I can no longer avoid making the various fiberglass ducts & whatnot for
    my cooling systems.  Can anyone give me some useful citations on how to
    work with fiberglass?  I don't have the first clue where to begin, so a
    beginners book with enough meat to get me through the (hopefully
simple)
    task of building a few KN ducts would be great.

    On a side note -- I need to make a custom oil pan.  Couldn't I make it
    out of fiberglass too?  The oil isn't all that hot, and it's not a
    pressurized system...  Just trying to kill 2 birds with one stone...

    There are some books on the subject sold by Aircraft Spruce.
    I'll check over my collection when I get home to day and
    see if I like one better than another.
    Go to any boat or yacht shop. They have most of the supplies.
    Get yourself a cheap kit and jump in.

What about the concept of a fiberglass oil pan?

I would not try it. Too risky. Too much to lose if it melts and leaks.

Composite Basics by Andrew C. Marshall 1994 looks pretty good.

Lancair uses the sandwich method. Get some painters drop cloth from your
local building supply and cut a piece of 1 mill plastic larger then what you
want to lay up. Put 2 or 3 BID layers of glass. Pour your epoxy mixture on
the glass, place another piece of 1 mill plastic over it and then us a
roller to work it into the glass. You can tell when it is fully soaked,
because it turns clear. If you have a form, simply lay the sandwich over the
form smooth it out and then remove the outer layer of 1 mill plastic. Do
your next lay-up and do the same thing. Do not forget to remove any plastic
from between the layers. It's simple and quite easy to do. To or three
layers of glass is all you can easily get the epoxy to soak through. 4 or 5
bid is enough strength for most applications, less if you are doing small
parts.
