POLISHING WITH DIAMOND PASTE
The GP6-6 Wheel Cab Maker comes with three syringes (5 grams each) of diamond paste in abra-
sive grit sizes: 8,000, 14,000 and 50,000 mesh. These diamond pastes are to be used with the three
6" Polytex polishing pads. Once the gemstone material has been sanded and polished with the 3,000
grit (6 micron) diamond wheel, remove the paper backing on one of the Polytex pads to expose the
adhesive surface, placing it firmly without creases on the foam rubber convex surface of the 6" end
polishing disc on the right end (Fig 13).

Lightly smear with your fingertip a small amount of diamond paste on the center of the mounted Poly-
tex pad with the polishing disc rotating. The diamond paste will evenly spread over the surface of the
Polytex pad once polishing of the gemstone starts. No water or extender fluid is needed to effectively
disperse the diamond paste from the syringe to the Polytex pads. Move the gemstone in a rocking
and rotating motion from the center of the disc toward the outside edge to achieve a uniform polished
surface.
Use only one dedicated Polytex polishing pad with each respective diamond paste syringe (i.e. keep
a labeled Polytex pad for the 8,000 grit paste in a zip-lock bag labeled 8,000 grit). Do not use a single
Polytex pad with two or more diamond pastes or else cross-contamination and poor polishing of the
gemstone material may result.
The Polytex pad can be removed from the convex polishing disc by slowly pulling the Polytex pad off
the disc. Place pad in a zip-lock plastic bag properly labeled with the syringe paste diamond grit size
for future use. If the adhesive backing becomes weak with repeated use, you can apply a few drops
of 3M On/Off cement to improve the adhesive connection to the foam rubber disc.
