Smell of pyrodex in the morning

Problem with Uberti Remmy. When I got it second-hand, it had a real nice trigger - couple pounds pull and zero creep. But after a few outings it has gradually become a 'hair' trigger. I'm not joking when I say you can 'think' it off! It doesn't to release when I smack the butt though.

I've tuned some triggers but never un-tuned one.

Should I stone the sear notch it a bit deeper or buy a new hammer?

It could be the angle in which the tip of the trigger & the sear of the hammer have in relation to each other too.

The sear angle is also important in the feel and safety of the trigger. When the trigger and hammer sears interlock, if the sear is on the radius line of the hammer, then the angle is zero or neutral. This means that the movement of the trigger does not move the hammer at all as the trigger is being pulled. A positive angle means that pulling the trigger causes the hammer to be cocked slightly more as the sear must move the hammer in order to clear. This slight dovetailing of the sears should be at around 2-3 degrees to provide a crisp trigger that will be safe and hold well. Any greater angle is an over-engagement and creates an excessive trigger pull. A negative angle is unsafe because there is no interlocking of the parts and the trigger can release the hammer without being touched.
Whenever working on the sear, I recommend that the hobby gunsmith reassemble the gun and test the trigger for safety. Put the gun back together without the cylinder. Cock the gun to half-cock and then put pressure on the hammer and try to push it back in the direction of the frame. It should not move at all. Assuming that the hammer holds well in the half-cock position, pull it back into the full cock position and repeat the test by pushing on the hammer to make sure the sear is engaging and holding. If hard finger pressure on the hammer causes the sear to slip, then your gun is not safe and the sear angle is probably negative or the sear is way too short. You should find the break to be crisp and clean. If you are used to cartridge revolvers, the trigger and hammer pull may seem a little strong, but this is normal in a cap and ball revolver since the hammer must place pressure on the cap during ignition.

I've gotten this info off the net "The writer is Mohave Gambler" that reflects nearly exact word for word of what a friend of mine has written & given me a copy of more than 18 years ago & I've used as a basis for tuning SA revolvers since.

Hope this helps.
 
KNUCKLES ? what the heck is that?:confused:
HEY bin shooting my remmys for years never
busted my knuckles. that jim shockys gould
man you can keep that ***%* you could not
give me that stuff, i will stick with the real stuff
BLACK POWDER. i shot some balls with that jim
i can hardly bring myself to say it shockys my
remmy went on a sick binge, give her some bp
she said thank god for that.:D
 
Before I jump in...

I've been testing the trigger on my Uberti '58. It's pretty amazing.

Zero creep and less than a pound trigger pull. Bench rest guys would kill for it.

AND, It doesn't go off if i push it toward the frame, slap the butt and muzzle or even drop the piece a foot onto a carpeted floor. I hate to mess it up.

I'm going to try increasing the spring pressure on the hammer and trigger and see if that will increase the pull weight. if i could get it to 2 or three pounds it would be manageable.

I'm worried it has a soft sear--maybe the previous owner did some filing. When I first shot the rev., the pull was nice -- about 3 pounds-- and no creep. But everytime I shot it, it seemed to get lighter. The only lube on it is mineral oil.
 
awsome

my firts blackpowder gun was a rem. 58 and it was the most fun i ever had with a gun ,so i went out the next week and get a colt 1860. and it was great too where has this been all my life ?
 
I had a group of students shooting for qualification Friday. I brought my 1858 Pietta along for "me" while waiting for students to show. Well, They used up all my powder and went away with a smile after shooting better (in almost every case) with the C&B. And I only shoot BP. I have some of those imitation powders and will be trading them away at the 1st opportunity!
 
Worked on the trigger/sear

It could be the angle in which the tip of the trigger & the sear of the hammer have in relation to each other too.

I shot the Uberti '58 again today just to confirm the trigger is that light. It was and after two cylinders, I gave up. I had two shots go off when I was positioning my finger on the trigger!

I tore it apart this evening and examined it through a loupe magnifier. Sloppy machining was abundant. First, the angle was barely 90 degrees to the hammer pivot point. But a burr on one end of the sear surface was all that was keeping the hammer from slipping. That explains why the pull changed so quickly over about 100 rounds.

With a lot of reassembling and checking, I filed/polished an angle into the sear surface.

Now, I've got a 2 pound trigger. BUT I ALSO HAVE A LITTLE CREEP:(. But I think it will be unnoticable when firing freehand.

I also may have removed the hardening, I'll just have to see how it wears.
 
If you filed it it wasn't hardened to start with. You can get some kasenit from Brownells and harden it.
 
Hawg's right. If you were able to file a new angle on the trigger the hardening is gone. My experience is that it's very shallow at best, and it sounds like yours may not have had any at all - 100 rounds should have just started breaking it in, not changing it's pull.

Get some Kasenit or a new trigger. That one is shot.
 
I agree 100% about the hardness of your hammer since you filed it.

What I would suggest is if your 58' is timed right & the lock up is good & with just deepening the sear on the hammer improved the trigger engagement but not have it engage too early "sooner than the bolt stopping the cylinder" then get some ultra fine stones to smooth up the sear but not take off any more metal than necessary to make it glass smooth, then get some Kasenit & heat treat your hammer at the sear.

It's a two step process.
(1) Heat the part to where it is a glowing cherry red hot, dunk the hammer into the Kasenit to coat the sear area of the part but no where else "at least no more than you want to show when it is assembled because this will take all color from the part & give you a greyish case hardening when done" then reheat the part to a cherry red glow then dunk it in a 50/50 of Water & oil to harden it.
(2) once the part is cool, reheat it to a slight yellowish glow but no more than that "about 900* F" then let the part sit to cool on it's own.

After that your hammer will be hardened & tempered perfectly for years of use.
 
Sheesh.

At $42 for a new hammer, it looks like Kasenit is the way to go. But what a hassle. I expected the Uberti Cimarron line would have better QC. It didn't look like the original owner had been fiddling, so it must have come soft from Italy.

BTW, does the pretty case-hardening color on parts mean anything functionally?

Looks like I get an education in metallurgy.:o Is it possible to get Kasenit anywhere but Brownell's? I'd like to avoid the shipping hassle/cost.

Today 08:30 AM

Dixie Gunworks has a hammer for a Remington reproduction for $17.00 but as to how much fitting you may need to get it to work on your Uberti is unknown, VTI has em for $42.oo... :(

The Color Case Hardening works the same way as the Case Hardening procedure with Kasenit but the materials used in the process is what gives it that nice coloring.

You can get a small ammount of Kasenit from Dixie Gunworks

You can also get a 1 pound can of Kasenit from
Track of the Wolf
 
Tnx OldWheat!

I PMed you.

FYI, a hammer is $45 direct from Cimarron.

I was dry firing the Uberti '58 (put a roll of leather under the hammer) and the trigger pull feels pretty nice right now. So, I think I'll make a sacrifice to Vulcan and go the DIY Kasenit route.

Thanks, everyone, for the info and onward into the fog.
