    Anyone know a place to get windshields cut in Missouri ? I can get side windows cut just no luck on windshield.
    I tried cutting gl*** myself. Old gl*** didn't cut well. I'm not going to try new gl***.

    It's a 54 chevy car with curved gl***. I've tried local and a few of their ideas , no luck finding anyone yet. Someone has to have had it done.
     
  3. I've heard of guys that have masked their windshield with duct tape except for the cut line, and then used a sandblaster to cut the curved gl***. I've never done it myself, and I can appreciate your reluctance to go at the new gl***. But, anybody that says they'll do it for you won't guarantee success either.

  4. Think I would get my hands on a junk windshield,and teach myself. Find some sort of thin cut off wheel with diamonds,or carbide in it.,and use a high speed grinder. Wear a real good respirator face mask since that fine dust is bad news.May be run water over the cut to keep dust down.Cut it down several times for practice.When you feel like you mastered it do your good gl***.Since its laminated theres plastic in the middle so ask a gl*** shop how to seal the edges after the cut.

    I can share some experience with you, I had a local gl*** shop agree to cut my gl*** but there was absolutely no guarantees, if it broke it's not their fault and I agreed, two windshields broke before the third was cut to perfection.

    Cutting curved gl*** is risky at best, I watch him cut all there and he did nothing different when removing the excess gl*** after the initial cut, but twice a crack ran across the windshield. HRP

    When i chop a car i do the gl*** too, so does the guy that chopped the top recommend anybody to cut your gl***? I'm sure he knows somebody since he does the fab work. Danny is correct, there is a certain amount of luck involved. I've probably cut 20 that came out perfect with one piece of gl***, and i can think of 3 right off that took me more than 1 to get it cut. Cut straight lines, creep up on your finished dimension 1" at a time, and use your belt sander to finish any tight curves.

    Ideally a water jet would do it nice but I have read here on the HAMB that sand blasting is pretty reliable.

    Thanks for the advice. I will give it a try. I have 2 old windshields but I want to install a new one.

    This has to be the best video that I have seen for gl*** cutting.

    If your planning on chopping the car in your profile it might be much easier to buy a new hardtop/ convertible windshield. They are 2" lower than your sedan.

    If you sandblast or use a cut off wheel the heat WILL brake the gl***, don’t ask me how I know. Water jet goods like a good idea.
