I am looking for a source of pre-cut sterling ovals
approximately 11mm long in 24 guage.
It sounds as if what would be the best process for this sort of
thing is to saw out a simple blanking die. You saw the pattern
one time in tool steel (it is annealed and not hard to saw) and
then you can make as many parts as you wish. Properly sawn, there
is no clean-up of the edges and minimal burr as the die wears.
With this process you can blank out several hundred earrings. For
some sketches of the process, go to my webpage and in the Learn
section, go to “Combined matrix/blanking dies”.
