Adjusting Gibs
Tools Needed: Qty
6mm Hex Wrench ...............................................1
The Model G0645 has a dovetail gib located on
the side of the headstock (
Figure 32 ).
The gib controls the accuracy of the sliding parts
and keeps them stable during operation. The goal
of adjusting the gib is to remove unnecessary
play when the slides are moved, without tighten-
ing them so much that they bind. The gib can be
tightened or loosened by using the adjustment
screws.
To adjust the gibs:
1.
Loosen the cap screws and move the head-
stock up or down slowly while turning the
adjustment screws.
2.
Tighten the cap screws when you obtain a
snug fit between the column and gib with a
minimal amount of side-to-side movement.

3. Replace the gas spring on the ball studs so
the ram end points down.
Tools Needed: Qty
Flat Head Screwdriver ........................................1
When working correctly, the gas spring shown in
Figure 33
keeps the headstock under pressure
so it does not drop when the operating handle is
released. If you ever notice that the gas spring
stops working correctly, then promptly replace it.
To replace the gas spring:
1. Raise the headstock as far as it will go and
set the depth stop to keep the head from fall-
ing.
2. Pull the gas spring off of the ball studs, as
shown in
Figure 33
.
Tip:
Position the flat part of the screwdriver
close to the ball stud on the gas spring as
shown in
Figure 34
, to prevent snapping the
ball stud off.
