(I tacked the following onto a thread in the other forum and I think it's worth adding to this thread. If nothing else, this technique is prettier than five wraps of electrical tape and sturdier than five wraps of masking tape.)
For me, the need was to tighten up the old 3,7,10 and 12-inch CRT bases.
I’ve never been comfortable with using a “crazy glue” because it seems a bit irreversible in a situation where one might want to unglue it for one reason or another. Others have mentioned possible stress to the glass. Since they’re not making these tubes anymore – or the glass bottles, etc. – and with the rebuilding process having a questionable future – I don’t want to do anything that’s going to subtract by even one from the existing stock.
Here’s what I’ve done and I kind of like it. I use a single wrap of 2” transparent packaging tape. Done neatly, it’s almost invisible and – it’s reversible. It yields a very tight result with no likely stress to the glass. This might be better than the acetone-thinned nail polish that I have also used as a glue. The tape stabilizes the joint with a technique that is not hidden – what you see is what you get. (It would be even neater if the tape had a heat-shrink property to make the Bakelite-glass joint a bit tidier.)
But how long will the tape hold up under the heat emanating from the CRT heater or from the temperature environment of the cabinet? Ask me ten years from now. But any sign of failure should be obvious – none of the surprises you may get with a glue. Try it. You might like it.
