Thinning down a frizzen spring

[ZUG]

It's your spring and you should do as you like with it. If you want a back-up spring then do modify that replacement spring to fit.
You will need to reshape it - close the bend down some this will require heating the spring to red heat. When you get the proper shape then you will need to re-harden and temper it. Thin the leaves using a grinder or Dremel but keep a container of water handy to cool the spring. A fine file can be used and then then some abrasive paper/cloth should be used to remove the file marks. A lot or work but it can be done - good luck.

When I bought a new frizzen for my Pedersoli .32 Kentucky rifle, I also got a new frizzen spring. The problem is, the spring is way too thick and is too heavy on tension. What's the best way to thin these down and reduce the tension on one. The photo shows the spring the gun came with and the new spring to the left.

I have approached this by reducing the width in the spring legs rather than the contour reducing the leg thickness.
