[Elecraft] stripping insulation from enamel wires

[Charlie T]

It depends on whether your wire has "enamel" or "Ny-Clad" insulation.
The darker enamel can be removed with a "paint-remover" like stuff that was
sold in in little square bottles by CG and others.
A quick search failed to locate any here, but I've got some somewhere (??)

The lighter color stuff is probably Ny-Clad and will have to be sanded, or
scrapped off as the enamel remover won't cut it.

I find that some 400 grit paper with take off most insulation without
damaging the wire as can happen by scrapping.

Subject: [Elecraft] stripping insulation from enamel wires

Here's an old problem that I've never solved: how to strip the enamel
insulation from wires for winding toroids.

The instruction say:
-dip in a solder pot which I don't have
-use a soldering iron to, presumably, burn the insulation off which has
never worked for me.

Leaving soldering pots aside, the hot iron approach has never burned off any
insulation even with tip temp's hovering around 1000F. Just doesn't happen.
Maybe it's the soldering iron, maybe my method, but whichever, the enamel
insulation just sits there. I end up using a file to scrape off the
insulation which is tough on the wires and hard to predict when enough is
enough. Any insightful hints? Thanks much.
