Hello! Nice, I am glad You are really working on it, so do I :-) I am spending all my free time making nixies, not much time to write about it on blog.. I am now in phase of building glass lathe again, the previous one was of bad design..
I made several stems from Simax (boro) glass using a lead-in-wires with tungsten middle sealing part. I tested them on helium leak detector and some of them are ok! :-) So now I need the lathe to make the envelopes and seal it.. http://dalibor.farny.cz/wp-content/uploads/2012/09/IMG_8088.jpg I also did simple experiment with photo-etching of numbers from thin stainless steel sheet. It works, but the etching proces will have to be made more even and much much faster to prevent under-etching.. http://dalibor.farny.cz/wp-content/uploads/2012/08/20120804_120302.jpg I also had to build new transformer spot welder, the capacitor discharge welder waswaste of time :-( the new one can be adjusted, tungsten-steel welds are now really easy :-) Dalibor Farný http://dalibor.farny.cz sent from Samsung Galaxy Pad Dne 27.9.2012 5:17 "jb-electronics" <webmas...@jb-electronics.de> napsal(a): > Thanks Michel, I am planning to do all kinds of glow lamps before I get a > real torch, a real colon display would be nice. > > Next, I will experiment with the aluminum oxide insulator.
