Making jump rings is one of the basic skills for us metal workers.
cutting them off a coil with snips isnt tha best way for the
Jump rings come in contact with skin, snipping them leaves a sharp
burr which will catch, and the customer will complain, meaning more
reworking for you,let alone your reputation.
Also when closing the jump ring you wont be able to get the 2 ends
to line up so well.
The best way is to cut them with a jewellers saw supported on the
rod you wound them on, preferrably a wooden dowell.
Especially if your making jump rings or any rings for that matter, a
close fitting joint is so much easier to solder up. Use a tiny piece
of silver solder foil between the wire ends. flux all over heat.
youll get a perfect joint every time. Especially important if your
working in gold and silver.
when your making thick wire jump rings say 50/1000 in with a 1/4in
bore, for heavy pendant use, then sawing is the only way. As for mas
production of jump rings.
when you have made a minature circular saw bench, with say a 2in dia
by 20/1000 in hss slitting disk, you can cut a coil of say 30 rings
in seconds, using bees wax as a saw lubricant. Also wrap the coil in
sellotape to support the rings once cut.
Mind you fingers tho!!.
