  • Page 1 12 Brass Dops , 3mm. to 8mm. in Flat Cone and V Form Angle Dop. Two Setting Dops. Transfer Block. Available From.

  • Page 2 Just a quick note before you get started. We wish you the best with your new machine. The owner’s manual attached is NOT a thesaurus for how to cut stones. Others do a much better job at that than we. Although we have a rather generous drain tube setup, I must caution you NOT to use too much water drip.
  • Page 3 Patriot Calibration The Patriot was designed for easy calibration. Upon power-up, loosen the large angle set knob at the back of the head. Depress the dop holder to its most downward position. At this point, the pivot block will come in contact with a calibration set screw.

  • Page 5: Setting Up The Machine

    A little care here can save pain later. (3) ELECTRICS. One of the features of the Patriot is the digital readout. The digital display and electronics are contained in the control box, along with the motor speed controller. STOP.

  • Page 6: Water Bottle

    The Power Circuit and the Electronic Circuit is shown in (Figs.3 & 4) A “zero” set/ cut to zero set lever switch is located on the right side of the control box. Warning. When changing Direction of Rotation, switch to the “Off” position and allow the machine to come to a stop before making the change.
  • Page 7 Fig 5 (9) SWING ARM AND POST. (Fig 6) The Swing Arm that carries the Post is mounted below the Base plate on the right side. The Arm is tensioned with an elastic stop nut. This stop nut is factory set. Fig 6 (10) VERTICAL ADJUSTMENT SLEEVE.
  • Page 8 (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.
  • Page 9 Loosen this knob, raise or lower the dop arm to the desired cut angle, tighten the knob. At the approximate center of the pivot plate is a fine adjust knob used to set the cut angle. (14) PIVOT BLOCK (Fig 9) The Pivot block pivots around the Pivot Axis and carries the Dop Arm (Quill) assembly.
  • Page 10 (19) ANGLE DOP (45 Deg Dop) (Fig 10) The angle dop is inserted in the Dop Arm, located and locked as above. The dop holding the Gemstone is inserted in this Dop and locked with the Grub Screw. This arrangement is used to cut the table on the stone. Fig 10 (20) CHECKING ANGLE DOP SETTING The 45...
  • Page 11 (22) LAP PLATES. It is essential that Lap Plates run true. They should not be bowed or of uneven thickness. They can be checked with a straight edge and micrometer. Copper and Tin Laps can be machined to run true. They need to be held against an accurately machined Master Plate in a lathe to do this.
  • Page 12 Fig 13 (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 and adjust the Index Cheater so that the straight edge of the dop sits flat on the Master Plate.
  • Page 13 Fig 14 (31) INDEX MICRO ADJUSTMENT (CHEATER) (Fig.15) This provides adjustment for aligning the Facets when cutting, if necessary. The cheater also allows the operator to completely polish the Facets. Turning the Knob towards the operator rotates the Dop counter-clockwise, turning the Knob away from the operator rotates the Dop counter clockwise.

  • Page 14: Electric Motor

    (32) ELECTRIC MOTOR One Brush wears more than the other, especially during slow speed operation. Periodically they need to be reversed. This will prolong the life of the brushes. (33) CARE OF THE MACHINE. Always keep the machine clean. It is just as important to keep the hands clean also. Avoid placing the hands on the Vertical Adjustment Sleeve.
