Athough the wheel on my 511a grinder is 'centered' as far as getting equal length cutters R & L, It does not appear to be 'centered' for the depth gauges.
I am getting different heights for the right and left depth gauges, due to the different parts of the wheel curvature that touches each.
So I am now grinding all of the right depth gauges, then readjusting the wheel height, and grinding all of the left depth gauges.
The chain remains facing the same direction due to the positioning dog.
(But now I really want a 511ax with the sliding vise!).
