I finally got to shoot my new to me 1851 Pietta yesterday. What a hoot! Loud noises, smoke, fire, every kids dream come true.
First, thanks to everyone here for the good information and attitude. Some forums make a newbee feel unwelcome, but not here. A special thanks to the folks who went to all the trouble to post the information in the sticky. Couldn't have done it without you.
I have two small problems. I can't seem to get the caps fit on the nipples tight enough to fire every time on the first strike. They always fire on the second time around, so I'm sure they're just not seating good. Any tips on that?
Next, and of larger concern, the cylinder doesn't always lock up. If it's clean and I pull back the hammer with enthusiasm, it clicks in just right. After a few shots, or if I cock slowly, the cylinder needs to go just a tiny bit further to lock up. I think it's hammer cam, bolt fork, hand fits, but I'm not sure where to go looking. I did notice a rough spot on the hammer cam when I cleaned it, but I need some advice before I go banging around.
 
Try different size or brand caps. Sizes are not actually standardized as well as one would think for 2012.

Some folks seat their caps more firmly on and down on the nipples using a soft wooden dowel or a pencil with an eraser intact using the rubber end. Check out some of the posts from Duelist1954 for links to his various C&B demonstration and test you tube videos to see what I mean.

I would try that first but that cylinder should rotate fully until the cylinder stop clicks into place. Possibly the hand isn’t reaching up far enough to rotate the cylinder fully. Taylors and Company has replacement hands for the Pietta revolver and you may have to do some home repair. I’ve done it before But I’ve always kept the old hand as a guide to shape the replacement hand. You don’t have that luxury. Good luck.

Wow 45+9, you win.
I called them parts somethin outlandish myself a while back but you got me beat 'hand's down. lol You left out 'thingy' tho.
Jist funnin with ya and i assure you i mean no disrespect.
I jist like the sounds o' the way you worded this.

There are two PDF links in here somewhere that you can print out and they will guide you thru tunnin yer timing. I can't recall where they are. I just printed them and never looked back.
I believe that maybe Mykeal posted them when i needed them.
Maybe he'll chime in here or you could PM him and ask.

Hope ya didn't take no insult from me 45+9.I certainly dint mean none.
 
could just be the little spring on the hand needs bent just a little [very carefully] i had a similar problem on one of my remmies and that fixed it, honestly the 1851 desig is really quite simple and fairly easy to figure out, you can get a intire kit from cabelas for 45 bucks, money well spent, pghrich
 
Huh? What? Somebody call me?

Darn it, Jim. That was one fine dream. Sweet thing had her hand out reaching for me, and the next thing I know your ugly face is calling me. You could hurt a man doin' like that, son.

Ok, let's see here - tuning articles - probably the Pettifogger stuff - fine work, that.

Damn, that's one big moth. How'd he get in there?

Aha. Here they are:
Tuning the Pietta, Part One
Tuning the Pietta, Part Two

Caps not firing on first strike - two possible causes: 1. caps too small, probably CCI No. 10's. Use CCI No. 11 or either of the two Remingtons. See, nipple cones are tapered, caps aren't. Caps are designed to slide down far enough that the explosive material on the inside comes in contact with the nipple tip just when the opening diameter of the cap matches the diameter of the nipple cone. However, you don't get 3 decimal place accuracy for 4 cents, so sometimes a batch or two won't exactly fit. If the opening diameter is too small, the cap will stop before the explosive material settles against the tip of the nipple cone. Plus, CCI and Remington and the nipple makers didn't exactly coordinate dimensions. CCI No. 10s are NOT the same size as Remington No. 10s, (neither are the No. 11s) and while the CCI No. 10s are indeed smaller than the CCI No. 11's, Remington didn't see fit to follow that convention, and their No. 10's are actually bigger than their No. 11's.

Possible cause No. 2: nipple tips are deformed. You may be able to feel a little ridge around the tip of the nipple (usually cause by dry firing - do not ever dry fire a percussion lock or revolver without cushioning the nipple) with your fingernail. Chuck the nipple up in a drill motor (use the nipple base, not the threads) and run an emery board or fine file against side of the cone at the tip. Run the drill motor SLOWLY. Should get rid of the ridge and smooth up the nipple cone. Try this even if you don't feel the ridge.

Now, where was I? Be there in a minute, darlin'.

Sweetie, where'd you go? Yoo hoo, cutie pie....
 
yep, dam's da articles alrighty !!
I knew dat you knew dat and knew dat you could do dat Mykeal.
