Building Your Solar Car
1. Deburr the axles by brushing the ends against sandpaper. This will
make it easier to push the axles into the wheels.
2. Using a drill or drill press with a 9/64" bit, drill two holes in the plastic
body as shown in Figure 1. Hole A should be drilled 1-3/4" from the
back of the body (under the motor slot) and 1/2" from the top of
the body (opposite of the grooved side). Drill through all four plastic
surfaces, keeping the drill bit parallel to the top and perpendicular to
the side.
3. Hole B should be drilled the same way, with the center of the hole
1-3/4" from the front of the body and 1/2" from the top of the body
(Figure 1).
