Hi Dalibor,
I will take more detailed pictures today. My problem is that the needle
valve I use is pure crap... It is not even bellow-sealed. I was sure it
was, but it's not. See an image here:
http://www.jb-electronics.de/tmp/needle_valve.jpg
So I will get rid of it and maybe just use it for the air-inlet... Man,
I had really no idea about vacuum when I bought this. Stupid me.
I already have a pressure reducer matching my gas bottle with a 1/8" NPT
thread. Ron helped me a great deal: I already purchased a matching
compression fitting that will be vacuum tight (I hope) with enough
teflon tape. In the compression fitting I will mount a 6mm copper tube
on which I will solder 1mm capillary tubing, so quite similar to your setup.
I still need a connector to the KF16-system. I will go for a similar
needle valve that you use and hook it up to the 1mm capillary. But what
I really need is a connection to my KF-16 system in which I can screw
one of the 1/8 NPT threads from the compression fittings.
I have seen that you already have such a flange. Where did you get it?
Jens
Hi,
Is it a kf-16 to threaded hole connection? Send me photos and
description, I am making some parts for my system currently, so I
could make that for You.

Nice!
I am currently figuring out how to connect the Neon bottle to my
system, I will try one configuration tomorrow I guess.
Jens
Hello Jens!
It is rated as a high vacuum glass valve, so I guess there should
no measurable leak.. I greased it with high vacuum grease, rated
for 10e-6 torr. I bought it on ebay for 11 pounds from UK..

Hi Dalibor,
looks good! What is the leakage rate of the glass valve, I am
curious?
Jens
Hello guys!
I would like to share my excitement of todays
experiments! I was spending a lot of time on making
tooling recently, so another glowing something after long
time:
