How do you reset a leaf spring ?

[StuP]

So, after a few hours filing and milling my repro sear spring is close to fitting.

The big challenge I have is how to set a curve on the arm to approximate the original. Can you heat and bend ? I kind of feel I'll lose the 'spring', (temper ?), if I do that.

The leg I need to bend is ~ 1" long

Rabbit2047 may be able to give you suggestions.

You need to aneal it, bend it, and then heat treat and quench it to regain your temper.

Gotta do it just right, too soft and it bends, too hard and it snaps.

Is this a non replaceable part?

Even though you might get it straight the chance of getting the same spring rate is very, very very low.

No, this is a repro spring, not cheap, but replaceable.

I need to put a curve in it to mimic the original pictured. Replacement's needed as both legs have taken a set, (both act as springs for different functions, the short leg has been fitted and works perfectly).

The rate isn't hyper critical, it tensions the sear / disconnector, it doesn't move much and I'm willing to experiment. It's pretty stiff.

I'm not impressed the repro contour is so different, but you have to work with what you can get !

Roger that! Won't hurt to play with it if you get another.
