Hi Hans and welcome to the Vacuum Experimenters Group. I think you will have a lot of fun building your NIXIE tube! You might want to check into one of your local NEON SIGN companies to see the

James, Thanks for the GREAT INFO... It's going to take me a while to digest all that and check out the links but it's nice to have on file here to refer back to! OK on your diff pump size... I thought

Hi I want to build my own nixie tube. I built a nixie clock you can see on my webpage, see http://www.hanssummers.com/electronics/clocks/nixie/index.htm. Seems fun to have a go at building my own

Hi James... Have you done any "fall-off" experiments to see just how much ONE FILAMENT will coat? The TV tube coating machine I saw would do a 27" tube with one filament approximately 15 inches away

What Size diffusion pump do you need / or how large is your chamber? What kind of gauge do you need --thermocoulple / Ion etc AGUSTIN GASPARINI <teveotron@...> wrote: --- RON WHITE wrote: Mr Ron

Ok Ken, here's one for you. A few weeks ago myself and an associated welded up a 25*25*11" ID steel box out of 1/2" thick sheet steel. Ordered 15 feet of 10mm O-Ring cord to use as a door gasket and

There just has to be someone doing something?! Let us hear about it! Ken Hunter

Hi JK... Thanks for checking in. I am putting together a resistive coater (when I find a home) and will no doubt have a zillion questions to ask. Usually when we ask a question though the responder

I would be interested to know if the guy has any historical publications or pictures that he would sell or lend to the Society of Vacuum Coaters for publication on the HISTORICAL portion of our web

I just met a fascinating guy who owns a small vacuum research company which dates back to the 50s. If anyone needs parts for old equipment he has a junk room full of Diffusion pumps, gauges power

Particularly if its for sale in Australia. Charles I just got lost in thought. It was unfamiliar territory.

Hello all, I have a NRC resistive coater that dates back around the early 60's. I have opened a part time business doing decorative coatings. I have been in the electrical feedthru business since 1989

I would certainly suggest using multiple vacuum pumps. A "roots" type centrfugal pump will get you started and then maybe a liquid ring vacuum pump then your pump should do the job. The new
