The Ford Barn - View Single Post - Who lightens flywheels? Looking for a shop

At a place I worked many moons ago, we had a dedicated lathe for lightening flywheels. We did a lot of them. We always balanced them afterward. We never had any problems with any of them, EXCEPT ONE in a 32 roadster. I just happened to be the passenger and the driver was going to show me how he could full power shift (button shift) with his new light flywheel. He missed the one two shift, the engine went over 7K free winding and the flywheel exploded. It was a toss-up whether the car or the people got the worst of it.
They quit lightening flywheels. Too many possible harsh side effects.
