table movement
adjustment
the sliding table features an adjustment bar with
bolts that control how easily the sliding table
moves across the base (see
figure 139). these
adjustment bolts are factory set. they can only be
accessed by removing the end covers from both
ends of the sliding table base and sliding the thin
plate out of the way.

adjustment
Bolt
if the adjustment bolts do require adjustments,
turning them counterclockwise increases and
clockwise decreases pressure against the steel
rails. increasing pressure against the rails reduces
table movement slop, which increases accuracy,
but makes it harder to slide the table. decreasing
pressure against the rails makes it easier to slide
the table, but increases table movement slop,
which reduces accuracy.
adjusting this part of the sliding table correctly is
a matter of trial-and-error by making adjustments,
moving the sliding table, then making additional
adjustments and repeating the process until the
sliding table moves as desired. ideally, the table
will move easily but without any slop.
