Lube the ways, what the table slides on
Lube the gibs !! yes really ! the angles edges which define the tables limits.
Get out our dial indicators and place so they indicate the squareness of the table to a stable reference
Grab both ends of the table and try to twist it ! Do the indicators move more than 0.001" gibs too loose!
Move the table across its whole range repeating this test and getting the gibs set so the prevent more than barely indicatable movement but still allow free movement.
If you had been using hand motions all year, you would have developed a feel for the stiffness of the table movements. you can set the gibs so they add just barely noticible amounts of drag to the movements. But only if you have developed the feel of the table movements.
