Re: Worth it to lighten flywheel
I have a friend that machines parts for the aerospace industry that balanced mine. I cut the back of the flywheel down on a lathe,the front with a surface grinder and he balanced it. Balancing can not be done by just any machine shop. Most shops that cut cranks can balance cranks and flywheels. My flywheel was balanced on a single-plane vertical dynamic balancer at 2500 RPMs. But that is not what a automotive machine shop would use. They probably would use an arbor shaft horizontal plane strobe balancer of some kind. Precision Balancing Company in Indianapolis, IN has a good reputation. (317) 639-2712
