If you are trying to cut your own glass and this is your first time use some kind of oil on your glass cutter. Do not cut glass with a dry glass cutter you might waste your glass. I dip my glass cutter in motor oil but any kind works. Also it only takes one cut or pass with your cutter from one end to the other to make a cut. Dont let your straight edge move, make your cut ,then break.
Most people think when their car door window is not going up or down its off track. Usually whats happening is the regulator inside the door attached to the window is bad. Put the keys in the ignition and try to roll the window up and down. Now while doing this listen very closely for a crunching sound. If you hear this crunching sound your regulator is bad and the cables are frayed or broken. Call me 352-445-1036.
If you have some glass laying around and you are wondering if you can use it to fix something you need to know this. Tempered glass is glass you cant cut down. If it is tempered it will have a mark on one corner etched in the glass. Glaziers call this a bug and it lets you know do not even try to cut down. Also never set it down without putting wood or something under it because the edges of tempered glass are the most delicate and it will explode or break in thousands of little pieces.
How can someone throw stones at a glass house when they already live in one.
Today I did a windshield on the passenger side of a semi truck that was a split windshield. A turkey flew up out of the ditch and took out the glass. If it had happened on the driver side it would have been a different story. He was going 60 mph. There was no window left.
