Hi folks,
just a small follow-up on my first glow lamp post: I have managed to
make a pinch seal using the 9mm tubing with four electrodes. The next
aim is five.
It is quite easy: all you need is very small glass tubing. Just stretch
9mm tubing, and if you do it fast enough (and carefully, of course) you
get very nice small tubes with diameters below 1mm. Then I just cut
these to pieces of 20mm and insert a Dumet wire each and heat it up with
a small handheld torch. Then I align four of these wires and use a small
portion of glass to glue them together. Then comes the pinching process
which is not so critical if you have ensured all the four wires stick
together good. Will document that on my website soon.
So now I have a glow lamp with four more or less parallel wires... Could
you call that a Nixie tube? ;-)

I also want to try to make evacuation pipe in stem, but there will be too many
wires, how do You solve the problem of wires on the place of the pipe? I cant
see that detail on your photo..
I'm curious too - that's a lot of wires for a pinch seal.
Do You think that original industry made nixies used photo-etched numbers and
anode mesh? Or it was stamped? You found a layouts or finished 5 and 7? This is
a part of mosaic what I still miss :-)
Instead of starting with existing nixies, I've been playing with generating
cathode graphics using computer fonts. This one is just a test, I'd probably
want to use
a lighter typeface for real nixie cathodes:
