I am pretty darn sure it is 1/8".

Hmmm. Interesting answer - probably what the questioner wanted, but I was thinking 'What's half the stroke? Ah yes, 2"'

From the research in building the six 1914 replicas, the radius between the bearing surface and the side of the crank is specified as 0.125”.

It has an 1/8th, .125 inch Radius. No bigger, or smaller. Rods, and mains should be cut that Diameter, also, or you will have a mating problem.

A 2" Radius, should be closest to a 15" Diameter crank.

Would the Model A & B crankshaft also be 1/8"?
