Steam Engine Restoration Part 7 - Refinishing the Crankshaft, Crosshead, Connecting Rod, and Piston

Before beginning the fine mechanical repair work, I finished sandblasting, cleaning, and repainting the major mechanical components that I had decided to reuse. The crank bearings will need to be rebabbitted, the crankpin has to be reground, and various missing or damaged parts must be remanufactured from scratch.

The crankshaft as removed from the engine. The shafts cleaned up nicely, but the crank pin is toast.
