Wow, great tip about the aspirin! I'll try that on my next transceiver
build. :)

Enameled wire is pain to strip mechanically. Back in my school days we
used a pill of Aspirin and push the end of enameled wire shortly onto
it with hot solder iron. Aspirin would melt and eat away the enamel,
easing the tining process. Fumes are not nice to inhale, though.
@Gideon if you prefer protoboards, you can try kynar wire. A 30-gauge
spool of it is not expensive, strips off easily and solders even easier.

Yes, but why use enamel coated wire in the first place? I've only
ever used it for winding inductors and transformers. I hate the
stuff. Dipping in molten solder usually works to remove the
enamel, with a clean-up pass using sandpaper.
My favorite protoboard wire is the old 80-wire PATA ribbon cables.
In Seattle, I can buy the ribbon cable for $1, giving me quite a
bit of good wire for the price. The wires easily separate with
fingernails and the insulation easily strips with fingernails too.
Avoid the 40-wire version, those use stranded wire instead of
solid-core.

For any diameter of enamel-coated wire larger than a strand of
hair, the burnt enamel should be removed to expose the copper.
Otherwise solder wetting will be poor and the soldering
process frustrating.
You can do this using fine sandpaper, a file, or a sharp
knife. Burning the enamel first makes removal easier. For thin
wires the soldering iron is adequate. Larger diameters require
a lighter. Even large diameters a small blowtorch. Tin the
wire prior to soldering using a generous amount of flux. This
will also show you if you did a good job scrapping off the
burnt enamel.

Well the first board is filled with tubes, and my head is
filled with headache from peering at the board.. The
enameled wire was very hard to solder even after burning
off the enamel layer. Although I do not dare to show the
abomination that I call "soldering" the tubes are all
connected. Don't worry I know how to solder, but the
enamel wire was giving me a very hard time. The nice thing
about the enamel wire was that it was easy to go through
the forest of component legs. I'm off to bed.
