Description
This is the proposed design for a crankshaft design using a simple return arm.
Features
- Crank arms are balanced by equal weight of metal on both sides of the centerline of the shaft.
- Crank pin is balanced by taking an equal length of metal, splitting it into two, and welding the pieces on the opposite side of the crank arm.
- Pillow blocks with internal bearings
With careful welding, this crankshaft should come close to being balanced, though the piston rod may upset the overall balance. Balance can be further adjusted by removing or adding metal to the offset weights.

Fabrication Notes
Welds are shown in blue in the diagram above. Initial prototype of the crankshaft should be welded rather than complicating the design with an assembly that can be taken apart. Later, a more modular design might be necessary to accommodate multiple steam engine cylinders.
