Here is the video for the flywheel above.

Another example of me just blindly stumbling through the process, and getting just lucky enough to get a good flywheel casting.
Many of the other parts in this mold where thinner, and they were hard like tool steel, and a power hacksaw had no effect on them, other than to remove all the teeth from the blade.

Luckily the flywheel was thick enough that it did not have any hard spots in it.
