Jointer Bed & Table Flatness

You worry too much. On ancient 24" jointers used by a crew of 120 men
continuously for 2 ten-hour shifts a day, we are able to produce model
and pattern bases that suck down strongly upon a steel or granite plate,
and edgewise are square to a 4 foot master square.

One of the most important things in a jointer is the closeness of one table
being parallel to the other. If that isn't dead on, you will never be able
to joint a board and have it come out straight. Never.
