The final racer constructed would depend on the materials, tools and skills of the builder. The design at right was included to illustrate that it is possible to build a streamlined racer without having to form curved surfaces.
Curved surfaces can be very difficult to shape in wood.
Some people have access to different materials and skills than others. Kids of all ages can enjoy building a racer. The 3 steps are shown below to give an idea of the complexity and amount of time, skill and work that can go into a racer. The wire screen is stapled to the wood to provide a base to hold the fibre glass. The fibre glass has been molded over the wire screen and an entirely new body design has taken shape.
