I’ve had a few orders for these precision machined rings. They are an enjoyable but challenging part to make. The material is a copper-nickel and it’s quite “sticky” and produces a lot of heat when machined. The chips in the header picture are actually some of the drillings from the first batch. The part also had a required tolerance of +-.002″ on the length so I had to be very careful parting them off.
