Make your own custom springs and measure them correctly

[Murph1090]

Joe, if you're using spring steel wire or the like, you should be good as is. You can always put the spring in a oven at 500 deg F, let it come up to temp, and let it cool down slowly in the oven. That's a common process for magazine springs that have been in magazines left fully loaded for years. Streach them out to full length, heat treat them in a oven, and you're all good again.

Larger springs can be made with softer steel, and hardened and tempered afterwards, or hot formed and tempered afterwards.

Flat springs are their own animal - the large ones for pistols and the like are formed and polished, heated up and quenched to harden them, re-polish them, and set them on a mix of motor oil and sand, light the motor oil aflame, and let it burn out and the spring cool down. Should be good at that point - should!
