Jim,
Take advantage of the environment:
Gather walnuts locally (they will probably be Black Walnuts, better than the
thin, pale English ones) Pulverize shells with sledgehammer, etc. Put shell
material and wheels in a suitable container, seal the top.
Remove all outer clothing except for "long johns". Stand outside holding the
container with the wheels and walnut shells. After a suitable time, depending
on the temperature and how reactive you are to the "chills" you will have
clean wheels -- a Yankee version of the Vibratory Abrasive Finisher.
Keep your steam up!
Mr. Lunkenheimer
