Norm, yes, sounds like the same style setup would do both jobs.

The key will be some way to safely load the output shaft without building huge heat. Just now I am visualizing a large disc brake rotor with large caliper. Maybe 2500 series truck parts.

A simple single master cylinder with a long handle to apply load.

What I do not have is a mental picture of is how to adapt a brake rotor to the output shaft with an easily removed, stable, no runout setup.

Maybe someone will have a simple idea.
