Figure 9 – Screwdriver modified to remove slotted lock ring
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, in order to allow for sufficient
torque to be applied to the slotted lock ring to loosen
and remove it. To lock the position of the revolving
turret, first spin the revolving turret until the bore in the
stationary base aligns with one of the five threaded
objective bores in the revolving turret. While holding
the turret such that these two bores remain aligned,
insert a small screwdriver handle of the appropriate size
into the two bores (see
revolving turret from moving relative to the stationary
base when torque is applied to loosen the slotted lock
ring.
The handle of the screwdriver should safely
prevent the turret from spinning, without causing any
damage to the fragile brass threads in the revolving
turret.

Figure 11 – Loosen the slotted lock ring
Once the slotted lock ring has been loosened, remove
the screwdriver handle from the bores in the revolving
turret and the stationary base (which is locking the
revolving turret to the stationary base) to get it out of
the way. Unscrew and remove the slotted lock ring
from the pivot-adjustment screw (see
Figure 12 – Remove the slotted lock ring
Remove the Pivot-Adjustment Screw
With the slotted lock ring removed, use a suitable
slotted screwdriver to unscrew and remove the pivot-
adjustment screw from the center bore of the
stationary base (see
