However a .016 variation is more than 1/64 of an inch.
This amount would make it virtually impossible to make anything like a tight
edge miter of any length (say, for a speaker cabinet) with the blade tilted.


Once again, not necessarily. You might get a surface that is ever so
slightly more rough than perfection. Probably take a profilometer to
measure it. You might get a touch of burn, although I doubt it. But
the wood travels past the whole blade. Doesn't mean that any part of
your cut is .016" off to any other part of the same board.

However, as you might know, a plane is established by three points
only and your table and cabinet are four. You may improve by shimming
one corner, if the bulk of the "problem" is either parrallel of the
plane of the bosses to the top of the table or plane of the top plate
on the cabinet. It is all trial and error. Or if bevel cuts are a
way of life for you, you might cheat your 90 setting the other way a
little.

And you might call Powermatic to see if they have any tricks. They
will probably tell you it is within specs. but may give you some
ideas.

However, if it were mine and I were within .016" with a dead on 90,
I'd lock it down and cut wood.
