Hi Jeff,
What is the best tool or tool shape for bezel rolling 2mm to 4mm stones?
I would say that it depends on what gauge of metal you’re trying to
turn. Although, with small stones like the ones you mention, the
metal is difficult to turn onto the stone without some sort of
persuasion, whatever the thickness of metal. I personally use a
bezel pusher (flat faced) and chasing hammer. It takes practice to do
it in such a way that you don’t use too much force and leave tool
marks or crack a stone, but to use enough force so as to turn the
metal sufficiently. It becomes second nature after a while.
I would also like to know if it is possible to remove flat spots from a bezel without scratching the stone.
That depends on the stone. Yes, if the stone’s Moh’s rating is
higher than that the tools steel of whatever file you’re using and no
if the Moh’s rating is less than that of tool steel. At least that’s
what my logic says.
