I would like to offer a couple of suggestions to reduce the
manual effort of bezel setting.
I use a reciprocating hammer tool, it fits on the flexshaft in
place of the handpiece. It takes a few seconds to interchange
The shape and size of the hammer tip can be modified to
accomodate various bezel sizes. I have 3 different tips. After
setting with the hammer, a light clean up with an escapement
file and rubber wheel and you’re good to go.
I like the look of a nice thick walled 14 kt. bezel, so
occasionally I will cut a line inside the bezel at the level
where I want it to roll over the stone. If you look inside the
bezel with the stone in place, you can see where it needs to be.
I use a hart burr to get it started and then a ball burr to open
it up so it doesn’t crease when you shove the metal over. It
doesn’t have to be a deep cut, 1/3rd of the thickness of the
bezel is enough. The idea is to relieve some of the thickness
without sacrificing the look and wearability of a heavy bezel.
The area that is thinned is lower down the stone so it isn’t as
subject to wear.
Hope this helps!
