    Clock balance and Pendulum Beat Timing

    Yes I have experienced that same thing. Every clock I use it on has sort of a sweet spot where it works best. Most of the clocks I use it on are the Self Winding (F) movement variety and the metal cased clocks are more of a challenge then the wood cases in dealing with those other background...

    Clock balance and Pendulum Beat Timing

    I’m not sure if I’m posting this in the right place but hopefully it might be of some interest and help to those looking for a cheap way to balance and time a pendulum clock. There is an app called Cuckoo Clock Calibration. It is not just for Cuckoo Clocks, but for pendulum or balance wheel...

    SWCC Type F Movement Winding Time

    That is strange. I just tore one down that had a 10 sec wind time. It had 6 prewind turns on it. I checked it out of curiosity because of all the trouble your having. If I understood you correctly, you stated you had 7 turns prewind before reducing it to 4 turns, and after doing that your wind...

    Sorry Dave, yes that was meant for you. I’m not sure what happened to the rest of the text, but checking that prewind was what I was trying to get across.

    Dave, the winding contact is fairly straight forward. If you look at the bottom of the page that talked about adjustment with a pair of tweezers, it notes (exaggerated) I was more concerned that you didn’t have enough clearance then too much. Getting back to Harry‘a comment, I think he is right...

    SWCC Type F Movement Winding Time

    By the way Harry, I do have a SWCC clock out of the case, really it’s just a spare 120 Beat movement that I have mounted to a piece of plywood (test jig) so I can work on them. Really I’m not a collector of anything but SWCC Clocks. I was always fascinated with the SWCC sync mechanism and it’s...

    SWCC Type F Movement Winding Time

    Harry, I think you are correct and I believe I’ve learned something here. Everything I’ve read backs up exactly what you’ve stated. After reading your post, I went back to check a clock that I thought I reduced the wind time on by hitting the manual wind contacts. It didn’t go back to where it...

    SWCC Type F Movement Winding Time

    If you have to remove the spring assembly, pay particular attention to the pin that goes through the shaft. It sticks out farther on one end. It’s an important step when reassembling. There’s good documentation on this. These photos are of one that has not yet been disassembled and is correct...

    SWCC Type F Movement Winding Time

    We must be missing something major here. I’ve never seen one wind that long! Makes me wonder if the contact that the cam pushes up is not releasing or needs more clearance. One thing is for sure, that contact is engaged way too long. That also brings that knock away piece back into the picture...

    SWCC Type F Movement Winding Time

    Merry Christmas to all! Well Dave I sure hope that thing stays consistent in its wind time. I’ve never seen those armature spring adjustments cause really high wind times; that’s been my experience anyway. Usually rubbing in that area can cause the little ratchet to not give the wheel the...

    Hey, don’t sweat it, we’ve all “been there done that”! Glad that’s all it was

    Here is some additional instructions for alignment if those contacts.

    By the way, in your video, that contact ‘is’ in the correct position riding above the pin. Dropping it below the pin is just so you can adjust the proper clearance, contact mating and position of platinum surfaces, and the tension at which the two mate.

    Dave, I may have misunderstood, and what you were trying to show in your photo is the clearance you adjusted the contact to. Anyway, here’s a couple of screenshots from Ken’s Clock Clinic on how to adjust those motor winding contacts. I have some other documentation on this, just have to find...
