Started the fabrication of the upper plenum. I am using the bottom side of the top cowl to form the mold for the plenum top. Sanded down the top cowl with 150 and 400 grit sandpaper. Then I applied a paste wax for a release agent. So far I have laid two layers of heavy fiberglass to mold the shape of the bottom of the top cowl. Once it cures I will pick up a corner and see if it is stiff enough to be used for a mold.
