    I found a small, $8 clock in a broken up celluloid case hidden away in an antique mall...

    ...that I am considering cleaning and putting into a piece of wood I have for an office desk clock.

    upload_2018-1-14_16-50-47.png

    It has a broken spring but also needs a good cleaning. I have disassembled it almost all the way down but I cannot see how the main hand gear comes off of the face back...

    If anyone can point me in the right direction it would be greatly appreciated...

    Also. it looks like it is missing something that would screw onto the winding arbor. If anyone has an idea of how to replace or jury-rig something for winding, that will also need to be addressed.

    I posted about this clock in the "New Acquisitions" thread as well and JTD thought it might be a german movement, possibly from the '30s. If any one has any other thoughts...

    If you can ascertain the threads on the winding arbor let us know and there may be some suitable winding keys in someone's bone yard.

    The small gear on the front is pressed onto its shaft and can be removed by pressing it back out, but don't do it: it's almost always unnecessary and there's a chance of damaging the clock.

    The last adventure I had with anything like your missing winding arbor involved the setting knob on an electric clock. It had a left-handed thread and I was out of ideas until I found a large-diameter brass bushing with a 2mm hole through the middle. I broached out the hole a bit at a time with a tapered cutting broach until the bushing would start to jam onto the threaded-steel shaft. After annealing the brass bushing I was able to use the shaft as a sort of tap, stopping my efforts when the bushing seemed secure. I was then able to solder sort of crossbar onto the bushing, and now you can set the clock.

    It's a shame about that case. I rather like it and wonder if it can be restored.

    Those kinds of clocks often wind CCW, and the teeth are left threaded. A proper key will turn onto the threads CCW, tighten and enable the clock to be wound.

    First, thank you all for your assistance...

    This is a blow up of one of the shots I took while disassembling the clock... I do not know if you can tell from this photo, I will need to go have another look but it does appear to be CCW as others have indicated...

    upload_2018-1-17_9-11-55.png

    ...If anyone knows where I can get one that would work, that would be great. If they are standard and I just need to find another old, cheap wind-up clock, I will start looking.

    Timesavers sell a mixed assortment of suitable keys (#10600). One of them should fit your clock.

    Sorry, I should have made clear that is the Timesavers catalog number. If you go to their website and put 10600 in the search box you can see the item.

    Uhralt already gave him one in post #9, which was why I didn't.

    Sweet! May not seem like much but got it all reassembled and it seems to be ticking along...(pardon the pun)...

    Still need to get an actual key as I wound it with pliers...

    Yes, get a key. You'll mar up the winding square with pliers, and will have to do more work to get it right again.

    Just an FYI... I did purchase the set of 72 keys as recommended above and was a bit disappointed. I thought that in that many, there would be one that fit. However they are all basically the exact same winder key with the exact same thread size (too big for my clock). The only difference in the 72 keys was the handle configuration of which there were 6 different styles.

    I had the same problem with the assortment from Timesavers. Mine was a left hand thread, and some odd number for the thread count, but surprisingly I found a place that sold the tap. Got some tiny brass pipe and tapped it. Made a slot in the top and crimped in a tab. A lot of effort, but it did work. Later, I found it easier with the little New Havens to just look for a donor movement that had its key.

    So I bought "c-31" clock winder for this clock from ebay for just a few bucks and it appears to be the correct size but is is a right-hand thread.

    Does anyone know where I can get a left-threaded winder of this size? The clock is otherwise operational now and I would like to finish it up...

    Thanks!

    If you look at the early posts you will see very well what clock he is talking about. He has posted photos.

    oops… I was on a mobile device and thought that was the first post!

    Still don’t know what that Winder is, though… Assuming it’s some kind of electric thing?

    No it's nothing electric. If you read post #18 (and earlier) you will see that he is talking about a key to wind up his clock.The one he bought was the right size but he needs one with a left handed thread.

    Clear now?

    JTD

    And now I see that two other people have explained it for you.

    no need for snark... this is a nomenclature issue. he's not looking for a standard winding key. he's looking for more of a threaded winding knob that threads on the winding arbor as with travel/alarm clocks. the 'knob' might look like a key, don't know... but it ain't a standard 'winding key'... which is the term that was used in a bunch of posts here.

    what is being discussed is a 'left-threaded knob female'... and a simple google search will offer up at least some places worth researching.

    or, you could try to find the right tap and make your own.
