If the blade is removed and replaced about 180, the low/high reverses.

If the blades are swapped, the low/high is still about the same on the

The last two statements are contradictory -- if the high/low position
interchanges when the blade is rotated 180 degrees on the spindle, that
would indicate a bent blade as any tilt or bend in the shaft would be
the same and the location of the low spot moved w/ the blade.

My error. Got a bit confused. the high stays the same.
