    Junghans "Cuckoo" Mantle Clock Dating.

    I had the exact same problem with this clock, and it drove me mad. I finally broke down and cheated. When I overhauled the movement I made sure to remove the Bird and its mounting post installed in the upper left corner of the case. Ensure that the post pivots are squeaky clean and polished...

    Junghans "Cuckoo" Mantle Clock Dating.

    I was out on LiveAuctioneers.com looking at photos of Junghans mantle clocks and saw one with a trademark similar to the Cuckoo Mantle clock with B12 stamped under the trademark. Were they using the Letter=month with 2 digits for the year of manufacture? In this case February of 1912?

    Junghans "Cuckoo" Mantle Clock Dating.

    I too have never run across a Junghans Cuckoo, in any form. I've worked on many Junghans mantle and wall clocks over the years, but never one of these. Ignoring the noise from the bellows, the hour gong IMHO is the prettiest sounding strike I've heard in a while, and surpasses the sound...

    Junghans "Cuckoo" Mantle Clock Dating.

    Just finished rebuilding a somewhat neglected Junghans "Cuckoo" Mantle clock. This is a real gem compared to the mass produced Regula and Herbert Herr cuckoo clocks that typically come through the door. Has anyone run across one of these who can put an approximate date of manufacture to it...

    Barrel Bound Mainspring?

    They certainly are! I stand by calling it a tool because they do so much more than just winding and unwinding mainsprings. Definitely on my "indispensable" tool list.

    Barrel Bound Mainspring?

    A Bergeon, Ollie Baker, Webster (my favorite), lathe, or some other tool used to help safely remove and install mainsprings.

    Help Grandfather Clock stops before hour strike but not always

    I haven't read through the entire thread yet, but I've had several "hard life" vintage tall case clocks that would also run great on the test stand, but fail when installed in the case (post overhaul, all the pivots, bushings, cams, levers, wheels, pinions are correct). Check the movement seat...

    Barrel Bound Mainspring?

    The article referred to the term as a condition to inspect the mainspring for after it was removed from the barrel. The same as you would inspect for rust, pitting, cracks, damaged "hole ends", etc., etc. If the edges of the spring were abrading against the barrel cap or great wheel, I'm not...

    Barrel Bound Mainspring?

    Technically that would work as "barrel bound" too. The article used the term as if it was part of the established horological lexicon. I'm just hoping to verify if my understanding of the term is basically correct.

    Barrel Bound Mainspring?

    I've had clocks with that issue too. I encounter it mostly with 400 Day clocks that quit if the suspension breaks or some other issue occurs after a full wind. After the event, the clock is stuffed in a box and put on a shelf to gather dust for the next 40 years or so. I always referred to...

    Barrel Bound Mainspring?

    I was reading an old article in the May, 1996 edition of the "Horological Times" discussing mainspring inspection and maintenance. In the article one of the faults listed in the mainspring inspection topic was "barrel bound". However, the author never explained what this meant. I've never...

    Mainsprings for Schatz 2-Jewel Ships Bell

    Per "Shutterbug" in a 2014 post, "I think I'd go with #16784, cut off the excess, anneal it and punch a new hole." That's what I did (available from Timesavers), which worked great. As a source for the platform escapement assembly and bell (I've never seen a gong coil on a Schatz S.B.) the...

    United Clock Company "Fireplace" Clock

    Hi Andy. Thanks for posting the photos showing the color patterns on the cylinder. I figured I'll try crumpling some tin foil, and color it with magic markers like you suggested. I'll wager if I model my color patterns after your photos, I'll have a reasonably nice simulated fireplace...

    United Clock Company "Fireplace" Clock

    Hi Andy. I had trouble too, but I was able to get everything out through the clock movement opening. The trick for me was to loosen the nut holding the small right-angle bracket to the mechanism. See my second photo at 2 o'clock from the center of the cylinder. Unbolt the bracket from the...

    United Clock Company "Fireplace" Clock

    Never mind. I found a photo of one that sold on eBay that shows the cylinder (attached). It also shows a white bulb used. The color is provided by the rotating cylinder. Regards -- Mike

    United Clock Company "Fireplace" Clock

    I'm currently working on one of these. Everything is working fine (bulb, clock, animation motion works) except for the flickering flames. The motion shaft rotates as it should when engaged from the rear mounted lever, but I'm missing the rotating disk that simulates the flickering flames. Can...

    Moebius Synthetic Clock Mainspring Grease?

    Hi Glen. Thanks for the information you provided; I'll give the Lucas 50W a trial. I don't have the MSDS for 9550, or any of the Moebius products. I need to figure out how to get a "special" customer ID from Moebius to be able to download their product MSDS sheets. You'd think they would...

    Moebius Synthetic Clock Mainspring Grease?

    Without going into my reasons, I've been slowly switching over to using only Moebius synthetic oils for clock and watch applications. The one place I haven't made the switch is clock mainspring grease. I've reviewed the Moebius technical sheets for their synthetic greases and think their 9550...

    Trend Clock Co.

    The Hermle 241-8XX movements are offered as cable driven, time & strike with a single hammer, and may very well fit the mounting rail left in this case. I think Mark can fix me up with a complete Hermle kit with pendulum, weights and dial at a price the customer can live with. Plus, if Urgos...
