John,
I'm not sure I understand what you mean by the
following:
"Offset grinding the crank to get the additional 1mm
of radius on the journal bearing center..."
The simplified(?) picture in my mind involves shaving
metal off of one side of the throw shafts (if that's
the right terminology, the shaft section that the con
rods connect to - I'm a technical geek, but not much
of a gear head) gradually tapering the grind to keep
the shaft round. This would shift the center of the
throw shaft out by half the distance of the maximum
thickness of metal removed. If that makes sense, and
is actually what you propose, then I'm amazed that it
can be done at all, let alone be regarded as a
relatively safe approach.
I don't see how any other metal shaving anywere on an
existing the crank shaft would do anything to change
the stroke. Though I am willing to be enlightened.
Greg
