Once the board reaches the second fence, I start pushing the board

But you shouldn't push so hard that you raise the back surface of the
boark off the table...all you need is to contact the fence to keep a
smooth cut. If the shaft is perpendicular to the table as it should be,
all is golden. It shouldn't be too hard to shim the fence to correct
it, either.
