The hole for the IN-18 exhaust tip is .250" diameter. Regards, Jeff On Jun 8, 7:46 pm, "A.J.

I have at least a dozen non-working IN-18 tubes, though none (that I recall) have broken nipples. Some have had seal failures around the pins, while I don't know what is wrong with others. Since the hardest part of making Nixie tubes seems to be creating the digit elements, I was fascinated by the "Audio Tubes" episode of the Discovery Channel (at least in the US) show "How It's Made" (season 9, episode 7). While they gloss over a number of the details, the equipment they're using is manual and rather low-tech. It would seem to be possible to re-use the digit elements in a whole new tube envelope. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.

I have only one dead IN-18 and the "pupik" looks OK. If it can be repaired then count me in. But I guess that one of the pins leaked. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.

Re: [neonixie-l] Re: IN-18 resurrection
Great idea. Ummm, I don't have any broken/gassed tubes anymore (since I took them apart, etc), but I will be willing to take/buy some tubes that were filled with a different gas (different color). I want purple or blue. :) The only tube I have left (broken) is a B7971 (looks like it was shot with a BB) - small hole through the glass. Michail In a message dated 6/7/2011 3:58:41 P.M.

Re: [neonixie-l] Re: IN-18 resurrection
Nixie Gang, Am I to assume that nobody on the list has IN-18s with broken nipples (judging by the response)? Should we give it a few more days for folks to chime in? To reiterate, I was hoping to get a pool of people, so that we could collect all the damaged tubes and have one expert do something very interesting with them. Margaret sounds very knowledgable, and I don't know about the rest of you, but I'm going to ask her fill my broken tubes with pure argon. :P -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.

Re: [neonixie-l] Re: IN-18 resurrection
I have my one tube, that's it. I could go for having it filled with argon just for grins, I'm concerned that the nipple on my one bad tube may not be broken, it may have lost seal some other way, like one of the cathode or anode pin ports.

Re: [neonixie-l] Re: IN-18 resurrection
Meredith ( www.6smith.com ) suggested there is a special epoxy. Quote: " If you just want to temporarily reinforce a seal, there are high vacuum glass to metal epoxies such as Celvaseal which may not have much longevity, but can help you troubleshoot the problem." Might be a product of interest to those who observe their tube just starting to lose gas (dimmer glow, and partial and "traveling" cathode discharge). Perhaps an application of this sealant would stop the loss, and voltage/current to the tube could be increased to compensate for the fainter glow. > >I have my one tube, that's it.

Re: [neonixie-l] Re: IN-18 resurrection
I think that particular tube may have had just an overly large nipple, that's all..haven't had any problems with the other tubes in the clock after removing them and replacing them (matching tube heights).
