Hi John,
first: I am very sorry about your loss. Especially because you put so
much work into your equipment. But never give up. The moment we give in
to people like this we are no longer ourselves.
That's pretty good. I know some neon people who couldn't do a neck-down
that nicely. The
Hello neon john!
Up to your mouthing off again like you are the god of glass blowing!
Well, you might be! You are great! Indeed, in watching your videos, I
have never seen anyone else with your excellent talent! But that said,
not everyone can do what you do. This is something you are not

Hi,
If I were given the assignment today to make a machine to make tube
bases, this is how I'd proceed. First I'd find an old tube with the
same base. I'd cut it open and grind down the base to just where the
seal joint was made. That would result in just the base molding.
that is one
Recently we made some vacuum-jacketed cold cathode lamps for use in a
cold climate. A single 10mm evaporative getter was sufficient to pull
down a 25mm X 4 ft long tube to 10E-7 Torr.
Yeah, I'd expect that kind of performance. How did you measure the residual
pressure?

How exactly would you proceed making - say - 13 pin tube bases? You need a
lot of temperature for that and precisely formed tools. So far this is
nothing I can see myself doing in the near future. I know a person who makes
his own (borosilicate glass) sockets, I might be able to adopt the

They are approximately torus-shaped (donut / bagel) except that the
top and bottoms are flat instead of curved, and the sides are
vertical. They are inserted
Ah, i see now what you mean! You can se them really well on tubes like
Z566M , they are made of glass wich isnt clear, it has more like a white

That white color is there because the surface of the glass in z566m stem is
matte, it is not uniform - because the glass was casted into form.. This makes

Hi John,

At what temperatures? I tried 800C and no luck..
