Tyngsborough, MA
I wanted to brush my idea through this wonderful wealth of knowledge. This is the BG for my recently acquired HS. As you can see the lower 1/3 of the art has lifted completely but its mostly in tact. I have read of the triple thick and cellophane trick but that does not scream "good" results to me. Here is my idea, and the 1 part I am unsure about is the best adhesive to use.
1. flood glass/art in some sort of optically clear adhesive- triple thick, cyanoacrylate*, other*
2. Place non stick sheet on top of art- I am actually using a Teflon sheet.
3. Place flat backing board on top of that-1/2 MDF
4. Place whole assembly into to "space saver" vacuum bag and add excess adhesive rags along perimeter.
5. Suck air out of bag.
6. Enjoy beer and relish at the results- TBD.
My theory is you will get nice even pressure with a vacuum bag, it SHOULD suck all air bubbles out of it as well. A typical shop vac can actually achieve a pretty deep vacuum.
The issues I foresee:
It would be best to remove the lift off lip as well as the rest of the edge material, i am afraid this is the only thing hold that art in place ATM. Also, the best way to get the adhesive onto the glass without disturbing the artwork. Lastly the best glue to use. I am thinking the triple thick but am not sure on its viscosity, also getting into a pourable state will be annoying since it comes in spray can version only. Cyano might work but might cause off gassing white burns all over the place.* Also cyano is moisture curing glue so it probably will not cure in a vacuum environment.
