How about a pinch seal with an inline row of wires? I've only ever made those with two wires, but I don't see why it would be that much more difficult to put 10+ wires through with an appropriate jig. Induction heating is easy, I built one of those a while back that I use for other things. As for the ceramic spacers, would glass work? I know you can get small glass craft beads, I can't say I've ever looked into it though. The glassblowing is the hard part, I can do a reasonable job of splicing and bending neon tube but even after much practice it's very difficult to get good consistent results.
The B5870 tube would be a good starting point for a design using a pinch seal. It has a zig-zag row of wires in the header, and the bottom of each digit is spot-welded to its wire, with no spacers or connecting wires needed. There is a single ceramic block at the top to hold the digits in place.
After all, if you're trying to make it yourself, simplicity is valuable. -- David Forbes, Tucson, AZ -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
