Gunner...Is the outside edge of your table on your mill higher than the
inside part of the table where the T-slots are? I assume that the table
should be completely flat from edge to edge and end to end. I guess it
is likely that the the inside of the table has "sunk" over the years
because of things being clamped to it. It looks to be from .002-.005
low in places. My plan was to completely check the table end to end and
then draw file it back into shape. Any suggestions? Thanks, Steve

Use a big flycutter and take a skin cut over the whole thing. You need
a big one so you can reach the edges. Make sure you tram it in so it
cuts a flat surface. The only problem is if your ways are worn. If
they are worn the top of the table will have a crown in the middle and
cutting it will only make matters worse. You can check the ways with a
straight edge and a dial indicator mounted on the table and the straight
edge on the knee.
