Thinning down a frizzen spring

[David LaPell]

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.

Why not use the old spring, save some work and the new spring or is it weak?

I'm asking in case anything happens to the spring that's on it, I can just swap out springs.

Sounds like a plan.

I grind or file my springs. You can thin or narrow the top section. Stay away from grinding the sharp bend on the front end. Never get the spring hotter than your fingers will stand. Always grind length wise. Make sure all scratches are removed. Left in place scratches/gouges 90 deg. to the length of the spring will cause failure. Always error on the skimpy side when doing removal. You can always take more off, but you can't put it back.

Although time consuming you can oil stone the spring down.
Knife sharpening stone....very fine
Like Larry stated above.....
It,s less aggressive does not involve overheating the spring and you can control the "tune" of the spring to your liking.

WOW, that spring is almost as thick as the hammer!

Why are you replacing the spring ?besides that’s the wrong spring for that lock.

Why have you convinced yourself that you need a back up frizzen spring? The spring on there should work just fine. The only way It could accidentally break is if you compress too much. You should almost never have to take the lock apart anyway.

Like that old saying curiously got that cat killed

I believe he indicated it was a backup.

Because it's so thick that neither of my mainspring vices can even compress it. It's also so thick that it doesn't properly line up with the hole for the screw to fit the spring to the lock. It actually contacts the bottom of the pan too much.

Tell Pedersoli that. It's a Kentucky rifle and that's the frizzen spring they sell for it. I know what the spring on it looks like, but this gun was made in 1984 and sometime between then and now, they changed the way their springs look. I've checked with them and three retailers and even seen pictures of Pedersoli Kentucky rifles out there for sale right now, guess what, THAT's the frizzen spring that they have and the only one Pedersoli offers. If you can find me a spring from 1984, let me know and I'll get that one.

Here's a new Pedersoli Kentucky rifle and there's the same frizzen spring.

That new spring was made for a jack stand for changing brakes. Like said, use the old one.

Why do you want a back up spring? You’ll have to balance it, fit it etc if it’s not broke … don’t break it trying to fix it

It looks to me from the pics the main problem with the new spring is that its bend is too wide open, and so the new spring will have too much pressure for the frizzen to operate normally, and that you're not going to be able to thin it enough to compensate for that. I'd just stick with the old spring and throw the new one in the parts box.
