So the windscreen is abbreviated and the wheels are flush with the fairing rather than being totally enclosed. The underside can be fully faired with a separate piece of coroplast. The fairing is made on a mold, which is a gel-coated and waxed fibreglass shape. The plywood cross sections are cut to define the final shape, and are placed in locations where width and clearance are critical. It's worth spending time to get the shape exactly right, because a lot of fairings can be made from the mold.
Entry is via the top.
The windscreen is cut from a Zzip Designs polycarbonate experimenter's bubble. There are bulges at the front to allow room for the toes at the top of the pedal arc, and the bulge behind the head is a natural continuation of the curve of the windscreen. The top is left open for ventilation, and also to limit the height of the vehicle. This is the skeleton of the mold. It is made from plywood sections like an egg crate.
