 you wrote: Thanks Dave. To make the radiator ducts, I was actually thinking of
doing this. I figure I can wrap the core in plastic, tape the mouth of a kitchen
garbage bad around the inlet side of the core, open a hole in the bottom of the
bag, then fill it with foam. My thought is that this will leave me with a nice ball
of foam to be shaped. Can anyone think of a better approach?
Thanks, Rusty (I sure won't use expanding foam from the spray cans again)


        You can actually just tape some cardboard that is as tall as the max distance to
the opening around the edges of the cores after you have wrapped them with plastic,
pour in the foam material and let it expand. Your duct is always going to be smaller
than the core as you move away from the core. the pour foam is MUCH easier to sand
and shape than blue or pink or white styrofoam.
