What happens here
After the fuel system is primed, the 1964 Watson Roadster is started using its external starter. The car's unique construction is detailed, highlighting its frame partially built by Lockheed using World War II aircraft fasteners and heat-treatment processes to normalize the chromoly steel, preventing brittleness from welding. Its brakes, referred to as "lobster brakes" due to their appearance, were repurposed Goodyear aircraft brakes. The spindles were sourced from a one-ton International Harvester truck, and the transmission is a modified Model A transmission. The car runs on a blend of methanol and gasoline (a 50/50 mix with a quart of acetone).
Goal: Start the primed engine and understand the car's unique material origins and engineering.
