without it you just have more glass breaking and flying around. Perhaps I am all wrong on this but I thought that is how saftey glass was made (two layers of glass with a bonded memebrane that keeps the glass from shattering.

That is correct. But, when done the way we've been taking about, it is basically going back to the "picture window" type of safety glass, only curved to fit the screen instead of being further away. It's better than what's on my avatar Zenith, NO safety glass at all. I'm looking for the correct lens with the gasket. The 21FBP22 was an unbonded tube and uses the curved glass with an air gap like after a cataract surgery on a FJP but with the gasket rather than the double face tape. (preferably 3M automotive tape) I think it is safe.

Reason: I corrected my statement about the gasket, I had it reversed with the tape.
