Anecdote:


Ed from AAA told me that when Irv Wait visited Centuri he spotted a flaw in the automated press that was used to make Mini-Max BP motors. There were three cylinders, but only one cut-off sensor, so it was possible that only one of the three motors had had its fuel grain properly compressed. Centuri equipped each cylinder with a sensor (depth? amount of pressure?) so all of the motors received the right amount of compression.

No further details about how automated the process was otherwise.
