A customer asked me to mill series of flat, disk shaped pendants an
inch in diameter and about 3 millimeters thick, with recessed areas.
The models will be cast in pewter and detailed with enamel.
A “U” shaped jump ring as thick as the pendant was specified for
purposes of strength and durability.
I suggested that a traditional round jump ring, about 2 mm thick,
slightly embedded into the disk, would probably be adequate in terms
of strength.
Not being extremely familiar with casting in pewter, I have what
seems like a very basic question.
Are there any pros or cons to using a “U” shape jump ring as opposed
to a round one, and must it be very thickly proportioned, or would it
be more of a stylistic choice?
Thanks,
