I have a pneumatic looping machine, made by Crafford (the laser
welder folks) that I haven't used in over 20 years. I used it to make
earring findings. You stick a precut piece of wire into the machine,
step on the pedal, and it will instantly form a loop on the end. I
would slide a wire coil onto this, then bend it into an earring hoop.
You can easily do 30 pieces per minute on this machine. You will need
a compressor to power it.
We were using 20 ga. wire, and I think there is some tooling for a
slightly smaller wire (or maybe it was for a larger loop...it's been
a long time). Regardless, either Crafford or a local machine shop
could easily modify it to make any size loop using what ever wire you
This may be more production than you need, but if you are
interested, let me know.
