Very simple material to work with. The first 3 pics are of the finished piece (it will keep water from spilling over the transom of my raceboat. I used .20 gauge Plexiglas.

Becuase of the many angles I had to make a mold or a form to clamp the plexiglass into as I heated the bend points one at a time.

first I made a cardboard pattern, and then cut the plexiglass to the pattern

Then I finished the edges, first with a belt sander, then with an orbital sander, and then hand sanded with some
1000 grit so the edges becomes translucent. After this, I marked the bends on the glass with a marking pen, using the cardboard pattern, and simply laid the bend point over the edge of a board and heated it with a heat gun on high. You must move the gun rapidly back and forth, and on a small piece like this, the glass will fold over by itself in about 3-4 minutes. When the glass falls over it is very pliable for about 2 minutes, and I just clamped it into the mold and let it cool. If you are making a simple windshield with 90 degree bends, no mold is needed, just heat it in the same manner, and it will bend over, all by itself, don`t try forcing it. If you start with a level table to bend it It will fall to 90 degrees. After it falls over, lay a wet cloth over it so seal in the bend. It is very simple to do, and work with. Don`t overheat as tiny bubbles will form in the glass.
