Frankly, I have NO CLUE how the heck they did it in the factory!
My guess for a modern day rebond:
Use a suction cup hloder to hold glass in front of CRT at right sapceing. CRT held by jig.
Wrap tape around the two as origional.
Poke two holes in top - one to let air out, one to add sillicone.
Fill with the new stuff - slowly.
Beyond that? No clue.
I'd hang onto any bonded tubes with bad bonding - they inevitably test great, and let's face it, SOMEONE will SOMEDAY figure this out...

my guess is that those sheets of silicon were pre-manufactered and heated just enough to create a bond. I cant imagine that they would have poured silicon on each individual tube. The sheet that I removed was too perfect for that. Pretty good process for back then.
