| Subject: | Lexan for windshields |
A word of caution with Lexan windshields. We have a Rans S-6 at our field
with the Lexan windshield.The owver spilled a very small amount of fuel on
the tightly curved portions next to the wing root. The windshield IMMEDIATELY
crazed ! It appeared to be shattered to the eye. I later talked with another
S-6 owner and he had 2 windshields do that and he had to replace both of
them. He now uses a cover over the Lexzan when refuelling.
I think the Lexan was not properly heat formed in these areas and was
under constent stress so when the gas hit it....POW ! Lexan is very easy to cut
and form compared to plexi so I think it was just one flat piece.

I used a spin saw.
First I would put tape over the glass where I was going to cut. If your
glass still has the protective plastic on it leave it there. Then I used a
board clamped to the bench at both ends just as a guide for the spin saw.
Take it easy with the spin saw and don't rush.
When drilling holes I always deburred to prevent cracking through the holes.
I personally tried using a hot welding wire to actually burn holes so the
edges would heal and increase the strength.. It worked for me but others
have said it didn't work for them.

I tried using my bandsaw on a scrap piece but it came out looking like crap,
all chipped up and crooked. Then I used a 4" thin metal cutoff wheel on my
angle grinder and followed the line I drew. It came out nearly perfect, no
chipped edges and almost perfectly straight. The 4" wheel wants to go
straight and it was remarkably easy. Just take it slow and don't try to cut
through all at once. I made several passes, making the cut a little deeper
each time until I was through. If you try to cut all the way through in one
fell swoop, you will end up melting the plastic.

One other point Scott after using your cutoff wheel on plastic it may be a
good idea to reserve that particular wheel for cutting plastics only. The
rule of thumb I was told with any grinding medium was not to use it on any
metal that doesn't spark. For instance grinding aluminium causes shards of
aluminium to imbed itself in the wheel where it can heat up causing the
wheel to explode.

Do you mean the tool that fits in your drill and spins like a drill bit?

Yes but I use mine in the Dremel (11,000rpm ?) the spinning action of the
saw blade is self cleaning and makes a very smooth cut without heating up
the plastic. Without the wood as a guide a straight cut is very difficult
though.

The Dremel is certainly a handy tool. I use it all the time. I have used the composite
cut off wheel to do plastics, but usually use it on metals. I now use
the Dremel blade that looks like a toothed round saw. Like something you might
see on a table saw. I have used this blade on several plastic projects and like
it better since the other composite cut off blade can sometimes melt the plastic
and leave a terrible edge. The round tooth saw blade does not melt the plastic
and leaves a nice smooth cut and with the variable speed of the Dremel
making a nice edge with this is easy.
