Junghans?

[RogerH]

I've just bought quite a handsome wall clock.....I won't say Vienna but it's that style. The case is ok but needs a good clean up. The ceramic face is in good order and the mech, at first glance looks to be in good order. However,  when you look closer it's clearly had some work, and not that good in my opinion. It does look mechanically sound but it doesn't run for longer than a minute. I think I the main problem is the suspension spring which has clearly been "repaired" but I can't find a replacement anywhere. Am I right in assuming it's a Junghans? The symbol suggests this but any help or info will be much appreciated.

Lovely old movement otherwise.  I think Old Hippy may drop in and advise shortly.  I knew a site which had all different kinds of suspension steels and other clock stuff, but it was bookmarked on my prior computer which died (and taught me to print out my bookmark file every now and then from here on).  Got a new computer and now wracking my brain to remember all the old sites I once saved.

That's kinda like printing your map directions rather than just using any of the myriad phone apps. Better would be to use a browser like chrome with an account feature that syncs bookmarks. You can have access to your bookmarks on any machine that can run a chrome browser.

Nice clock Roger ,  Nice repair to the suspension !  Cusins uk, Meadows and Passmore, will have the bits you need for sure..     Yes its a Junghans   made in Germany, like Hermle they are nice clocks.    cheers

Not much to add apart from I bet the movement is in a case the style of a Vienna. Bad repairs all round  poor job of the suspension which clockboy has pointed you to the replacements. The hole which I have marked which is on the going side needs to be looked at. When I see a clock where the pinions look clean It always points me to the pivots and the holes and teeth. Not bad movements this one has a count wheel strike.

Thanks OH, I think it may be alright. I've given them all a clean and they seem ok. I found a sticker saying it was "serviced" in 2005.

[oldhippy]

Whoever repaired it certainly needs a few lessons in re-bushing.

[RogerH]

The sticker said The Clock Clinic Putney. I'll give it a clean and oil, fit a spring and go from there.

[RogerH]

so, I've received the suspension spring but I think I've ordered the wrong one....or am I just missing something! there should either be another part or it's just the wrong spring ?

[clockboy]

It looks a tad to wide but the length will have to be the same length as the original. If as a result the pendulum is to short or long regulation will be troublesome. I am not sure how the two (Leader & Spring) are joined together. 

[RogerH]

Thanks Clockboy. I'm not convinced by the length either but the original was clearly something bodged in. my main concern is how the two connect - can't seem to find info on it anywhere!

[RogerH]

I found this on Ebay - it suggests the two are just welded?

[oldhippy]

You normally rivet them. They used to come with the rivet it will be an oblong shape. You most certainly will need to make pendulum adjustments. Also make sure nothing is rubbing or touching around the crutch it has to be free. 

[RogerH]

Thanks OH. Cousins do this...

would that be the answer or is that for something else? and is there a correct way of determining the correct length of the pendulum assy including spring?

[oldhippy]

That's the type you need. 

You don't want the pendulum touching the bottom of the case as it will not go. When it's all together somewhere around (red mark) where the crutch needs to be. This will be a trial and error. Don't alter the pendulum yet just see how it goes. If it starts going nuts in say an hour then alter the pendulum.

Thanks Roger another piece of the huge learning curve solved.

[RogerH]

Thanks all, I'll crack on and keep you posted. Thanks for all your help so far.

[RogerH]

So, just a quick update. the joining pieces arrived and worked a treat! It still needs a bit of setting up but the mech is running very nicely. The only other issue now is the pendulum weight itself. it should be the standard R&A but it's badly worn. However, I see no need to replace the whole assy. can you get inserts or a replacement cap? I did consider rubbing it back and painting it with a brass enamel paint but any advice on what should be done will be much appreciated. I've seen a few of these now with similar wear so it must be a fairly common problem.

[oldhippy]

Two suggestions, are there transfers available, how about a signwriter, or as you say rub it down an paint it. That suspension looks fine.

You need one of these if its not the right size you can always scan, adjust and reprint:

[oldhippy]

Excellent find wis1971.

[wls1971]

I bought one because there where only two, I will scan it when I receive it and make a pdf available to anyone who wants one, resized and printed on glossy paper they should make a good substitute.

Brilliant, many thanks. That's the sort of thing I thought there would be plenty of and was surprised to see there wasn't anything about.- I've bought the last one as I have another worn one that will be part of my next project.
