You are correct. Little protection is given by taping the safety glass to the crt.

That said, as hobbyists, we do not have the materials or equipment to do this kind of rework.

Even at Hawkeye, a fairly large crt rebuilder, the safety glass was fastened in place with a bead of silicone sealant and carton sealing tape around the circumference. If Hawkeye didn't have the resources to bond the safety glass, then I think it unreasonable to think we can do it.
