• Upcoming updates
    Over the next couple of weeks we will be performing software updates on the forum. These will be completed in small steps as we upgrade individual software addons. You might occasionally see a maintenance message that will last a few minutes at most.

    If we anticipate an update will take more than a few minutes, we'll put up a notice with estimated time.

    Thank you!

    Lorenz Furtwangler Sohne: Escapement? Opinion Needed!

    Yes, I would think if the beat were erratic, I would look at the verge bushings and well as the escapement wheel. This clock I can get in beat to 0-1% and it stays firmly in beat from then on. There is a blob of solder on the verge - and not sure why. The anchor is firm on that arbor...

    Lorenz Furtwangler Sohne: Escapement? Opinion Needed!

    I agree with DF. I tried it and it worked, but I was skeptical, because sometimes even with the lighter weight the are periods of no go, and go. I think it may be borderline or there is something intermittent based on position of something or both. I took off the pendulum to adjust the length...

    Lorenz Furtwangler Sohne: Escapement? Opinion Needed!

    "Well, there are two weights that seem to be original - just like the rest of the clock. One is about 7 pounds, the other about 12 pounds. For giggles, I just switched the 12 pound from the strike to the time. Let's see how this combination works." Interestingly enough the clock has been...

    Lorenz Furtwangler Sohne: Escapement? Opinion Needed!

    Sigh. There are only 4 wheels in the time train from power wheel to escape wheel. They spin so smoothly unloaded! Now with new bushings in there, I would think that when loaded it should be smooth as well. The lifting lever does not add much resistance - and the clock never stops during the...

    Lorenz Furtwangler Sohne: Escapement? Opinion Needed!

    A photo of the pallets is below. The pallets are tight - no slop or movement - the screws are holding them well and no buggered up. The pallet surfaces do not show any wear at all. The arbor has normal play (end shake). There have been times when the clock will run for days. Then I think all...

    Lorenz Furtwangler Sohne: Escapement? Opinion Needed!

    The overall pendulum weighs 6.8 pounds; it is about 115cm from end to end; and the heavy bob is about 22cm in diameter. It seems to be original to the clock.

    Here is another video with more illumination and hopefully better focus.

    Lorenz Furtwangler Sohne: Escapement? Opinion Needed!

    Thanks Bruce. The suspension spring is new. The broken one had a thick metal housing to fit in the slit. I found a similar sized spring (but not exact) in my drawer. The housing was not as thick as that old one that broke, so I put some filler metal around it to give it a snug fit in the...

    Lorenz Furtwangler Sohne: Escapement? Opinion Needed!

    I have a tall-case clock was made by Lorenz Furtwängler Söhne, in Furtwangen, Germany in the Late 1920s. I cannot keep it running. The movement was cleaned part by part and freshly lubricated. The bushings were not bad, just some slight wear. However, I could not keep it running for more...

    Grandfather Clock Esapement Issues

    That is an "old" grandfather clock! Perhaps English from the mid 1800s. Try remove the second hand and seeing if the problem still happens. If it doesn't, then it is your second hand touching something when rotating.

    Music weight does not lasts 8 days?

    Yep, not normal. Music only on the hour and the tune will alternate each hour.

    Bushing replacement query

    An option is to put a smaller outer diameter KWM inside the currently installed Bergen. Sometimes the current bushing pops out doing this procedure. Just wondering the better path that others prefer.

    Bushing replacement query

    I use KWM as well, but I have Bergeon bushings. If a previously bushed plate was done with Bergeon bushings and they are worn, is it best to pop them out and replace with new Bergeon bushings? Would they have a loose fit??

    Like a Bicycle Chain

    It sounds like loss of power due to a worn pivot is more at the pivot-bushing interface that at the teeth-pinion interface. I wonder if there have been tests/demonstrations to prove/show that assertion. A couple of bushings installed in 10 minutes? When using a mill the accuracy is very high...

    Like a Bicycle Chain

    Is "tunneling" the same term as "wedging"? I think I heard that term used before. Is it known or believed that wedging causing more loss-of-power than the angled messing of the teeth?

    Like a Bicycle Chain

    I thought that if the clock was working before cleaning, then it should work after cleaning - but better. It may not always be the case (assuming no errors or bent pivots). In the past I thought that lost power due to an elongated bushing was due to the gear/wheel teeth being out of alignment...

    Like a Bicycle Chain

    I have experienced bicycle chains with layers of dirt and oil - and the chain does work. However, once you remove the years of grime, the chain will no longer work as the links have lengthened and the chain ring teeth have worn. Thus, grime was filling in the gaps somewhat. Is it the same for...

    1920s German Tall Case Questions

    Thanks Willie for that bit of information. Nevertheless, I cannot keep this pendulum going. The pendulum is very heavy - which is interesting, but makes for the hanging of it a little more tricky. The strike weight is about 12 pounds and the time weight is about 7 pounds. They seem like the...

    1920s German Tall Case Questions

    Continue with my questions on this clock. I cannot keep the time train going. A few of the bushings are slightly worn, but not so much to warrant new bushings - especially with the over 7 pound weight. The time stops at random - so no hands hitting each other or the classic 3 minutes to the...

    Understood. It entered my brain with "while winding". Thanks!
