Maybe flat ground stock? https://www.engineeringsupplies.co.uk/1mm-x-10mm-x-500mm-metric-gauge-plate.html Too thick, but could be surface-ground. Depending on the displacement you might not have to harden it. Hardening doesn't make the material any stiffer, it just means that it can bend further before the elastic limit is reached, 0.6mm is thicker than clock springs: https://www.ebay.co.uk/itm/224266845701 Is thinner and wider an option? High performance spring steel strip is hardened by cold-rolling, not by heat treatment. When I was working in spring steel development I could have rolled you some to your specification, but that was a long time ago. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
