Flywheels achieving linear motion

[KenWittlief]

my father use to work at a factory that had big presses. A belt spun a large flywheel (very large - hundreds of pounds) and the energy of the flywheel was transferred to the press (to stamp a piece of metal to an extact length).

Im afraid I dont know the mechanics of how it worked, but since it was a standard factory machine you should be able to look it up and learn the basics behind its operation.
