Airflex Wheels
Airflex wheels are made of a special material that has thousands of miniature air pockets
throughout that keeps the heat from friction minimized. These wheels last longer and won’t
“burn” the metal being worked on. The Airflex Medium Green Wheel is particularly excellent for pre-pol-
ishing platinum. Doug Zaruba, well-known goldsmith and instructor, tells us that he loves the
Airflex Medium Green Wheel for this purpose, as it saves him time in preparing platinum for               G
a final polish, leaving a finish similar to a 800 grit paper. Available in three grits, Airflex wheels
are long lasting and are also excellent for surface preparation on gold and silver.

stones can be a problem even for master setters. Pumice wheels are a great solution, as they will remove
metal without damaging most stones. Their end result is a fine finish that requires only a little buffing to

            your stone, check it first on a piece of glass. Glass is 5.7 on the Mohs scale. If the abrasive wheel doesn’t scratch the glass, then you know
            that it won’t scratch most faceted stones. Don’t forget that even a delicate pumice wheel can damage a weak facet or girdle, so be to
            check your stones with a loupe before setting and finishing. If you’ve got a cabochon, consider testing the effects of your abrasive wheel
            carefully on a small place on the back of the stone. Remember that pumice is around 6 on the Mohs scale, so very soft stones like pearl,
            coral and amber will certainly be damaged by most abrasive wheels. Test first, don’t be sorry later.

                   Trizac is an aluminum oxide abrasive that cuts stone and metal uniformly. The pyramid shaped abrasive produces a finish similar to file strokes, but
                   with a lot less effort. Minimum order is 12 pieces, but your best deal is when you buy a pack of 100. Maximum speed is 10,000 RPM.

carbide and brightness enhancers. The wheels are shapeable making them capable of reaching maximum finishing efficiency with
a wide variety of shapes and surfaces. They are a perfect addition to the family of 3M™ finishing products, which reduce, if not elimi-
nate the need for traditional fiber buffs and messy polishing compounds.

           You can change the shape or re-true the 3M FX polishing wheels with something as
           simple as a sanding stick. While the wheels work fine with regular buffing machine
           speeds (3450 rpm), they will last longer if used on slower speeds (1725 rpm). The
           wheels work great dry, but they also have the option of being able to be used wet.
           Consider on a lapidary grinder which will eliminate heat build-up.

                   Artifex wheels are the best quality conforming abrasive wheels that you can buy. Nothing beats them for consistent, seamless finishes on all sorts

                   scratches on hard metals while leaving a burnished surface that is ready for a final polish. Made in Germany.

                   Airflex wheels are made of a special material that has thousands of miniature air pockets throughout that keeps the heat from friction minimized.
                   These wheels last longer and won’t “burn” the metal being worked on. The Airflex Medium Green Wheel is particularly excellent for pre-polishing platinum.
                   Doug Zaruba, well-known goldsmith and instructor, tells us that he loves the Airflex Medium Green Wheel for this purpose, as it saves him time in
                   preparing platinum for a final polish, leaving a finish similar to a 800 grit paper. Available in three grits, Airflex wheels are long lasting and are also
                   excellent for surface preparation on gold and silver.

   Abrasives

                   3M makes the best performing abrasive paper in the world. Micron-graded abrasive means a consistent, uniform
                   grade of material is bonded to the surface producing a consistent uniform cut.
                   If viewed under a high powered microscope, 3M abrasive paper looks uniform in shape, without the high and low
                   variations that come with conventional papers. Those variations in conventional paper can produce inconsistent
                   results, but not with 3M micron-graded abrasive finishing sheets.

    38             Emery Paper and Mitchell’s™ Cord & Tape
                   Jewelers have relied on emery paper as an abrasive because of emery’s unique characteristic of constant uniform
   Abrasives

                   grain structure. Emery paper will give a reliable, consistent finish with a minimum of microscopic high spots that
                   can cause deeper scratches than anticipated. We sell 2 brands of emery paper. Sianor™ Swiss-made emery paper
                   range from a very fine 8/0 to a coarse #3. Norton™ American-made emery paper range from 4/0 to #3.

Ruby abrasive stones are made from sintered crystals of synthetic ruby. They are extremely hard, maintain their shape well and are
resistant to wear. Because they are so hard they can sharpen and finish extremely hard metals such as carbide gravers, but also work
on non-metal like glass, porcelain and quartz.

   Abrasives

                   Slip Stones are used in jewelry similarly to how one would use a metal file, which is
                   why they come in so many shapes and sizes. A big difference between a metal file
                   and a slip stone though is that any surface of the stone can be used to do the filing,                               A
                   including the point. They work best if used wet and through use will conform to your
                   metal surface. They are especially perfect for getting into tight places and in situations
                   where back and forward motion will benefit you more than rotary motion such as                                           B

Belt sanders are great tools to have in the workshop, speeding up
grinding and finishing jobs while allowing you to use both hands
so flat surfaces are easy to achieve. The problem with belt sand-
ers for jewelers has always been that the common industrial belt
sander is just too darn big for the average jeweler. Kate Wolf has
solved this problem by designing a jewelers sized belt sander that
is just right for the jewelers bench.

The Kate Wolf belt sander is a compact design that uses 1” wide
3M sanding belts and easily connects to your flexshaft for power.
It can be used mounted directly to your bench with the included
clamp, or fitted to your GRS benchmate with an optional adaptor.
The Kate Wolf belt Sander also includes an attachment for hook-
ing up to a dust collector, to help remove dust particles. This is
a great little tool that has been perfectly designed for the bench
jeweler, helping to speed up polishing and grinding applications
for your creations and your tools. Just a quick zip zip on the belt
sander, and you’ve just saved yourself lots of time compared to
hand finishing.

The Kate Wolf Belt Sander uses belts manufactured by 3M, so
you can get all the great 3M abrasive products like 3M Trizact
tm, Regal tm, Xodust, Imperial Microfinishing Film and Diamond Microfinishing Film. Putting these advanced abrasive on your
bench is just one for reason for making the Wolf Belt Sander indispensable for the jeweler. The Wolf Belt Sander Kit includes the
Wolf Belt Sander with standard bench clamp and five ruby belts, one each 80, 120, 180, 240 and 320 grit. Options include the
adaptor mount to fit your new Wolf Belt Sander to a GRS BenchMate tm, and a huge selection of 3M belts.
