I want to make cable chain and the steps I have trouble with are marking or finding oval or close to oval shaped spindles for when you wrap your annealed wire uniformly. I have found brass round stock and I run it through the rolling mill to flatten it out into a nearly oval shape but even when hard brass is used, it’s never tough enough to stay straight like a steel spindle would.
How do jewelers make good cable chain without a steel spindle or do they have machine shops make them for them? I was only turning 2 or 2.5mm thick but dead soft wire and by the time I only turned about 3 inches of the wire onto the brass spindles, the spindles were warped and then the links were not uniform due to the bends of the spindle.
Thanks for any advice. I thought of maybe trying to make my own cold cast steel spindle by using a special epoxy that has steel in it. I could shape it into the size and shape I want but I don’t know if that would truly be strong enough.
