Due to WSC regulations, our new car must have 4 wheels and additional head space. These new design challenges were meet and optimized by Andrew Liotta our lead engineer who designed the chassis. Dillon McConnon, our system lead made sure the chassis integrated well with the other subsystems such as the aero shell and electrical boxes.

With the design complete and tolerances adjusted, we have now begun the building process. Using 4130 steel tubes, cut and coped to fit at the correct angles the chassis is welded together. This is a challenging and precise endeavor as it is important to have a minimal gap between adjoining rods in order to make a strong weld.

Once set up (with jigs to hold things in place) the tubes are welded together. In fabrication of the chassis, the preparation takes longer than the actual welding time. Below is a time lapse of one evening’s effort of welding done by Thomas Villalon.
