Pietta 1858 NMA question - Page 2

rem1858 · January 7, 2011, 10:04 PM

Thanks for the info

So to get this straight...
What I have is a 1991 Pietta that someone reworked the cylinder to produce a gas ring and machined the barrel to set it back and then reblued it all for competition purposes ?

Neat

I will not mess with it, just shoot it.

You got it straight. Enjoy your custom gun.

Took the 1858 apart this afternoon cause the cylinder latch was messed up.

Found the little machined button on the hammer is worn out and the cylinder latch slips past it and will not hold in place.

I have the parts kit from Cabelas.

Will need to machine all the parts to get her timed correctly.

I have reworked some DA's in the past, but will be my first SA.
My next project

Oh, mykeal;
You mentioned that it is a parts gun cause none of the numbers match.
Well, after stripping it down completely today I found something interesting.

At the bottom of the grip on the outside has ser# 127494
The rear of the cylinder has 494
The grips have 494

With the grips off a stamping #PF0262 on the frame next to the hammer spring.
On the bottom of the barrel 262
Inside the brass trigger guard 262

Very unusual for the cam on the hammer to "wear" out. It may have been oversmithed. If indeed that is the problem I'd suggest just dropping in the new hammer from the parts kit and trying it before I started replacing other parts. Just a suggestion.

That cam is tapered, maybe the bolt leg is bent.

mykeal · January 9, 2011, 09:03 PM

Hmm. This is 494?

rem1858 · January 9, 2011, 09:03 PM

Denster;

If you saw what I saw when I took it apart, you would understand.

All of the parts look to be original with a lot of wear.
I think this gun has seen a lot of action in its 20 years.

Installed the new hammer with the old cylinder latch and it works.

Thing is the hammer hooks for half cock and full cock on the new hammer have to be machined a lot.

It will go to half cock at 3/4 travel of the hammer.
It will not go to full cock at all.

So I decided that I will just install all of the new parts and take my time to get everything just right.

Nice project for me in my spare time.

I will be shooting the ROA for awhile now

I may post some photos of the old internal parts.

you got me there

well, anyway, the rest of the numbers match

so it is not a total parts gun

Just an observation. The hammer cam does not appear appreciably worn however the bolt (cylinder lock) is shot.

rem1858 · January 9, 2011, 10:41 PM

I know that it appears that way...
But, with the new hammer it works.

The cam is worn just thin enough that it starts to lift the cylinder lock and slips off.

A better picture would show the difference in the thickness of the cam.

I could probably get it to work again with some love and care, but it would eventually do the same thing again.

Time to set it up to go another 20 years I am afraid, but not.

Good luck with your rebuild.
