Cut the window down today. It's 7 inches narrower. I left all the channel, weather strip, glass in during the cutting, and putting it back together. Tomorrow the window, walnut paneling, EZ lock for powered wheel chair, inside, and outside ramps get installed. Coming along well. Bob Dunahugh

You cannot cut tempered glass. If you try it will shatter. I assume he just let it overlap the other pane 7" more.

Sully,

Not sure the finished width -- but you could mix the front sliding section of a large window with the fixed section from a rear (smaller window). If I remember the large are 60 inch, the smaller 36 inch....

Jim,

Thank you for the information --
like others I am eager to know what approach Bob took. I think his original plan was to increase the overlap (as Emery mentioned).

Couldn't you cut any glass with a sand blaster, even a windshield?

I was thinking cut one side/layer of glass with the sandblaster, then the other side with the sandblaster, then cut the plastic with a knife or something.
Probably want to practice a "proof of concept" with a scrap windshield from a wrecking yard.
Seems like it would be less "hit or miss" than conventional windshield cutting, which is not always successful.

The original post was about side glass which is tempered and cannot be cut by any method known to man including waterjet. It simply becomes a million little pieces.

Within the thread it was proposed that the tempered glass could be cut with a sandblaster. By that logic, if a sandblaster wouldn't break the tempered glass, I thought it might increase the probability of success when cutting windshields and other glass/plastic/glass laminates.
Chock it up to thread drift.

Jim Miller...


Jim, back in the 'day' all glass was laminated safety glass and therefore cuttable by a variety of methods. I'm not sure when tempered glass came about. I think my 57 Imperial has it but am confident that early 50's Chebbies did not because I recall seeing bubbles around the edges of the glass in the laminate on my first car, a 51 Chevy.

Only rear windows used tempered glass as far back as I can remember.How many rear windows have you seen broken that didn't break into a Zillion pieces?

Help me install new windshields at Dothan, and you can have the old foggy ones to cut up and test your method. LOL

Jim --
Have you ever done this or are you just repeating hearsay? I have sold a lot of glass, annealed, tempered and laminated in the years that I owned a window/door distributorship. We had sent a sheet of tempered glass back to the manufacturer as they said they could anneal it, cut it and then retemper it. But I had never heard of cutting it with a sandblaster.

So, I did an Internet search and found several sites that said it was a myth. Several people reported trying it and shattering the glass. I did not find a simple post that said anyone successfully did it. One poster said that he went through a 100 pound bag of sand and only went about 1 mm into the surface and his glass was 3.5 mm thick. He said he took a break and when he came back he found the glass panel shattered.

I doubt that Bob will want to try it with the extremely high risk of breaking it.

Windshields are laminated glass, not tempered.

Quick Window Sizes, based on the outside frames, not the interior hole size needed to mount the windows.

Door/Kitchen 24 7/8 inches
Small Rear Side 29 3/4 inches
Large 23 foot side 37 1/8 inches
Large 26 foot side 59 5/8 inches

I have OEM window screens for the early windows if someone wants them hauled to Dothan. Also the glass. No latches.
Also, the large 23' side window from the Gene and Jim show.

Have to admire Bob's determination and drive. I would still be measuring stuff. Hope to see his final results at a GMC rally.

If you even put a small chip in the edge of laminated windshield glass it will likely develop into a crack. When we install windshields at the shop we check them very carefully prior to install. If it has even the smallest chip it is refused. But modern windshields are structural and held tight to the body with window adhesive sealant with a strength somewhere over 1200 psi. A laminated glass which sits in a gasket may not be as sensitive. The back glass that came in my 77 royale had been cut to fit out of laminated glass. The corners were ragged but it did not crack even when I manhandled it out thinking it was tempered.
Some high end vehicles have laminated back and side door glass ( Mercedes 500 series) as an option. Some also have double pane laminated glass in the side of the doors.
