Rich,
The crankpins would be conventional in every way, all turned diameters
would be axial, and yes the taper is essentially only a means of securing
the pin. But the taper will allow the crankpin and wheel to behave very
much like a collet where when the drawbar is loosened the pin (and the
return crank) can be adjusted to very fine limits. This would not be
necessary if my return cranks were bored for a round crankpin stub end but
I intend for them to be square so a means of locating them exactly, or of
fine adjustment, is needed.

Harry
