Hi
Attached is part of the factory drawing for a 1925 Steam Wagon crankshaft. I want to make a new reproduction crankshaft.
The crankshaft is made in two parts. It has to be 2 parts because eccentric cams to drive the valve gear are fitted on the shaft between the crank webs. Very occasionally the crankshaft will need to be disassembled for maintenance/rebuild.
The drawing shows the end crank and web attached to the shaft with a key (circled in red). The drawing does not define the fit between the web and the shaft. Most likely a press or shrink fit.
My question: Is there a better way to connect the two parts of the crankshaft?? Perhaps a tapered fit clamped in place with a screw and washer down the centre of the shaft. Is there a better alternative to the key?
