At least one person here has used a thin wire to cut
the bonding, then
removed the front piece of glass, cleaned it up, and rebonded it. It
sounds like a dangerous project to me, not only because the CRT could
implode while you're cutting it, but also if you don't get the bonding
strong enough when you put it back together and the CRT then
subsequnectly implodes, the results would be very unpleasant.
That does beg the question of under what conditions a CRT implodes. Do
age-related implosions happen (or implosions for other reasons other
than mechanical shock)? I've never heard of a CRT imploding, except for
when physical damage has occured to it - but presumably it does happen.
In other words what are the risks - or is it a case of over-engineering
in the first place to make sure (to a reasonable extent) that there are
no problems out in user-land?
Also curious as to the extent of the outward blast / debris field (that
sounds horribly technical but I can't think of a better phrase!) when a
CRT does implode. I'd *assume* glass just extends outward a foot or two,
but happy to be corrected there! (of course an explosion would be a
rather different matter)
Actually, is the faceplate actually there for dsamage limitation reasons
- or in fact there to help prevent implosion in the first place from
mechanical shock? I imagine that coupled with the sealant layer it
provides a reasonable damper if the CRT is dropped with face-down.
Any people on the list involved (past or present)with CRT manufacture
who can provide more information?
