Customs When cutting glass for a chopped Merc

Hey Ya'll
When cutting gl*** for a chopped Merc windshield, how would you measure the gl*** in relation to the opening and the rubber gasket. just say the opening is 20' x 12" (not Actual size) how much would you subtract for the gasket?

 

The best way to do it is to have the actual gasket you are going to use them make templates out of 1/4 Masonite that fits in the windshield hole exactly like the gl*** would.

Once you have a left and right template, have your gl*** shop match them exactly. Make sure they don't trace around your pattern with a sharpie then cut it because your gl*** will be about an 1/8 too large all the way around.

-Abone.

 

Are you talking flat gl*** or curved gl***?

 

When we do gl*** for the chopped cars we've built we use the actual rubber gasket and the proper door channels and cut our patterns out of 1/4 inch tempered Masonite. This material allows us to make sure the windshields will fit and the door gl*** will slide properly and the side stationary gl*** fits the quarter windows frames. I use Street Rod Gl*** in Riverside CA. Also always temper the side gl***.

 

Thanks Guys
That sounds really straight forward

 

It helps if you have the stock gl*** to trace a pattern on cardboard or Masonite . With caardboard or real heavy card stock you can trace the pattern, cut it across the middle and overlap it on the windshield opening and tape it to get your starting shape to trace on the masonite.

 

If you do the pattern without gaskets, you subtract 1/4" from the pattern to allow for the gasket.

 

Would you measure 1/4 subtraction from each side?

 

A well know gl*** man told me and a friend to use the 56 Ford f100 gasket material. I think if you cut it in two and measure the center section, you will find that it measures .125. So my understanding is .250 total. If you are using a different gasket or are using a glue in gl***, you would need different calculations.
