Hi Noel, et al;
questions for a Saturday early morning, and no coffee yet?
I would in my humblest opinion suggest to use your pair of pliers
that have a rounder outside edge to them and ream open the top of the
bezel. This will "enlarge" the opening. Do not use a flat jaws..you
will have heavy marks on the outside of the bezel wall. What size of
bur?... a bur that has an almost same graduated angle as the stone in
question....nothing too small! as for the bottom where the stone
will sit use a #009 or #010 round bur to scallop out any "collections
from casting" on the inner seat.
One of my readers suggested using a brass pusher with an engraved
surface using a cross-cut of lines. Would these lines also be
transferred into the gold?
How about using one of two methods, scoring the surface with a
"rough" textured sanding disk or hitting the tip with a rough cut #0
or a #1 file...flat on? just enough so that the tip wont slide off
when "pushing down, or over"!
My friends I am not here to tell you to do this, I am just giving
you other options!!
