I've never hand cranked my '47 Chevy but I've cranked my '46 Dodge many times. Shortly after buying the Dodge in 1974 I was headed to class and stopped for gas. After filling the tank I climbed in and stepped on the starter. It cranked and cranked until the battery ran down but didn't start. It was at this point I remembered I hadn't turned the ignition on. Luckily when I bought the truck the hand crank was under the seat. One pull and I was off and running.
