Awesome job! That's one nice looking set! And it looks like the picture is perfect too. Great work!

Never done cataract surgery before, but I understand the concept - heat the bonding agent, separate safety glass, clean, reassemble. One thing I was wondering about though - how 'structuraly sound' is the picture tube with the safety glass removed? Obviously they put the glass on there for a reason, and I know that it generally has something to do with implosion protection. Most of the tubes I've worked with have "Integral Implosion Protection" - i.e. that metal rimband around the outside of the tube. Having never gotten lucky enough to find a roundie color set to work on, I've not seen how the tube mounts into the set, but do the round tubes have such a band? I know the real old round sets (electrostatic B&W) just had a naked glass tube sitting in some sort of a rubber gasket or mount - what about on a round color set? Does the tube have a band with mounting bolts, or is it also a bare glass tube, hence the need for the safety sheild? In other words, is the only thing stopping the tube from going *fwooomph!* the safety glass, or is that just stuck there as an added layer of protection from things thrown at the TV, little kids, etc. I once read about someone trying to cut the rimband off a modern 27" tube for some purpose, and the tube imploded almost instantly. These things can't be that volitile, can they? Of course, it makes sense, seeming as though the inside of a picture tube is a total vacuum, so logically the outside forces would constantly be trying to crush it. I've seen modern tubes that had been broken apart before, and that glass is much thinker than I'd have thought.

Just some idle thoughts, I'm just curious how stable picture tubes are. I mostly collect computers, although I also have gotten heavily into televisions, hi-fi's and radios. Between all the computer terminals, television sets, radio tubes and the like, I'm beginning to wonder if it's such a good idea to collect this much of a vacuum together in one small house...

Yeah, I'm sure it is. Keep the balance of the earth and all... I'm going to go out and scour the shops for a color roundie again...
