(11) VERTICAL SLIDE. (Fig 8)
This moves up and down the Post to position the Stone being faceted in relation to the Lap Plate. A Rack and
Pinion is used to do this, being operated by a Large Knob. In the center of this Knob is a smaller Knob for locking
the Slide once positioned.
If the Head has a tendency to freewheel down when the Lock is released, adjust the small tensioning grub screws
at the back of the Slide. Do not over tighten these screws. This will cause unnecessary wear on the vertical column
(Fig 9).

(12) PIVOT PLATE.
This Plate carries the Pivot Bearing and is secured to the Vertical Slide with four clamp screws and one “jack-
screw”. These screws are used to square the Pivot Axis with the Post and
SHOULD NOT BE TAMPERED WITH.
Special equipment is required to make this adjustment. If you ignored the above caution and now have the
machine out of alignment, don’t panic. Just call the factory.
(13) THE HEAD.
On the front of the Head are the two Knobs that raise and lower the Head and lock it in position. On the backside of
the Pivot Axis is another Knob. This knob is used to set the desired cut angle.
