Remove Lock Ring for the Pivot-Adjustment Screw
The slotted lock ring for the pivot-adjustment screw can
be difficult to remove unless the proper tool is used. Do
not attempt to remove the slotted lock ring and pivot-
adjustment screw unless you have access to such a tool,
since the slot in the lock ring will likely be damaged if
you use an improper tool, making removal of the lock
ring much more difficult
A suitable tool for this task can be easily made by filing
or grinding a relief notch for the pivot-adjustment screw
in the center of the blade of a large slotted screwdriver,
as shown in
Figure
11. Note that if you decide to make
such a tool, be sure that the tip of the screwdriver you
select has a blade width matching the outer diameter of
the slotted lock ring, and that the thickness of the blade
is such that it will seat fully into the slot of the slotted
lock ring.

Don't even think about using a pair of needle-nose pliers to loosen
the slotted lock ring. It will end badly if you do this. Don't ask me
how I know this.

Prevent the Revolving Turret from Spinning
Before attempting to loosen the slotted lock ring, the
revolving turret must first be locked in position relative
to the stationary base, to allow for sufficient torque to
be applied to the slotted lock ring to loosen and remove
it. To lock the revolving turret, first spin the revolving
turret until the bore in the stationary base aligns with
one of the four threaded objective bores in the
revolving turret. Next, insert a small screwdriver handle
of the appropriate size into the two bores (see
12). This will prevent the revolving turret from moving
relative to the stationary base when torque is applied to
loosen the slotted lock ring, without causing any
damage to the fragile brass threads in the revolving
turret.

Loosen and Remove the Slotted Lock Ring
Hold the turret assembly by grasping the knurled ring
on the outer perimeter of the revolving turret and use
the slotted screwdriver with the notched tip (see
11) to loosen the slotted lock ring securing the pivot-
adjustment screw to the stationary base (see
Figure
