Indeed, I once opened a 50 cm B/W picture tube to make a lamp of it. I carefully packed the tube in thick blankets and then filed off the exhaust nipple. About one minute of hissing and the pressure was equilibrated. No danger at all! eric

But, unlike a picture tube, you could put internal support structures within the "tube" which would make it unnecessary to have really thick glass in specific areas. Then it becomes a matter of how you would glass-cast it and insert the cathodes. A 7-segment giant nixie would be relatively "easy" to do; trying to preserve the individually-shaped numerals (which in my opinion is what makes nixies so beautiful in the first place) will take some careful planning. BTW, if you have ever broken a picture tube, it's rather fascinating how thin the glass is towards the neck versus the outer ridge at the front. Which is why we always threw tubes on the ridge to maximize the BOOM....21FJP22's were my favorite. Breaking the neck is flat-out boring.. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
