Hi Michael,
the numbers for nixi tubes is one of the problem I havent sufficiently
solved yet. Are your laser cutters able to produce numbers that have 0.4mm
wide lines? The material would be 0.1mm thick stainless steel sheet (316L).
I could send You some sheets to give it a try, just send me
One more thing - I would also provide the layout,

Im not sure, but i think you might be able to make the grid from multiple
horizontal wires that would be spot-welded together. Something like the
ZM1175 or ZM1210 have. It really depends oh how well you could weld
multiple wirest at once.

I use to work closely with the laser people. Use to cut stainless (316
304) down to around 0.010 (0,25mm). Should be able to do 0,1mm thick, but
cuts 0,4mm (0.016) apart, is going to be iffy.

I agree with threeneurons that cuts down to that distance apart are
going to be iffy.
I know that there are companies that laser cut solder stencils with
machines like I have, though, they might be using a different laser head
than the one I cut with.
So, Dalibor, I'll contact you offline with
Otherwise, is there anybody out there familiar with chemical etching
stainless?
Not much to it - it's like etching a printed circuit board. Coat with resist,
expose to pattern, develop, etch.
Places like Micro-Mark sell kits to do this:
Sounds good. And yes, other people that have made nixie tubes do seem
to be getting good results with the level of vacuum that you are
getting.

Also, I have all sorts of crazy laser cutters here. I may be able to
come up with a good stack of numbers or other characters if you'd like
them for your nixie tubes. I have never cut anything so fine with
these lasers, but according to the manufacturer, I should be able to
do it.
Cool. Let
Hello Jens,
pretty sophisticaed way of leak detection ;-)
what do You think by the insufficient greasing on my needle valve? The
rubber o-ring used to connect the valve to the system was not greased
properly? Or something else?
it is not airtight if the scale is adjusted to just zero - does it
I am not sure if the picture is visible, so it is attached..

Hello Michael,
10E-6 torr is not necessary. For testing purposes is 10-2 torr enough,
because then the tube is filled to somewhere around 30 torr what is much
higher pressure.. The initial pressure is not so critical in nixie tubes,
but influeces the total lifetime of the tube.. However it would
