starting a new thread as i dont want this to take over the 'last thing you fixed' thread, and its starting to look a little more complicated now.....

i can put pics up here if needed, but basically theyre all on page 2 of that thread here.

to cut a longish story shorter, im trying to resurrect my mum and dads old wall clock before admitting defeat and binning it. it probably only needed to be balanced right, nowt wrong with it but i didnt know that, thought it needed attention so have been tinkering 😀

with some good advice on that thread, ive had the face off the clock a few times, unwound the spring by prising pawls away, put it back together, dropped cogs, put em back in (i think) the right place, mounted it on the wall again and was at the point where i thought it was working fine, just out of sync with the chimes. i was going to address that today.

however, last night it just stopped ticking and the pendulum slowed to a halt. it now wont go.
the strange thing is, it had been going for 8 hours fine, the calming sound of the tick tock in the background, so i noticed it straight away when the sound stopped.

i wound it up again but no good still. and if i start the pendulum swinging again there is just no tick tock like there was before, so this is a different problem now.

any idea why the pendulum wont tick any more? it feels more serious/technical this time. is it finally time to admit defeat? 😀

thanks

It will likely be dried out dirty and a bit tired, assume it’s not run for ages? If you can wind it fully, it ticks in beat but just stops after a few hours that’s the likely cause.

Have you committed the usual sin of covering the inside in Wd-40?!

any idea how i can get it going again tho nick?

and no, i havent used anything inside it for lube, id only use proper stuff if i did.

weirdly enough its just made a bit of a noise within the internals, sort of as if its registering hitting a quarter past or somethings, even tho nowts moving. strange....

haunted? exorcist required? 😀

Glad to see you're still persevering with this!
I have no more suggestions to make though.

I'm out with this also, other than to caution that my folks have thrown many hundreds at their clock over the years, and it's only right twice a day!
If you run out of patience, rather than bin it, try to shift it at a local auction. There's one near me that has clocks from time to time and they usually make fairly good money from enthusiastic amateurs hoping to emulate 'Repair Shop Steve'. The Mrs will then be laughing with you rather than at you...

Not really a lot you can do if you’ve done some googling and been through the basics. If it’s winding you’ve got power, but dirt, wear etc will overcome that and the movement will clog up. Can you move the hands forward normally and where has it stopped? If the hands stick then it could be seized on the strike.

Edit: just looked at your link. If you’ve wound the clock to it’s stops both sides Gently unhook the pendulum from the suspension spring and see if it starts to go.

well im still hanging in there..... 😀

tried taking the pendulum off ^^^ didnt start.

back it came off the wall but i didnt take it to bits, just looked at the rear to see what happened when i moved the pendulum hanger by hand. i could see the issue, the little spikey cog that should move tooth by tooth with each swing was just going forwards a little bit then recoiling back, rather than moving on. i didnt really do much other than keep spinning it by hand. this seemed to free it, back on the wall, didnt work. grrrr.....

one more chance you 'kin clock!

back off the wall, repeated the above, back on the wall, ooooh it seems to work now. kept trying to die again so bit of tapping from side to side to hopefully put it in balance, it kept going.

so..... im back in the game. next move was to wait for the bongs for whatever time it thinks it is. looked like i was an hour out so ive moved the hands to the correct time, stopped the pendulum, set an alarm on my phone and will restart the swing at 2pm. then that may be it!!

i think the fact that i just had to spin that cog by hand may imply that you were right that it may be age/dirt/wear that stopped it from freely moving, lets hope ive freed it enough to keep going a while longer.

thanks for your help. ill update on whether its still alive after a few days of constant tick-tocking 😀

cheers

its slowly slipping away from me 😀

got up this morning and noticed it had stopped. bahhhh.....
however, one strange (or not) thing i noticed is that it had stopped at the same time as the last time, 7 minutes past 11.
so......using my superpowers of deduction i twig that the little cog that was stalling with the swing of the pendulum, and that i pushed round manually to get going again, probably isnt the culprit.
its this cog at the top right, the one in focus.

now if that moves one tooth every tick, then it must rotate many times a day and wouldnt cause it to only stop 12 hours later.
so, super powers again, the culprit must be the cog that takes exactly 12 hours to rotate, and thus must be tied to the centre spindle for the little hand to do one complete rotation. this centre cog....

[img] [/img]

a bit of playing about trying to move it by hand (which i cant) means i cant see any way of 'freeing' or 'loosening' it any, so although ive got it going again, itll probs stop again at the same time tonight. and thatll probably mean end of the game for me.

just one question that intrigues me tho. this is the back of the clock....

[img] [/img]

the cog at top moves on pendulum swing, that rotates the one to the left, which over 12 hours rotates the middle one.
what are all the others for? i cant see why theyd be needed if those other 3 cogs deal with 12 hrs worth of time. theres loads of other little cogs in there, and those 3 big ones at the bottom?

anyways, its been interesting, wifes praying i cant fix it cos she doesnt like it, and she'll probs get her own way now. shame 😀
