Stupid question 'bout heat treating

[J Miller]

I have a theory about something. Why some of the Win 9422s were marked 22 S, L, LR and the newer ones were not.

On my 9422 it fed shorts very well when I first got it and for several years afterwards, then sometime after that it would no longer feed them.
I've had the action completely apart and the only thing I've found worn is the carrier pawl. In the 9422 that holds the carrier up until the nose of the cartridge is in the chamber. But now the lifter falls way too soon.

So my curiosity was, could a part as small as this be checked fore heat treatment?
I don't have a pick of it, but it is very small, part #13 in the pic below.

Instead of hardening make one out today drill rod. It's already hardened.

It would need a flat spot to support a 150kg load the size of a ball point pin for a Rockwell C scale check. That will leave a small divot like a center punch provided it's even in the C scale range.

boolitshooter,

I wasn't planning on building a new one, as far as I know they are still available.


Marvin,
Thanks, that answers the question. I don't think there is enough room to do the test.

Order a new one, then take both to a local machine shop that has a hardness tester, compare both.
Chances are the pawl is/was case hardened or surface hardened.
You could hardest the new one by yourself. Brownells has a product called casenite. Only problem is how to hold it to bring it to red heat, introduce the casenite,quench and polish such a small part.
I suppose you could also get a shop to carburize it as well.
I'm not familiar with this part so I'm guessing it is a common problem if they are available for sale.
Is it spring loaded? Spring could be weak causing it to fall...

Drill rod is pretty soft. I keep a good supply of various sizes for different uses, and it's extremely easy to cut and work. Anything hard enough to not need hardening does not file easy. If I can file metal easily, I know it needs hardening.
Even drill bits can be cut and filed easily on the base. It's the cutting part of a drill bit that is hardened. You can bend the shaft of a drill bit pretty easily.

Joe,
Every guncrank needs this stuff in the gunroom. In addition to gun parts, I've used it for all kind of stuff.------6

Sixgun,

I may just get some of that stuff.

Or if the little part is cheap buy a couple and replace when needed.

Man! I hope not. With this stuff you heat it up red hot with a torch and then stick it in the compound and heat it up again. Whew! That would hurt. ----6
