The way Sperry/BAe used to do it (I assume they still do, but don't work
there now).
Use a methylated sprits (not sure of name in US) burner to remove the enamel
- keep it in the blue part of the flame (the hottest and no soot) and it
should come clean. Use a light rub with emery paper if you think it might be
tarnished. Then tin.

I'll ask some club colleagues this evening if they have other methods.

In the UK domestic radio & TV industry we used to strip and tin Litz
wire by heating it over a methylated spirit burner to red heat and then
quickly dipping the wire into a small container of methylated spirit.
This will likely work with enamelled copper wire.  A word of caution
though, this procedure makes the copper very soft and likely to break
before it is tinned.
