Eccentricity of rotor journal is .591 inches or 15 mm.
Main journal diameter is 1.6918 to 1.6923 inches.
Rotor journal is 2.9122 to 2.9128 inches.

OK But I still need the radius to the rotor tip - Vance

As near as I can measure it from the rotor bearing surface
to the tip is 70.8 mm.

Some time back someone submitted a simple rotor shape
equation written as a point rotating about a point which
was rotating about the e-shaft center. In a following submission
that simple equation was corrected (I think) to correct for the
radius of the apex seal. The corrected equation may have come
from a Madza paper. I wish I could provide more detail but I
dumped a big hunk of my inbox during a senior moment recently.
Maybe my wife will buy me Paul's CD for Christmas !!
