Yes, it was engaging. No idea why he chose brass for the solenoid formers,
though. I'd have used nylon or acetal myself. You can get the stuff in
round stock specially made for turning and it's dirt cheap.

It looks like a heavier than needed duty design.

He could have used cardboard tubes for that matter.

Maybe he was thinking about 'galling'. not that this assembly would
or even could ever get to a situation where any such thing would
happen.

OR perhaps he used different metals to get a feel for how his
machine tools worked with them, thereby making himself more atuned to
their use.

I noticed not a lot of cutting fluid and was waiting at one point
to see the brass get a hot hue on it (the drill through looked hot).

Did notice a bit of axial non-linearity. Might have been a non
flat mating of the flywheel though.
