This picture shows how nicely the wire coiled to make a spring. Once each run was completed the rod was removed from the chuck and the new spring slid right off. I then marked each 10 coils with a sharpie and cut with a cutoff wheel. I still need to finish grind each end and debur the hole but otherwise I believe they will work.
Total cost is about $50 which was for materials only. Total time to set up the lathe and make and cut over 100 ferrules is about 3 hours.
