Well I got the glass cut without breaking it, but as you can guess its a long way from fitting correctly. Nothing a little metal work won't fix. That's why you cut the glass first. LOL! Brian its ok to say I told you so. You live and learn from your mistakes. If you don't try you don't learn anything. This is why I wanted to fit the glass before I finished all the metal work, so I could adjust if needed.

Wow. Pictures! Pictures! Pictures! Congratulations. Anyone who cuts their fist curved windshield on the first try has something to brag about.

It was really easy with a siphon sandblaster cutting the outside first. You just go slow . I made about 3 passes then went down to the plastic. Flipped around and did the same thing on the inside. Then got the old beltsander and smoothed the edges. Took about 4 hours, but I did it myself and didn't have to pay someone else to do it. Not that I'm opposed to paying,but it does feel good to do it yourself.

The pattern I made showed how the lower corners needed to be cut to lean the glass back. You can see by yours, that is exactly what needs to happen.

When this happened I need to add material to the lower corners right at the base of the A pillar because as it leaned back that bottom corner pulled away from the A pillar. But it went pretty smooth up at the top I don't remember much mods other than a little at each upper corner. The bottom is were most of the work went.

I am blown away that you pulled off cutting that glass. What kind of sand blaster?

Brian, it's just a cheapo craftsman siphon type loaded with black beauty. I believe I will try to cut the bottom corners first before any metal work begins. I'm just concerned cutting there will cause the glass to shrink from side to side, becoming narrower and causing more problems if you know what I mean. On a side note ,I'm concidering purchasing a shrinking disc any info you have on these would help. Are there any tutorials on is useage.

Thanks Al

Yes, that is exactly what happens and that is why you will need to modify the hole! That is the beach with the glass, you can't change it's shape like metal! It is very unforgiving. I wish I took photos like I do now back when I did it!

I do remember having to narrow the hole a little, when it was all done it worked out pretty good, you could hardly tell. I do remember looking at other trucks after I did that one and seeing once you look up close that they had done the same thing.

shrinking disc

I saw one demo-ed at a car show several years ago. A guy watching ask if he could try it and was not sucessful so I kept my wallet in the pocket. A friend chopped his 49 merc and had one so I took another look. The principle is similar to using a torch. With a torch you heat a spot. it swells up, you use a hammer and dolly to flatten down the hump. The metal shrinks and pulls down the surrounding metal. A shrinking disc is the last step after you have used a hammer , dolly other tools to get the metal as close as possible. You need to have the paint removed. The spinning disc heats up the high spot, it tries to hump up more , you apply pressure to force the hump down then lightly raise the disc to allow the spinning disc to circulate air and cool it. There has been quite a bit of discussion on making and using a disc on the metal working sites such as metalmeet, metal shapers, allmetal and others. I used a stainless steel plumbing clean out cover on my 4 1/2 grinder, it worked but the larger ones sold for a large grinder will be faster.

I have to assume you posted this to the wrong thread, we are talking about glass here. The shrinking disc is an amazing tool, I don't know anything about the way you describe it's use. From what I was taught is you run the disc over the panel it hits only the high spots kinda like a "Heat block" and then you cool it with air just as you would shrinking with a torch or any other heat creating tool.

I have done little with mine, but what I have it worked out very well.

well i've got the glass fitted to the hole. It took cutting the glass a few more times. Like around the bottom corners and alittle at the top corners. Tim your tip with the gasket saved me from making some big mistakes. I was fitting to the wrong area of the hole. Now comes finishing the metal work. I have tacked the frame back together now fill in all the gaps, have the passenger side looking pretty good. will get pics soon.
