I assume that CRT's (rectangle color 23v 25A 25X) seem to come in two flavors of implosion protection.

Bonded face or Tension band no face.

I see the common fix to bonding that is broken down is to remove the lens, and the bonding agent and re attach the lens around the perimeter, effectively removing the lamination which I assume is where the implosion protection comes from.

I have seen rebuilt CRT's with ONLY the band (and not the formed steel hardware that is often seen on this era CRT). I assume these rebuilts started as bonded and part of the rebuild was to use a band (no other steel frame). I do not know this as a fact but I think scotty used to rebuild rectangle and remove the lens and bonding agent and install only the steel band on his rebuilds.

I have seen rebuilts that also had a bonded face (the channel masters in the foam boxes), which I presume had been rebuilt with guns AND rebonded (but are failing again).

This is why I am hoping someone that actually did this for a leaving (rebuild crt's) like Scotty may address. I am in no hurry to do it with out hearing from someone that has done this professionally.

I would be all for rebonding if I knew how this was done, not sure of the bonding agent or if special equipment is used to install.

Of course could just do like many others and just remove the lens and reattach with no bonding many have done with no reports of spontaneous implosion.
