So I finally made it in today and was able to deck the haas table sub-plate. HOWEVER,
the slab is approx 34" and the hass only has 30" of X axis movement. So while I decked everything I could it should be noted that those extra 2" on each end are high spots that would affect anyone trying to do a workpiece larger than 30" in that it might bow in the center. For our vise that is plenty of room.
I should add that the two high spots were already there from previous deckings, just now it is more.
