Okay, going back through what I typed I think it could be
misinterpreted.

I do have the fence parallel to the blade and whether it's square to
the front edge of the table doesn't matter...What I'm expecting is for
the fence to point up, away from the ground, at 90 degrees to the
table. That is, if the fence extended up further, I'm expecting it's
sides to be plumb to the table (of course I'm not expecting high
precision).
