(28) CHECKING SQUARENESS OF PIVOT AXIS AND DOP ARM AXIS. (Fig 13)
This is done with the “D” Dop.
Locate and lock the Dop in the Dop arm. Lower the head down to approximately 90
0
and adjust the Index Cheater
so that the straight edge of the dop sits flat on the Master Plate. Now move the Head up to an Angle reading of
around 45
0
. The straight edge of the Dop should sit flat on the Plate. To check if the Dop is sitting flat, depress the
Index Pawl while putting a little finger pressure on the top of the Dop. If the Index Wheel kicks then the Dop is not
sitting flat.
(29) INDEXING.
When indexing, depress the Pawl sufficiently to clear the teeth in the Wheel. Do not skid the Index Pin over the
Teeth. The Teeth relate directly to the Facet being cut. If when depressing the Pawl, the Cheater knob turns,
moving it from the Zero setting, it can be tensioned with the ferrule on the opposite end of the shaft.
(30) FREEWHEELING. (Fig 14)
To freewheel the Index Wheel for Preforming the Girdle, the Pawl is depressed and the Catch Knob turned to clip
over the end of the Pawl and free the Wheel.
