I have chopped the top on an old Chrysler and instead of filling in the curve rear glass (three piece back window) ends I was wondering if there is a way od cutting the curve glass. This is a 3 piece glass window. The center part is flat but the corners are curve and wrap around. Thanks. If you have any suggestions please E-mail me at, joseph.peter.carter.us.army.mil

It can't be cut it is tempered. All curved glass outside of the windshield is tempered (the windshield being laminated).

I have heard of magical beings who cut it with laser and sand blasting, never saw it and don't personally know anyone who has ever done it or knows someone who has.
As far as I am concerned, it is a fantasy.

I have tried to sandblast it, it blew up in my face.

I think you will have to resort to plexiglass. It has a bad rap but I made my corner windows for my 48 Chevy truck and they held up for twenty years or so with only minor scratches.

It can be cut with waterblasting. The reason it blows up is Too much pressure!.. I used to do blast (frost) images on truck rear windows. Masked Blue ovals, Chevy Bowties, etc. The secret is LOW pressure (35 psi.) and indirect stream.

Bob, have you actually cut tempered glass for a chopped top? Or are you going with theory? If it can be done I want to know.

I googled up these guys real quick.

You should first make a cardboard patern of the new window opening leaving enough room for a windows seal/gasket to go in. Then transfer this to a piece of aluminium. Curve the piece of aluminum to fit the opening perfectly. If you can use the old seal to try it out.
You'll need this to layout the lines for cutting your old glass down or sending off the patern to have new glass made if the old can't be cut down to fit right.
The angles and curves all change when you chop a top. Thats why so many people use a flat glass car to chop instead of a curved glass car.

A good place to try getting you glass cut localy is a head stone or marker cutter. They have all the sandblasting equipment and proper cutting medium along with the rubber stencils you'll need to mask off the glass. They also know who has a water jet and might be willing to try cutting it that way.
Just remember they will never guarantee it will come out ok. Its not their normal job.
