mod 629 out of time

[mod15]

I have a model 629 44 mag. It does not quite engage cylinders on 2 notches when cocking real slow. It appears that the rachette should be peend slighltly on the 2 appropriate lugs to thicken them so hand will move them a tiney bit sooner. Has anyone actually done this and were you succesful?
I can cock it back fast and the cylinder stop will engage those 2 cylinders but not if I do it real slow That just bothers me so I want to fixx it so no matter how slow I cock it , the stop wil go into the notch on all 6 cylinder notches.

hold up

Do not peen it is a one shot deal if it is screwed up. And most do.

Check the hand for abnormal wear or trueness, S&W can replace the hand if thats all you need,

has anybody worked on the gun in the past, how many rounds etc

Is the cylinder stop working properly(Spring etc)

abnormal wear on extractor star

Dirt, gunk in the action, crane etc

I recommend a good cleaning, and if you have a problem I would send it to S&W

I took gun all apart and checked everything and completely cleaned polished and relubed the innards Then I tried it again and still no change the 2 cylinder notches still dont quite make it to the stop. Hoever all 4 of the others do.That's why I think it is in the racthet(star) But I am leary about trying to peen it. But I do want to learn how to do these things myself. Thanks for your response and any other input you may have.

I wouldn't peen the ratchets, just replace the hand. I bought a 625 that was slow on one chamber, and that's all I did (replaced the hand); I can live with the other 5 chambers locking up a little early if it means that the one chamber locks up on-time (and thus becomes usable again).

gap

Did you check the cylinder gap between the forcing cone and the cylinder
on the 2 that would not lock up to the 4 others,is there any difference sometimes 2 in a row is a hint it could be that. without seeing the gun, it is something I would check hope this helps

That's a good point. I think I will look for a new hand first and see how that works out. Thanks!

I did not check with feeler gages but now that you mention it, I am going to.Are you thinking that maybe there is a very slight rub that keeps it from locking on the 2 cylnders? I gues that is a possibility Thanks

I only peened one gun. It does work, but it looks ugly forever after.

Install a wider hand and then balance the ratchets so they all carry up the same (correct) amount. It's normal for a couple of ratchets to be different than the rest because SW doesn't balance them as well as they used to.

no rub

no rub, but a slightly out of line cylinder, (maybe)

Remember the cylinder on the 629 is larger than a J frame and a K frame
it takes more energy to rotate to lock up.

check the gap, if not, I would sleep better if I sent it to S&W,

If you have barrel cylinder clearance all the way around then be sure you have empty cases in the cylinder when you are cocking in SA. The large cylinder takes momentum to turn and the cases add weight. If you cock it like it was designed, I bet it locks into the notches. It was designed as a tool and not a precision machine. Never peen the ratchet or you will screw up an expensive part that is factory replacement only. You can change the hand, but then you might need all the ratchets cut. I bet it is within specs.

 

[mod15]

Can I possibly take out the hand and pound it flat side down to make it longer? so it pushes cylinder a little further??

 

[sal1911a1]

no

no pounding, you have other cylinders to think about, 4 are working fine
You don't need a new hand


The problem most likely is in the extractor star ratchet, maybe some burr removed by use or do you observe some peen on a stud.


This is something for a gunsmith with the right tools and knowledge in your area or send it to S&W

The action in a S&W depends on the width of the hand, not the height.

YouTube - Gunsmith - How to repair slow timed Smith & Wesson revolver -- check out this video; Larry Potterfield of MidwayUSA explains how to fix it. Note where he says the oversized hand is a few thousandth's wider than the original hand.

Ok.I guess I had the older colt hand in my mind.

Actually, what some smiths do is bend the tip of the hand slightly to the left, but you have to torch heat it to bend it or it will break off (it is very brittle from hardening)

hands don't cost enough to make that worthwhile.
