I am trying to refine my prong setting techinque andhave realized
that I don’t really know what is the proper size bur to use for
notching prongs. In the past I always used a small (like 1.5 - 2mm)
90 degree hart bur but it took a lot of moving it back and forth to
notch out a decent seat for the stone and I wasn’t always satisfied
with the results. Now I’m wondering if I should be using a bur that
is closer to the diamater of the stone so that it makes a cut that
is closer to the circumferenceof the stone for a better fit.
Also I’m thinking of buying a prong cutting guide to control depth
and height. Any recommendations?
Thank you all
