I spent some time on the leak detector recently. There are two fans, AC 230V, one for the diffusion pump, one for cooling the electronic box. Both started to make loud noise, so I had to replace them. I was surprised that the new fans are absolutely identical to these original 30 (or how many) […]

I started to build gas filling manifold, the previous solutions were not satisfactory 🙁 This manifold should have these features: all parts brazed together (by AlSi compound) kf-25 flange connection baratron connection evacuation tube connection valve for fine control of neon valve for fine control of argon valve for fine control of vacuum, when the […]

I have just finished first chuck for the glass lathe. The last part – worm holder – turned out to be much more easier than I had originally thought. I just drilled a hole into U holder cut (laser cut), cut a half of the hole and got a groove for the worm axis. All […]

The high pressure valves from eBay finally arrived yesterday. The seller dailyappliance2010, item number #290804664389. It is not intentionally a vacuum valve, but as Ron reffered, this valves should be leak tight, at least for the purpose of filling the tubes with gas.. I bought two brass adapters with hose nozzle on one side (hole […]

I am waiting for some stuff to come from US before I can continue building the inert gas manifold.. So I brushed up the parts of the oven for baking the tubes and made some progress on it. I found some Promasil fire-resistant boards in a local shop in 50% sale, perharps Christmas sale 😉 […]

The chuck is now mounted on the spindle, also the worm gears are now ready.. I wait for the jaws to be cut on the laser..

I made an idler pulley tonight so I am able to finally try turning the chuck!

I have almost no time to spend on nixies recently (moving to new house, newborn twins..), so there are some photos of my previous work.. It is mostly preparing of tools for work in the future.. A glassworking torch, oxy-gas..

At the beginning – I would like to thank to Ron Soyland, I would not be able to get it work without his great help (hundreds of emails) and his extensive knowlege. Thank You Ron! When I bought the machine, I thought I will just google and download a manual for it. But it eventually […]

I am step by step disassembling all the helium leak detector I bought recently. There are several things to do.. cleaning the flanges, replacing the o-ring, checking the oil in pumps.. Ron Soyland mentioned that he disassembled also the spectrometer unit to check the filament state, so I decided to do so as well. The […]
