  • Windshield Glass Old vs New

    I have had a IPhone for a while and recently started buying these 99 cent to $4.99 applications for it. Last night while playing I discovered that original Studebaker winshield glass is way different than today's glass. There is one "app" that is a GPS that can be hand held or used as a Heads Up display by laying the phone on the dash pad and it displays info just like a HUD. On both my SUV and Ellen's car the HUD displays perfectly. On the Hawk you get two images, they are spaced exactly apart as the thickness of the glass in the windshield, about 1/8th or less of an inch. Not only do you get 2 images, the spacing offset is equal to the angle between the inner layer and outer layer of the glass.

    I wish I could capture with a camera, last night it did not work. maybe if I try again I can get it to display.

    Maybe the exterior glass surface is showing up because its covered with minute scratches.

      I think it is because the older safety glass is made with some type of Mylar sandwiched between two pieces of glass. The newer "safety" glass (I think) is "tempered" to shatter in a way as to eliminate the need for the plastic sandwich of the older safety glass.

        Yes the older glass is two pieces with mylar between them. I made a mistake in buying a NOS original windshield, should have bought a new one. The NOS is much softer and gets road marks very easily.

        I think that the mylar might be making the image double. But it is still fun

          New windshields are also two layers of non-tempered glass, except in some european windshield glass, which is tempered; and will shatter.

            My glass guy tells me the old glass is thicker than the new glass. The new gaskets are made for the new glass and don't fit the old glass very well.

            If this is true, perhaps the thicker glass causes the two images.

                I am only downloading subway and bus maps of London and Paris, plus anything that has to do with flying. Found one that works in "airplane mode" that you place on your tray table in a plane and it reads out all the flight data, pitch, roll, yaw, artifical horizon and airspeed, vertical speed and altitude. Just discovered it is for small planes as the air speed indicator red lines at 250 mph. I am still trying to figure out how you can take credit cards using it and also print. I read somewhere the other day that by mid summer there will be a real time GPS Turn by Turn app.

                I just spent about 30 min in a dark garage trying to find a way of getting rid of the double image and how to secure the thing to the dash pad. I think it is quite funny to have a HUD in a 53 year old car.

                            H eads U p D isplay. Comes from the military, it projects your intrumentation on to your windshield. It also can be used in fleight helmets. Some car makers like Volvo, Lexus and MB and others are using partil HUD(s) to allow drivers to keep their eyes on the road rather than constantly scanning the dashboard. I think Cadillac was the first US car company to have about three years ago. Theirs was more infared to show humas and animals at night.

                              Try waxing the outside of the windshield and see what happens.
