Clear Vision Panels

Palmer mentions these as being available from an automotive firm in Canada.
Apparently the firm is no longer in existence. Anyone know a source?

Clear vision as in for wave flying? The simplest goal is merely an insulating
airspace...although decent vision would also be nice for the lower-level
operations. :-)

Any clear semi-rigid (yet flexible) plastic attached inside the canopy with
(say) double-sided foam tape would likely serve. Tape removal would likely be
the larger issue in the long run.

Years ago I seem to remember using lexan bonded on with some black
'silicone-like' caulking compound. Undoubtedly, better attachment options have
been developed.

I've always used clear mylar, cut as needed and Scotch binders tape,
which is easily removed. My needs were temporary at wave camps rather
than for a full winter season.

I use Lexan panels on the inside of the canopy. Once they are made, the
panels can be installed or removed in just a few minutes, and used again
for many seasons. I've been using my panels for about 10 years now. You
can download my article on them from here (140K pdf).

Here in frosty Canada (you know the place.....igloos, Eskimos, polar
bears!) we used to apply frost shields onto the inside of the
passenger windows or rear windows on vehicles that did not have great
interior heat. Of late I have not seen them on the store shelves but
a manufacturer shows up close to my home city of Winnipeg. Check
out : http://tarpsandfilters.com/frost_shields.php
Perhaps they can help. Meanwhile I have to go throw another log on
the fire.......minus 30C this AM, and time to put a jacket on when I
go out!

You Canadians are great folks but you exaggerate the temperature. My
friends in Vancouver complain bitterly when temps approach "0" by which
they mean a mere 32.

Well, this is off-topic but.........
When testing plastics for UV transmission and comparing acrylic, lexan
(polycarbonate), and the fancy expensive plastics sold to prevent UV
damage to art and objects the acrylic varies quite a bit from as good
as the others to poor, the Lexan is very good. Most newer gliders
have canopies that reject UV enough to make it a non-issue, but if you
are concerned about UV this might be a factor in your choice of
materials.

For winter flying, the UV is so low because of the sun angle, I don't
think it should be a concern. Summer flying - different story.

The advantage of polycarbonate is it's easier to work with than acrylic,
and far less likely to crack when bent for installation or in use.
Acrylic is better optically, and it's what I use for the front, flat
panel. If I could find acrylic thinner than the 0.060" stuff available
locally, I'd probably make the big panel out of it, too.

Although you are correct in saying that those in Vancouver complain at
0C, as do those in Seattle, you ought to check the weather records of
Winnipeg (Winterpeg as we Canadians call it) and Anchorage.

http://pafc.arh.noaa.gov/misc.php?page=climlist -38 F Anchorage
http://weather.uk.msn.com/monthly_averages.aspx?&wealocations=wc%3aCAXX0547&q=Winnipeg%2c+CAN&setunit=F
-54F Winnipeg

Having said that, under -10F you put on all the clothes you have so
you have to take a run at doorways, and it's still cold, so the
difference between -38 and -54 isn't that big a deal. ;-) You could
die either way.

My mother and her twin sister were born in Moosejaw, Saskatchewan, but
went to school in Camper, Manitoba, (173km NNW of Winnipeg). In the
early 1930's they were walking the three miles to the one room school
from the farm (been there, it's the real distance). It was extremely
cold. Their younger cousin wanted to lay down and go to sleep. They
knew that meant he was freezing to death, so they kept him walking and
dragged him along. They weren't allowed to return home later that day
as the claimed temperature was -65F. That's not inconsistent with
record lows reported in Manitoba around 1933/34. Sometimes they
skated to school on the frozen irrigation ditches.
