If all is working well I would leave it alone. You could move the clock and set it up and see if it sets itself in beat by just swinging the pendulum as I suggested. If that works then you know it is working as it should.

I probably should know this but what is the difference between 'sets itself in beat' and 'self regulating'?

It is happily ticking away and I can't hear a double tick or tock...

Anyway, I could only really hear the double 'tock' when I used an old stethoscope my doctor friend gave me.

There is no such thing as a self-regulating clock.

A clock that sets its self in beat normally has a friction tight crutch, which can be attached by it being threaded onto the pallet shaft. I have also come across modern ways like the movement you have been working on. Many of those French movements you get in those very heavy slate cases have self-beat movements.

I guess I just made the mistake of thinking a clock that set itself in beat was 'self regulating'...

I take it that, if a pendulum has a friction tight crutch it can set itself in beat little by little due to its being able to move on the pallet shaft in order to allow an even swing.

I noticed that the French clock I was working on is sitting on a mantle that isn't at all level and it needs to be turned sideways to work properly. If its nice and straight on the shelf it is noticeably out of level and refused to work for more than an hour.

Self-beat pendulum clocks. Regarding how can you tell I put it down to experience. The feel of the crutch on the pallet shaft and the fitting. If it is a screw on fit it is more than likely self-beat. That is with most French clocks. Not so much with German clocks. The really old antique English clocks almost never unless it is by a renowned maker or inventor. American not very often. Modern clocks, the makers come up with so many different ways of design it is potluck.

Every time I work on a new clock I feel a bit like I did when Bill, the master tech I apprenticed with, sent me out to do a job. It was always a bit of an adventure and I was always a bit nervous even though he always told me he wouldn't have me do a job that he didn't think I could do.

Thank you. You’re a wealth of information. 

If you ever need to know how to regulate a Steinway ask away...LOL Steinway repetition springs are a bit of bother and you need special tools for setting let off which, of course, cost more money, etc...

I’ll see which of the books you suggest I buy is listed on the internet and go from there.

Thanks again.

Thanks for the link Oldhippy.

It dates a French Clock movement I have stashed away for a future project to between 1850 and 1880

I just finished working on a Sessions clock made in Connecticut. It has quite thin brass plates with no oil wells but I have it working again and it chimes the hour and sings the half hour. It also keeps pretty good time.

Nice to know you have plenty of work.

Yeah, mostly because no one else does this kind of thing. Every clock is a new learning experience and I only work on clocks that don’t work so I can’t make them worse...

Who knows. That 3 month waiting time might happen here. I get a lot of calls but I only work on one at a time and sometimes I like to have the clock working for a week before I get it back to the customer. 

I have a mantle clock that strikes the hour correctly for 3 or 4 days and then starts acting up and striking up to 30 times. Any ideas?

Posted

I would check the warning and if works by pins make sure they are secure. If it is behaving like it after the warning then the strike could be out and causing it not to stop the strike. Is it German, French, American or English? A photo would be nice. At the moment it is a shot in the dark.

I got the book by Conover on French Pendulum Clocks today in the mail. Fabulous book! Thank you for suggesting it.

BTW, I seem to have done something to get the hour striking mechanism to work on my Ingraham; no idea what.

Happy Christmas

    • If at all possible, find a service guide for the automatic movements your work on, because the lubrication procedures may have different requirements or rely on oils you would not use in a manual wind train (in addition to the braking grease you mentioned). Some autos like older Seikos do not have a manual wind option, so the procedure of letting down the mainspring without being able to use the crown may require a screwdriver in the ratchet wheel screw and great care. Do you have an auto movement you were planning to start with?
    • I am an amateur, so there's that. I do not get fixated on amplitude, lift angles, and beat error. However, 4.8ms would bug me if it were my watch. But you must judge your own skills to appreciate the possibility of going backward. I suggest, that you button it up let your friend enjoy the watch for now. As your skills progress, come back to it and correct it. I assume that this watch has a fixed hairspring pin. Some modern watches have an adjustable pin along with adjustable regulator. These are trivial to get in beat. I own a valjoux 726 my dad gave me on my 18th birthday (a looooong time ago). I broke the ratchet wheel with an aggressive wind 4 yrs ago. I have been waiting for my skills to progress before doing a service. I am close. Your advice is well placed and I will apply it.
    • I didn’t find any anomaly to the left of the red mark…reflection? this is the balance in its pivot in the inverted assembly. i can’t see any obvious kinks  and the spring is flat as far as I can see. Either the stud screw is missing, or it’s glued in… I don’t know. I’m loathe to fiddle with it. Any further insights? Thanks!
    • Update!  I've dismantled it, cleaned all the glue off, and rebuilt and lubricated the base movement. I'll leave the chrono part for another day. It's running well - great amplitude and keeping time, but it's got a beat error of 4.8ms.    How important is it to correct this? I'm worried that the potential for making things worse having to take the hairspring off and on repeatedly to adjust this. Would anyone here accept it at that?
