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

I've been following this discussion for a couple of days now, and thought I
knew what was going on, but I just went to my bench a physically put my
hands on an IV-6 VFD tube. The filaments for these tubes are specified at
0.85-1.15 Vrms (nominal 1V), with a current draw of 50 mA. Note that
Put a new battery in your calculator: 1V/0.05A = 20 ohms
Don't feel too embarrassed. If you look at the old Yahoo nixie forum, I
have a long trail of on-line oops's.
Your hot resistance measurement procedure is correct, and that's what's
really important.

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
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

Oh - duh! I think the rest of the discourse was correct. (Sadly, no
calculator was used - I guess it's my brain that needs the new batteries...)

I have a vague feeling that enamel wire fumes are fairly toxic, hence I
used to sandpaper them first to remove most of it prior to a roasting with
a lighter. My workplace used to have an enamel wire stripper, which was a
funky bit of kit - 3 blades that spun round :-)

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
