> We had a VT14 at the RICM that had cataracts. We used dental picks to
> remove the silicone holding the metal mounting band to the CRT. We planned
> on using a hot wire to cut the PVA, but when we started picking at the
> edges of the PVA we found that very little PVA was adhered to both the CRT
> and the shield. Cleaning up the PVA was tedious, but not difficult.
> We were concerned about putting a CRT without the PVA in a public place in
> the museum. We had images of a young visitor breaking the CRT and glass
> flying everywhere.
> We bought some 0.093" thick Lexan at Home Depot, waited for my wife to go
> shopping, and put the Lexan on top of the glass shield in the oven. When
> the temperature hit 325F the Lexan conformed to the glass shield. We
> trimmed the Lexan to the same size as the glass shield, and use silicone to
> hold everything together. This is probably a lot safer than the original
> PVA and won't degrade.
> There are pictures and a description of what we did here:
I love that you clearly pointed out the most important step in this repair
waited for my wife to go shopping
