is this something a person can do at home? or should it be done by a pro at the shop. thanks

Polishing is done with very smooth emery cloth.
The stuff in a roll.
Use very very fine emery and take the sharp edges off using a chunk of metal or a vice.

Put some oil on the journals, wrap the cloth around twice and
pull on either end.
You don't want to remove any metal. Just shine it up.

At a shop where the crank is being SPUN at the same time to prevent flat spots and ridges, and possible failure at an earlier age than necessary...

A friend of mine polishes them using a setup he made. A couple wooden V-blocks support the crank while a drill motor and belt spins it. The belt rides the flange for the rear oil seal. Uses strips of very fine emory to do the polishing.

How does he polish the rod journals?

He uses a double wrap of emory cloth. The variable speed drill turns slowly so it's easy to keep tension on the emory by hand.

I've used crocus cloth on cranks to polish the journals. It's VERY fine.Just oil it up double wrap the journal and go at it.
