Once upon a time I ordered a casting set, advertised as "can be built with drill press". My drill press was not big enough so I was unable to complete several of the operations alluded to in the provided blueprint. Many years later I met Herb and eventually the fly wheels were drafted for the above blue engine.

Will take video when I get another engine on bench.
