This is interesting. I was told from a composite expert that one could
fashion the shape of a complex manifold using sections of hotwired blue foam
initially appearing as a blue foam pipe. The pipe is cut into setions and
glued together and sanded to shape. The whole thing is coated with silcone
seal and layed up with glass. disolve the foam with solvent and pull out
the silicone with pliers. It is supposed to leave a smooth surface. I Have
never done this but it could work.

Here is a picture of Bernie's intake. It is made from fiberglass wrapped
around bicycle inter tubes that were filled with sand to hold the twisted
shape. Bernie said that the only problem he had was getting the tube out of
the fiberglass when it cured. Maybe he could chime in here and give the
full story on there creation.

Has any one made an intake from composite? I thought Ed did but I am not
sure on the limitations. Does the fuel/air mix pose a threat to the
integrity of a composite intake? Backfire? Combustible? For those of us that
built their airframes from composite it might be easier than welding. Just
a thought.
