cut down windshield
I had a rear window out of a 91 chevy truck so I used a carbide cutoff wheel in my makita angle grinder. moving slowly with lite pressure and cutting both sides of the glass, I had it cut all the way through except the last 2 inches. it went off like a shotgun.if I would have used water to keep it cool I mite of made it. if you use sand blasting,duck tape it good and keep the pressure down to 40 lbs.
