Cabbing Time

It’s cabbing time and so in the cooler mornings we grind stones, (it reached 91 F for the past three days). A front has passed through, and the temps are now down into the eighties. Our humidity is usually about ten percent and so it’s pleasant without needing air conditioning. Each year, after all our shows, we make an inventory of what we have sold. Next we locate the rough rocks and saw them into slabs, (using a slab saw). From there we draw the shapes before using a trim to saw rough shape them into what we call preforms. These are now ready for us to grind into finished pieces, called cabochons, before giving them a finish polish.

To do this we select the preforms and then grind them on diamond wheels. The first wheel has a grit size of 100, wheel two is 220, and the third wheel is the special wheel that we think of as a magic wheel with 400 grit. Thie first two wheels are rigid, but the third wheel has a pliable backing that takes the edges off the preforms and cuts them into their final shape. we grind these by hand, as using dop sticks is unnecessary, (unless the stones are too small to grip, which are used for rings or earrings).

After washing the cabs, we inspect them for any scratches before finishing them. Wheel number four has a grit size of 600, wheel five is 1200 and the sixth wheel is 14000, (we also have a wheel coated with 50,000 diamond grit but it is rarely used.

Finally. we give them a final polish on a buffing wheel. The last step is to inspect them for any flaws or scratches before saving them in glass cases. We only finish about fifteen cabochons every third day, this gives us a few days for my back and hands to rest/recuperate). The cabs are then stored and taken on our winter travels. We turn them into jewelry when the weather is too bad for fishing, birding, or hiking. Clear skies and rock on!. I still enjoy making cabs even though we have made thousands. It’s still amazes me that we can take a rock and turn it into a stunning cabochon/piece. For safety all cabs are ground with water to minimize dust. We do not wear jewelry and also wear a N 95 respirator/ mask, a lab apron, and a safety shield. Our cabbing machine is a Genie, which was made by Diamond Pacific, a company in California.
