When you have finally got your moulded windshield trimmed and fitting
correctly...take the time to take a large piece of paper and make yourself a
pattern. Takes a bit of work tucking and taping to get a tight fit. Trim the
pattern for an exact fit on your windshield and then fold it up lightly and
put it somewhere safe. It will come in really handy for the day your
windshield cracks. If it's too late and your forgot, you can always pull a
pattern off the windshield when it is removed by first taping the crackes up
tight, or pieces back in place.

Having a pattern on hand today made trimming of a new windshield, that fit
perfectly within the original retainers, less than a 20 minute job!!

Having the pattern made up ahead of time would let you get your new
windshield cut and ready before pulling the cracked one out of your airplane
for a quick turn around.

Also the ONLY way to trim the acrylic windshield effortlessly is to use a
Dremel and a fiber cut wheel that's about 1 inch or so in diameter.
Absolutely effortless and I have never cracked a windshield (and have done
at least a dozen now). It cuts and polishes the edge pretty much at the same
time. Once cut I run the wheel down each edge to chamfer lightly with the
wheel turning away from the windshield. Then a quick sanding with 150 grit
around the perimeter and a wet sand with 220 and it's good to install.

Cheers,
Wayne
