The partner of the earring on the right disappeared and I was asked to make an earring to match it. The owner was happy with a standard pin and butterfy fitting. It isn’t perhaps obvious from the picture but the tube is square section and I could only buy round tube. The solution is to pull the tube through a square drawplate several times to convert the profile. The match was good.
One of the knuckles on the hinge of the clasp had torn through completely and the others were showing serious wear. It’s a really heavy bracelt and buts a lot of strain on the hinges. They were originally thin-walled tube, but I’ve replaced them with proper thick-walled hinge tube. The hinges should last for years and years now.
