Is there anyone with a plasma cutter and spare windshield??
someone knows if there is any technic to cut or saw windshields in our workshops with simple tools?
if it is polycarbonate use bandsaw/ jigsaw/ scroll saw then file / wet n dry then buff or polish edges- just make sure main surface doesn't get scratched by tools
I meant regular laminated glass windshields.
draw the shape you require, then using a carbide glass cutter, carefully score the line on both sides of the screen.
crack around the line you've scored and now you need to run methylated spirits into the cut and light it. it'll soften the middle laminate
enough to get some movement and cut it.
never done it myself, but i've seen it done

i remember seeing it done long while ago, glass cutter to score both pains then methylated spirits or lighter fluid into the crack and set light to it so the inter layer can be melted without damaging the glass edges. must be a alternative method now.

The method is very simple (as above, scribe and melt) but if it isn't perfectly flat getting it done is an entirely different ball game. Even
professional places I spoke to said they'd want "at least a couple of screens to try" and would offer zero guarantees.
I've heard elsewhere that a diamond bit in an angle grinder can work wonders, but knowing glass I'd like to see exactly how long before you
get cracks appearing - I think you'd want to firstly cut it to size, then spend a good amount of time polishing the edge of the glass to minimize
the chance of cracking.
The methylated spirit burning bit is a bit "old hat" now.
I use a hot air gun to heat the interlayer and then slice it with a single edge razor blade.
Takes a bit of practice, but works very well.
BTW I'm an ATA Master technician in Automotive Glazing.

What screen are you wanting to cut?
In reality any laminated screen can be cut down further, but some will be much more difficult than others due to the curves etc. It may take a few
"practice runs" to get it right.
Put it this way,I've chopped the black obscuration band down into 1inch squares for some research work we were doing a couple of years ago. It
took a long time but I did it eventually.
It's the latest Gen Celica I've been looking at. Not that heavily curved, but curved enough that I'm not keen on tackling it!
Somewhere I read that you can cut anything with a plasma cutter provided you have some conductive material to start the arc........

Would a water jet cutting system do it?
