To get the best weight from some stones that I facet, making a
bezel or prong setting from scratch, fabricating or revamping and
existing setting to fit these oval shapes, gets old really fast.
Faceting for maximum weight means that you are not producing a
calibrated gem. Apparently you are convinced that making a mandrel
for each non-calibrated gem is a solution for the time spent making
or modifying an existing setting.
I do not comprehend how spending the time as a machinist is less
boring as you would be making oval mandrels over and over for each
gem unless you are gaining benefit by becoming more skilled as a
machinist and that is what is valuable for your needs.
I usually make tools that are used for processes that are repeatable
or for a one time use when nothing else can be used. I do have to
incorporate the time making a tool into the cost of doing the work.
How do you incorporate the cost of the time you take to make the
oval bezel mandrel into the price of the gem? Am I correct in
assuming each oval mandrel you make is used one time for one gem?
