Mark,

In your experience with the machine, did you also have problems with the
primary and micro bevels not being parallel, or simply the fact that your
blades were being ground out of square?

After reading your comments, I'm inclined to think that my problem may be
due to the different rates of abrasive wear between the coarse disks and the
9 micron disk used to apply the micro bevel. If the relative rate of
abrasive wear at the disk circumference was slightly greater on the coarse
disks than on the 9 micron disk, the effect would be exactly as I've
observed. As I think about it, the problem gets worse as the abrasives
wear. This would be consistent with your observations. The only problem is
that it doesn't explain why the micro bevel seems to always be greater on
the left side of the blade, no matter which side of the platter I run it on.
I'm going to recheck that tomorrow; my observations may have been in error.
