Re: [bolger] V belt transmission
- I knew a fellow who used an electric clutch to stop one side of a small
differential out of a 1941 Crosly Automobile. When the clutch was locked
up the output shaft turned one direction and when it was released it
turned the other direction. Worked pretty good. The same guy put a
straight eight cylinder buick engine in a 40 ft work boat. The engine
had a hydromatic transmition on it and the boat went down the river
changing gears as speed required. Sounds nuts but he made a living
catching crabs with it..
