gibs are wedge-shaped pieces of metal that
fill the gap between the sliding surfaces of the
machine. by adjusting the position of the gib in
its gap, you can remove any play that might exist
between the adjacent components. the gibs are
pre-adjusted at the factory but due to storage,
break-in, and usage, may require adjustment. if
movement seems too tight at first, make sure that
all the rust preventative that was shipped on the
machine is removed from the ways. lubricate the
ways with oil, and work the table back-and-forth
several times until the movement is easier.
To adjust the table gibs:
1. disConneCt mill/drill From poWer!
2. loosen the table travel locks (figure 56).

To adjust the headstock gibs:
1. disConneCt mill/drill From poWer!
2. remove the two screws that secure the top
end of the way cover, pull it down to expose
the lower gib screw, then loosen the vertical
travel locks (
figure 57).
3. loosen or tighten the front and rear gib
screws ( figure 56) in an alternating manner
to adjust the cross travel gib.
the table should slide smoothly in the cross
direction with no play or looseness. do not
overtighten the gibs or premature slide and
gib wear will occur.
4. lubricate the cross way and gib.
5. repeat the process for the longitudinal way
gib using the gib adjustment screws on the
left and right sides of the table base.
3. loosen or tighten the upper and lower gib
screws ( figure 57) in an alternating manner
to adjust the headstock gib.
the headstock should slide smoothly with no
play or looseness. do not overtighten the gibs
or premature slide and gib wear will occur.
4. lubricate the headstock way and gib.
5. re-install the way cover.
