This is the step where the design becomes a reality. Your design should take
into account the materials and tools required to produce your car from them.
Be sure and use proper safety procedures and equipment when working on your car
and remember that it must be able to stand up to the rigors of racing.
Thorough prototyping of components helps the final vehicle construction go
smoothly. Parts built for experimentation may also be used in the final car
design and construction.
Building usually takes more time than you think, especially if the students are
not familiear with the materials. The teacher and mentor should ensure that
there is adequate time and supervision for the build sessions.
