I think the water is an integral part of it. Before I started the water soaking the bonding material was quite hard and very difficult to penetrate. After soaking in the water it was very pliable and rubbery feeling. It would be extremely difficult to get the wooden pry bars in there unless the stuff was soft enough, and I think that's where the water comes into play. The day I put it out into the sunlight, it was still pretty brisk outside. I felt the screen and it was just warm to the touch, so I don't think the heat played a major role in the release. Bob

update the wire I used on the green cat to slice thru the goo was a .02" not
.007 that I thought. I have some CD scratch remover I plan to try on one of the smaller scratches. Also picked up some foam 3/16 wide by 1/4 thick stick on window seal. I plan to use that to space off the lens from the CRT. |

Given the chemical composition of the PVA, I don’t see why 30% acetone in water would not work. The key is distilled water. Who knows what is coming out of the garden hose? I have well water that is hard as a rock (because it is a rock) 51 grains of hardness. It turns brown overnight with all the iron in it. Mix it with my soft water and the sodium will tie up the acetone and nothing will happen. I did get a laugh out of many of the responses. Don’t drink the bong water!

I take it you live in the "love canal" area. You should check if the water is flamable. you never know you could save a mint on gas. LOL.

Wonder if a little dish detergent in the water would help. That would relieve the surface tension and make the water penetrate better. Also, if the water were warmer. I'm envisioning a pan elevated on some bricks making an "oven" with a light bulb underneath to keep the water warm.

I'm waiting until we start to get into our hot summer months!

just a note, if you decide to use pressure to finish up the job (as opposed to waiting another month for the lens to just fall off), I would consider what others have said, the glass will crack if too much is applied. You dont need to see any movement when inserting spacers (chop sticks in my case) just snug them in to a void (which will be easy to make as you can pick out around the perimeter the softened pva). I gently tapped them into the voil until it sounded "solid" then walk away for a few min, observe the fingers starting to form, go around the perimeter again and tap to make sure still snug, walk away, repeat. It starts slow but the last 25% of the contact area goes very quickly, with a satisifing "pop" as it finishes up.
In my case it was a very sunny day, maybe 85, the glass was quite hot, I should have used my IR gun to check it but a ruff estimate would be 120f |
