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.
The (plastic) faceplate is *not* an implosion protection, it is a contrast
and anti-glare plate. All (TV) picture tubes since around 1968 have an
implosion protection that is integral to the tube and not simply glued on
top of it.
Second, a CRT won't just implode on its own (that's a fairy tale). The
front screen really needs a very big shock before it cracks. The most
fragile part of a CRT is the section from the conus to the neck of the
tube. And if the neck should break the rest won't implode, the parts are
just too solid. There were several companies in the old days who removed
the neck of a used CRT and replaced it with one with a new gun system.
