Indy 500 Legends Testing Day: Inside Access! Classic Race Winning Cars Back On Track

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.

Tools and materials

  • External Drive Shaft — Connecting the starter to the engine
  • External Starter Motor — Starting the engine after priming
  • Acetone — Additive to the racing fuel blend
  • Gasoline — Component of the racing fuel blend
  • Methanol — Component of the racing fuel blend

What they say

Hide

to um Lockheed the guy would weld them up put them in the oven normalize them and then bring them back the next day you explain what that means normalizing a chassis is when you when you weld 4130 parts of it get brittle so you're trying to make everything back to being normalized to where not one part of the car is brittle not one part part of the car is too hard so you're trying to take the parts that did not see heat from the welding to the point where they also saw the same heat so it's equal again exactly okay that makes sense and then this body was built in um California in Los Angeles at Cal medals the spindles are built by International Harvester really the brakes the brakes these are hellbrand brakes Lobster brakes cuz they look like a lobster back but they came from goodye from airplanes and then Ted went and Reid them but these spindles were off of a a a one ton International Harvester truck that's cool shaft over here to start it it's a 66 Pline that's also what the shaft is for for between the transmission and the um rear end and it had these couplings so there's a coupling in the back at the transmission at the rear end and then there's a cou a coupling that slides at the transmission is that like a PTO shaft from a tractor or something yeah yeah this transmission is a Model A transmission came out of a model a car or truck and then when hbr he had he had these cast these the Bell House and the transmission are both cast magnesium and then he also did the um the steering gear and the steering gear it has worm gears in it you can take them and and turn them around and change the gears and then it can be a left steer car right steer cars were all asphalt cars left steer cars were all dirt cars why was that the way that the geometry work for them I I honestly don't know um this car the motor has been turned around see the header comes out the left side on this car yeah so whatever side the the header is the steering is opposite if you look at the kosma car the steering is on the left side and and exhaust is out of the right side that was they used back before the um the Roadster showed up they would use these cars at at dirt tracks and at uh Indianapolis Trenton Milwaukee bill vukovich when he showed up with the fuel injection special was the first car to ever race with this conventional style shock on it and was the first car to ever win with this style shot holes drilled for like some arrow for his hands okay for your hands yeah so your hands…
