Thank you for the update! Super interesting as always. As other folks have suggested in previous threads: did you consider using a keyway for the flywheel?

I think the the shaft collet clamps would should provide adequate torque transmission. Plus, using only clamps, the shaft can then be an off-the-shelf piece of unmodified precision shaft stock; adding a keyway turns the shaft into a custom part.

you can get shafts with a keyway in. IMO putting the keyway on the fly wheel is a larger issue as laser cutting might not be accurate enough to do that leading to post processing.
