The cowl had to be modified to allow it to clear the exhaust. The shapes are laid out using welding rods as splines, covering the shape with sheetrock seam tape next, then filled with lightweight joint compound. After sanding to shape. The entire area is covered with plastic tape as a mold release and the fiberglass is applied. Before removing the glass, reference holes are drilled, then the glass removed. Next its trimmed to shape and glued back in place with Gorilla Glue using clecos as clamps. Sand and fill...
Since discovering spline method of making complex shapes, I am not going back to glass over foam or clay anytime soon! I am still messing around with the process and will write it up after I figure it out completely. Its kind of a mix of cutting foam cores for model airplane wings and finishing your basement ; )
Below are the first test shapes.
