Hi Dalibor,
Are you calculated cost of manufacture of tubes?
Best regards from Barcelona

Hi Michel,
You are right, I am also eager to it glow. As soon as the shed is
built, I will move all the stuff there and start with it.
It should be a replica or copy of z568m, so the size of the numbers is
5cm. I actually dont have any z568m, so other dimensions are measured
from z566m and scaled. Isnt there anyone who has faulty z568m to cut
it open? ;-)
With the gold plated stainless steel - You actually jumped ahead, I
have this idea with the anode electrode (grid), that will be possible.
The numbers must be made of steel as all other metals sputters a lot
more and the life of the tube would be short. It would be possible to
make it also from brass, but the pumping time would be many times
longer than with steel because it would be done with low temperature -
I guess 100C instead of 450C. Once the tube is filled with gas, the
brass should not relieve zinc as the vapour pressure of zinc is small
enough. Zinc starts to cover the glass envelope at pressure of 10-6
torr and temperature of 200C, conditions during the bakeout process.
bye!

Beautiful work Dalibor!
What is the size of it? Looks like IN-18 size?
Can't wait to see them light up, you too I guess :-)
The brass really looks stunning and stands out between any other
nixie tube, it's a pity that you can't make them like that. Would
9k gold work, or gold plated stainless steel?

Hi guys,
I am posting some info about the process of re-inventing the
nixie tubes.. I made first test assembly from etched stainless
steel. Making a real nixie tube is difficult task, but I think
there is nothing what could not be solved!
You will find brief description here:

Thanks!
