    That crank is a work of art. This should be another impressive engine.

    Very nice. What material did you make your model crankshaft from?

    Too bad about no pics, hope you document the rest of your journey for us because its a very admirable project.
    Can you describe some of the tooling you used - ex parting tool to rough? home cut HSS tools to finish? any lapping?

    Thanks Cogsy
    And the metal I used for the crank came from a shaft from the draw works on a water well drill rig I once owned. I roughed out the crank on the mill with rotary table and tailstock with a fixture on each end to index rod journals then ground journals to final dimension on the lathe with tool post grinder. As my father owned an automotive machine shop for 52 years I have reground hundreds of crankshafts so it made sense for me to do it this way. I’ll post pics of fixtures next time I go to shop. Thanks for your interest.

    Very nice work there. Will be following this one with interest. I worked in a Chrysler factory back when a hemi was the hot money.

    Yep a little more to do, at least I think I’m past the point where I might screw up and have to start over!
