In 1959, when I was a poor apprentice, I restored an Ariel MF.
One of the flywheels had a crack from the big end out to the edge. I turned some mms off the diameter of the flywheel, and made a steel rim from flat iron, which I turned to size and shrank onto the flywheel.
Then the crack was under control.

Most flywheels crack between the two holes, as the tapered pins force them apart if overtightened. Very difficult to repair satisfactorily.. Nev
