1858 Pieta NIB Cylinder in 1/2 cock
« on: July 04, 2022, 09:22:48 AM »
Got this several years ago never used, was thinking about a conversion cylinder, taking the cylinder out and putting back problem with getting it back in hard to line up. When I got the cylinder back in, in 1/2 cock the cylinder just spins, this not right. 

I think it is a hand spring problem, am I correct, or is it the hand?

Another question, what caliber would be recommended?  Looking at 45LC or 45ACP, I think 44-40 the barrel is too big.

Thanks

Your assessment sounds right that it is probably a broken handspring.

As to caliber, 45 ACP and 45 Colt are both .452. I don't know about the bore on a Pietta but Ubertis I've seen work better with .454 soft lead bullets.

A 45 Colt cylinder will give you more options. Some will allow 45 Schofield rounds, as well. If you want even shorter cartridges, the Cowboy 45 Specials, which are the same length as 45 ACP, will work in 45 Colt chambers and I've heard at least one shooter say he uses .455 Webley in them. You can also shorten the 45 Colt cases to the length of 45 Schofield and still have historically correct rounds because in 1878 the US Government changed the official specifications for 45 Colt to the same length (1.1" instead of 1.285") so they would work in Schofields, too (the head stamping still read 45 Colt).

45 ACP chambering will only allow 45 ACP rounds.

If the cylinder advances when you point the gun down and cock it, but does not advance when you point the gun up and cock it, that would confirm the hand spring is broken.

The gun cocks fine both up and down, the problem in 1/2 cock loading position the cylinder spins free not stopping at the loading notch.  The cylinder spins like the Ruger Vaqueros, made in larger frame guns back jn 1989.

  Bolt spring?  is my guess, weak or perhaps loose?

If you reload you can get 45 Auto Rim brass https://www.starlinebrass.com/45-auto-rim-brass

Got it almost apart, how do remove the Hammer and Hand does it slide down does not want to go in that direction, hammer too wide, do you remove the hand screw that screws into the hammer?

Glad you mentioned that. I wasn't thinking but that's something to check.

The bolt should not be involved at half-cock.  Broken bolt spring would allow the cylinder to spin with the hammer down or at full cock.

I have lot of 45 ACP factory loads and once fired brass and only a few 45 LC. I must have sold all 45LC Brass or lost it in the move.  I just got a 2nd Generation Colt in 45 looks like I will be in the market for 45's.  So I assume the best option would be the 45 LC Conversion Cylinder?

Got it all back together, everything looked correct, so I just increased the tension on the hand spring, hope that will correct the problem.

Thanks for all the quick replies, greatly appreciate it.  Happy 4th of July to all!

Well no go it still spins in 1/2 cock, but now I hear a faint clicking, I guessing the hand is too short?

What do you think?

If the gun cocks and locks up fine, I wouldn't mess with the hand.  It sounds like your hand spring is still too weak.

It was the hand spring, got her to work stops at lthe  loading notch weak but stops.  Looking at all my Colt SAA 1873 type the springs are all different.  Does anyone know what the hand spring S/B and post a picture of it.

Again, thanks for all the help and have Happy 4th.

I've had good results with handsprings made from piano wire. This one is .028 or .032, I believe. I just flatten the end and install it in the same groove as the original flat spring. I've never had a piano wire spring fail.



If I break a bolt spring, I replace that with one made of .050 piano wire. it's tough stuff to bend but when the job is done, they are more reliable.



Sorry I don't have photos of Remington parts with them but the methods are the same.

Here's a video on installing piano wire springs another way.
