Some of you asked to see a step by step of the process. First, a slab of polish flint (199 is weight in grams) with the stone I want drawn with a Sharpie, second a piece cut out of the slab with a trim saw, third the piece trimmed on the trim saw, next, the stone ground to outside shape on a 100 grit diamond wheel, next, stone shaped for dome on 100 then 180 grit diamond wheels. Then ground with a 220 and 400 grit diamond belt to remove the heavy grinding marks from the 100 and 180 wheels, then ground to a pre-polish on 600, 1200, 3000, and 14.000 grit soft diamond wheels. Last two are finished stone after polishing with Linde A polishing powder on a wet leather buff pad. There is no sun here today, so I can't get good shots of the finished piece without the reflection of the light bulb. This is the first Polish flint I have done, it has wonderful patterns which seem to have depth when polished. Perhaps tomorrow I will make it into a pendant with step by step pics of that process.

DSCN1628.JPGDSCN1629.JPGDSCN1632.JPGDSCN1633.JPG8" wheel grinder/polisher with 100 and 180 grit diamond wheels, two expando drums with 220 and 400 grit diamond belts and the polishing pad is on the far right. This is a variable speed machine and a little outdated, but in my opinion it is better than the more modern single speed machines. Next is another 8" grinder/polisher, a single speed machine which I mostly use the right four soft diamond wheels in 600, 1200, 3,000, and 14,000 grits, and it too has a polishing pad on the right end. A pic of the trim saw with the little trimmings seen from the stone I just did. A battery of saws, two 10" power feed saws and the 6" trim saw which you manually push the rock into the diamond blade. Last another pic of the finished Polish flint.
