Thanks Archer, I haven't had a chance to see the victim yet as my son hasn't found time to bring it over.
I intend to remove the crystal as part of the service, but one thing I'd like to avoid is removing the bezel assembly if I can avoid it. Would you consider it safe to heat the tube enough to break down the adhesive without damaging the bezel, or would you always remove the bezel?
I realize the question depends on how drastic my heating technique is. I'm thinking of a large soldering iron in contact with the end of the tube (along with a little solder to help the heat flow), perhaps with a foil shield between the iron and the bezel, and keeping them as far apart as possible. I've got a 75 watt soldering iron that will heat up almost any tinwork.
