I've had alot of people ask me about this so here you go.Unfortunately I was in a hurry and didn't take any pics. so I'll try to stumble through an explaination.I used a sand blaster to cut my wind shield down. From what I have found the key is the inlet air pressure needs to be about 40-45 psi and to work quickly across your cut line so you don't build up to much heat but don't rush the process.
I used 2 x 4's to make a jig for the glass to sit in . I then used a single layer of duct tape to cover the glass and three layers next to the cut line.The sandblaster can't cut through the tape but the extra layers give you some insurance. I made the first cut straight across the glass then I used a razor blade to remove the laminate in the middle .(which even after fifty years still smelt like ass and feet.)I then flipped the glass over and used a glass cutter to score it and broke the piece off with the glass tool that looks like a pair of pliers.(you can get these tools at home depot) Then I repeated the steps on the round corners. After I finished cutting them I used and air grinder to sand the edges smooth first 40 grit then 80 grit and finally 180 grit.The whole process took about three hours because I was cautious I was leaving for the round up in two days and didn't have another glass to use! :grin
One more thing it's easier to make the car fit the glass.Cutting metal is alot easier and you can weld it back together if you screw up. http://www.jalopyjournal.com/ubbthreads/images/graemlins/grin.gif http://www.jalopyjournal.com/ubbthreads/images/graemlins/grin.gif
