glass people

Was doing some looking around online and found people who have had success cutting tempered glass with diamond blades, rediculous amounts of lubricant/coolant, not turning the cutting blade a too high a RPM and a hell of a lot of luck. I also found articles that mention using a "special laser" and with some more research found they are talking specifically about CO2 lasers on a 3D arm so that the line can be cut at 90 degrees to the medium with a coolant stream.  They said this cuts down on refraction within the medium and allows the cut to be made successfully. I also found the method below to turn your tempered glass into regular glass so you can just score it and cut it how you wish: http://www.ehow.com/how_4678952_cut-tempered-glass.html Tempered glass cannot be cut, except with special laser cutters used by professionals. The only way to cut tempered glass is to first anneal the glass, which involves heating the glass to approximately 900 degrees, and then allowing the glass to cool slowly over approximately 8 hours. Step 1 Clean your tempered glass thoroughly and dry completely. Step 2 Place your tempered glass into a craft oven and set the temperature to 900 degrees Fahrenheit. Once the glass has reached this temperature, turn the oven off and allow the oven and the glass to cool for at least 8 hours before removing glass from oven. This process is known as annealing, and it removes stress from the glass. The glass is no longer tempered. Step 3 Lay the sheet of annealed glass on a clean, flat surface. Step 4 Place your T-square or other straight edge along your cut line. Step 5 Dip your glass cutter into kerosene for a smoother cut and then grab your cutter as you would a pencil. Starting at the edge of the glass, run your cutter along the straight edge, applying just moderate pressure. Make your scratch with one smooth motion, applying the same moderate pressure along the entire line. Do not run your cutter over the glass a second time. Step 6 Place your 1/4-inch dowel under the glass directly under the scratch. Put on your eye protection, and then apply a sharp downward pressure to the glass on either side of the dowel. The glass should snap cleanly along the dowel and scratch. Step 7 Rub your whetstone along the freshly cut edge of the glass as if you are lightly sanding the sharp edges. Round the edges slightly. This makes the glass stronger as well as safer to handle.Hope some of this helps, 

I like the idea of turning tempered glass into regular glass. Thats a good idea. I wonder if you can then turn it back into tempered after the cut or is it gonna be to brittle. It also seems like there using flat glass which would be more stable on a table.  I like the phrase, "and a hell of a lot of luck".  I dont see why with alot of patience, you couldnt do the sand blasting trick on tempered. 

If you dont have to take more than a 1/4 off you can use a belt sander!!! I have taken a 1/4 off of 1/8 thick tempered before with no problems but i have never tried that much on 1/4 thick.

I was using a sander and a water hose to keep it cool. I let it get too hot and it shattered.For that method too work it would take me a week probably to cut it. I need roughly 2in cut off the glass. The oven idea sounds cool but where in the hell do I find an oven that gets that hot that I would be able too use as an indivual?

Our Dakota was a regualr cab and from the way choppedn22d did the chop, there is maybe a 1/4" hole that doesnt seal in the door glass. Of course that's without the window trim installed but the door channel inside is huge! and can be cut to let the window travel farther ino the door. And to top it off, that same hole looks like it will be covered by the window channel/trim. The only thing to worry about is the rear window to be made. but that's flat.  The side glass ext cab windows can still be used, just hit him up to see what he did. rather genius if you ask me...
