A job on the lathe! Lightening a Flathead Flywheel.
 

In today's video I try my hand at lightening a flathead Ford flywheel. I didn't want to go too mad at it, but did take a few pounds off it. I also had a stab at balancing it using a method I have been developing. I think it came out ok, I hope you do too.

I would be very careful about using a lightened cast flywheel without having a steel scatter shield to contain the parts if or when it comes apart. Safety first.

Yes, I was riding in a 32 roadster (no scatter shield) and the driver was going to show me how fast he could button shift. He missed the shift. According to the tatletale the engine freewound to 7400 and the flywheel exploded. We both got shrapnel in the legs. It almost cut the car in half.

Cast iron flywheels and clutches are not allowed in race engines any more.

Dam Pete that must have been one heck of a day you have scars to prove it.

We had one blow at the track, no body got hurt but a piece of the wheel was 4" into the track/ The 59 wheel I have in the roadster street engine is an early one with the lip cut off so I could install the 9 1/2 clutch, but it's been balanced
