I seem to recall, from IIRC a very long 60's in house RCA promotional film(or perhaps an episode of 'How it's Made') of what they did then, a scene of a monochrome electron gun being assembled where they stacked all the metal parts on a temporary alignment frame then applied the soft heated glass to the element tabs to hold all the elements together as opposed to welding the elements to tabs on the glass like RACS does.

This method might also be useful in gun rebuilding. If only the elements that need to be worked on can be melted off or out of the glass rods(or the rods cut and new glass melted on in the appropriate place with the new elements in position), and then melted back in it might be simpler than all that welding.
