General clock related question.

Recommended Posts

Clock guys,

I've not worked on clocks and though I understand the principles I'm after some general info please.

A friends Mum has a lovely wall clock with pendulum and 3 spring barrels (chime and half hourly) which slows and eventually stops within about 2 minutes of being started by hand.

The pendulum appears to be tilting back slightly. I.e. clock case leaning backwards. I've adjusted this a little but it's still not perfectly hanging down. It's not catching anywhere and the movement from a cursory inspection appear very clean.

The biggest problem is, despite my working on watches she's very reluctant for it to be touched because a work colleague of her husband's years ago did some 'fix' on it which apparently involved using a nail as an impromptu staking tool and a few years ago it was taken to a proper workshop, was working nicely when collected but soon as it was re hung stopped doing so again.

Aside from the obvious mainspring, train wheels lubrication etc is there anything that could cause it to slow and stop when it was apparently working on collection?

Is it in beat?

Is it making a nice Tick, Tock sound, or does it sound like an old man walking on crutches?

If its not in beat it won't run well, or if badly out of beat not at all.

An easy test is to tilt the whole case on the wall left or right a few degrees and see if the ticking sounds better or not.

If it does then its out of beat and needs to be adjusted which is not hard, just Google 'Putting Clock in Beat'

If it was working, got taken home and then stopped working being out of beat is very likely.

Hi  As Tmuir has already explained listen to the tick tock    Have you any pics of the clock and movement for reference.    I as a geriatric use a beat amplifier to listen to the clock, But there is an app FOR THE IPHONE  called clockmaster wihich i also use for calibration and setting up, I just requires the pickup or mich putting close to the clock and setting the app running.

Useful stuff, thanks, I'll take a look when I get the chance. Being a pendulum clock won't tipping it affect the operation of the pallet though.

When I next look I'll try to get some snaps to upload.

Its good practice to have a spirit level with you, moving any clock from A to B can upset the clock, particularly with wall clocks, the walls are normally un-even in old type homes. Make sure the pendulum is free from any obstruction, it should be in the middle of the crutch, and the suspension spring should be free to hang down, not stiff or pointing at an odd direction. The springs have some power on, Many wall clocks need to be secured to the wall.

Thanks, one thing we know for a cert is that the walls are uneven. Don't think I've ever lived in a house in the UK with straight and level anything. In fact my last house had a level driveway but I only know that as I saw it laid and smoothed. 

The biggest obstacle is it's a friends Mum and she doesn't like it being messed with because of the previous problems, I'd love to whip it off the wall and have a good forage into it but she'd probably have a heart attack. 

I'll try to get some pics and see if I can see anything.

This movement has a friction tight crutch with an attached scale for the pendulum to show it is dead center. The clock should have a nice even tic tok. There is nothing in the way that can interrupt the pendulum that I can see, the suspension spring looks right. The escape wheel and pallets look dry so a little oiling will help a lot, that could be the reason why it is temperamental.

Hi    Without getting your hands on it will be a problem But as OH says a bit of oil might help the problem.  Along with the clockmaster app there are several free down loads for spirit levels which is handy as the phone will fit in the clock case bottom, these levels give reference both ways so should make an accurate set up of the clock.  To make a clock amplifier I use pizo disc with a croc clip attached and a radio shack telephone Amplifier and a bit of twin core sheilded cable. Not rocket science and very useful. If you want a picture let men know.

the repair and service is not too complicated, but my grandma let too many of the kids "work" on an 1900 mantle clock.  i would avoid the job at all cost.   vin

That'd be interesting to see if you wouldn't mind. Is clockmaster available to us android ers?

Looking, stripping, servicing etc isn't the problem, convincing my friends Mum I am capable and won't butcher her lovely clock and working on it without her hovering and asking everything I'm doing is. :D

Hi I have attached the pics of the amplifier setup  I dont know if the radioshack telephone amplifier is available in the UK any more but there must be others that will work, With the loss of Tandy and Maplins these sort of bits are hard to come by, Might get them off the net .

    • hope it helps.  As it seems you are UK based, you also might inquire about a local model engineering club.  Most of what I saw in the video was fairly generic stuff and may appeal to various hobbies centre around machining other than horology (and many model engineers also build clocks).  The UK is the centre for model engineering, you might find that including that fraternity greatly increases the target market size
    • It seems an odd choice, but it may not do harm.  imo there is no reason to use a multiweight oil,  but maybe there are good reasons I missed.  I also don't see a reason to use a synthetic oil, won't hurt, but they are more money.  Regular oils don't break down until 270F - there's some serious issues if that's a factor with a lathe .  It seems a topic full of hyperbole and little expertise; there's one horology oil report claiming synthetic oils don't contain hydrocarbons!   What nonsense..  Multiweight oil are designed for internal combustion engines where there's a big temperature swing.  The low initial viscosity helps get oil pressure built up quickly and makes cold cranking easier.  But the engine quickly gets up 220F or so and the oil operates at its high viscosity (oil viscosity is determined at a set temp, i.e. an oil of X viscosity means its X at 40C, it will have a very different viscosity at 110C).  Your lathe just doesn't go through the same temp swings, say -40 to +220 n the dead of winter so I don't see how a multigrade makes any sense....except maybe because is readily available? In general with machines, motor oil is really frowned on because of the additives and detergents.  They're are needed do deal with combustion, but not wanted in a gearbox/bearing bath.  Watchmakers lathes are a total loss system so these objections I don't think matter much, but its worth mentioning in the context of machine tools and oils. With a 0W20 run a low temps, you're really only going to see the "0".   The zero isn't really zero, its just small, maybe the equivalent to ISO 3 or maybe 4. ( 0 Viscosity is superfluidity, liquid helium laboratory stuff).  So what really matters?  That its a clean mineral oil (i.e. hydraulic oil) and of the right viscosity (singular) So that's the real concern I had, Is ISO 3 or 4 enough?   I'd have guessed no, but maybe.   Most of these lathes don't come with a viscosity recommendation.  Clock oils often recommended are afaik much higher than 3-4 but (snake?) oil marketing, while full of lofty claims, rarely even states the viscosity!   .  I suppose it can be overthought, these lathes seem to easily last 100 years with whatever is put into them,.  So long as the oil is thick enough to keep the parts separate at speed, its thick enough.  Still, i think synthetic and multigrade oils in a plan bearing are, well, just not required.  
    • Thank you Mark that is very helpful.
