More work done today. I really can't be working on this every day!

I'm going to try to reuse the original bearings.

Crudely cutting them out:






One Bearing Free.





Second bearing free!




Two Free Bearings. I'll clean them up some other day.




Tools used:

$9.99 Harbor Freight Angle Grinder.

I know you’re well on your way down this path, but I saw this at work and thought of this thread. This thing, with a custom die, a pneumatic cylinder of about 8 inch stroke, and a manual air valve would cut out your parts faster than you could toggle the lever on the valve. Maybe rig the lever up to a reciprocal saw blade that also drives a set of feed rollers, and go full Rube Goldberg. Ofc, you'd have to source that stuff, but something tells me if anyone could, it’d be you.

That's a great idea. There's only one small problem.

I don't have one of those.

You would if you built one! Side plate and pin design, maybe? That type would be cheaper to buy steel for.

A friend of mine recently closed his shop. He's got three of those flywheel presses he'd sell. One of them is pretty large. He made parts for a well-known large electrical company (his grandfather started the business in the '30s) until they pulled his contract and moved production to....China. Saves 'em a dollar on a part he charged $1.87 a unit for making.
