically or chemically stripped...Heat strip-able wire would fail under the high heat conditions encountered in some electric motors, like in power saws...The commutator connections in these motors are not soldered, they are swagged...

A good source for small quantities of magnet wire is
Amidon, the toroid supplier.  They seem to be happy
to process small orders for experimenters and hams.

I think you would want the Thermaleze or the enamel,
but not the Formvar.

I just checked the wire I got from <http://www.qrpkits.com/magnetwire.html>
  IS heat strip-able.  800F works fine.
