Default Help rebuilding a pedal-powered grindwheel

I have an old pedal-powered sharpening stone something like the ones
pictured in the links below.

The metal parts are so rusted the frame no longer stands up by itself.
I am going to rebuild it if I can just get the stone rounded again.
The center square hub hole is in good condition, but the outer rim is not
concentric with the hub.
One side is about 1 inch greater radius than the other and the wheel is way
out of balance.

How do I get the stone back into usable roundness and balance without
breaking it?

You use a dressing wheel with the star carbide spokes.
It will take the wheel down while you pedal.
you'll need help... (pedal power).
Those manual powered ones are great. Lots of speed control .
The only problem is steadying the piece while you pump away.
