I have a '51 GMC 5 window that has been chopped. The corner windows that I have are solid gl***. I am told that the solid gl*** windows are made of tempered gl***. All of the corner windows that I have seen have been made of solid gl***. So far the only way I know of to tell if the gl*** is tempered is to try to cut it. If it explodes then it was tempered. So I am looking for a set of laminated safety gl*** corner windows. Several folks claim to have seen the mythical laminated corner windows but so far I have had no luck. If anyone has a lead on where to get a set of laminated corner windows I would sure like to hear from them. As long as I am asking is there a way to check to see if gl*** is tempered without destroying the gl***?
You in the springs? Black cab? I have never seen those windows in laminated. Check around some of the 50's chev websites and see if the new ones are laminated? Good luck.
You CAN tell by looking at the edge of the gl***. Laminated has two layers of gl*** and the plastic film in the middle. Also the etching should tell you if laminated or tempered. I did not think that tempered was used until the side gl***, door windows, started to be curved. When was that? mid 60's?
tempered was used a long time ago...the original flat back gl*** in my 39 chevy was tempered. Curved tempered back gl*** came out about that time.
somebody ought to make that gl*** with 3" chopped out. if you chop your cab more or less you can adjust the window opening to fit..
The guy that cut my windshield, said you can take the temper out of the gl***, with heat, cut it and retemper it. We were going to to do it to my 1 piece door gl***. It's tempered.
YO man I have 3 sets of them I will look at for ya. Worse case try to cut it IF IT BLOWS UP PM ME AND I'll send ya another set.
I think the corner windows and most other pre-late 60's curved gl*** is annealed. It not quite the same thing as tempering, but is done to add strength. According to wikipedia, annealed gl*** can be trimed or shaped, but I guess I'm not going to try it with my gl***.
I got my new corner gl*** from the Gl*** House in San Dimas, CA, and did it by phone. They do custom cut gl***. http://www.thegl***house1.com/
I have always wondered if Dodge extended van gl*** could be used. tempered gl*** can be cut down by sandblasting.
I have a kiln that the corner gl*** will fit into but I am trying to avoid the 2+ days of heating and cooling. And not knowing if it will work after all that makes me a bit nervous. Not to mention what all that kiln time is going to do to my electric bill.
I looked at the gl*** and near the bottom there is a marking that says "solid safety plate" so I guess that it is tempered. I suppose that I will try to cut it, if it breaks I am no worse off than I am now.
You could always do it the lobuck method,slice the upper edge of the opening and slide the gl*** in then install your rubber and seal the top with the black stuff.I did this on the winshields of a '49 chevy coupe i chopped back in the day,worked out ok
I have a friend who made his own chopped corner gl*** for a pu like yours. He took 1/4" plexigl*** cut to slightly larger, layed on top of the original gl*** on a cookie pan, and put it in the oven. Not sure of the temp or time. It was 15 years ago. When the plexigl*** had settled into the shape of the gl*** he took it out and let it cool. Then cut it to shape with a saber saw. Worked great. I know this is an old post...was drawn to it by your signature...must be a body man...illigitimus noncarborundum - don't let the *******s wear you down. Funny...I haven't heard that line in years.
lay a pecil on the gl***, if you see 2 reflections, it's safety plate laminated, if not, it's solid gl***. Never seen any AD corner gl*** that wasn't solid.
I think someone makes repops of the gl*** corner windows in plexigl***, that could be cut. Try Patrick's in AZ
