Repair of Cuckoo Clock with Music Box for Kim

[@moorecomp]

I have recently begun repairing clocks and your videos have been a great help and inspiration for me. The first cuckoo clock I repaired was not an easy one as it was a Hubert Herr one day clock with a music box similar to this one. I know it is recommended to do a simpler one for your first try, but it worked out good and my wifes friend was thrilled to have it working as it belonged to her brother who passed away a couple of years ago on Christmas day. I took it to her house and set it up for her. She had never heard it before and the tears flowed when she heard it for the first time. Thanks for providing these videos so this knowledge can be passed on to others. Best regards.

There is a lot of sentimental connections with old clocks. The memories people have attached to them make it important that we can restore them to function. Thanks for the comments and I hope you get as much enjoyment out of this hobby as I've had over the last 56 years.

So glad to see you back. I was hoping there was no problem. I know it is cold there so I was hoping you would be doing some videos. Great job by the way

Just spending a lot of time with grandkids.

I was blow away when you said you did theses repairs as charity. I too love to fix clocks and pass on the enjoyment of spring and weight drive clocks. There is nothing like the sound of a good clock ticking away.

This was a very interesting video. A long time ago in one of you videos you commented that the cuckoo clock movements are so cheap that it is tempting to just replace the movement as opposed to servicing it, and that is what a lot of guys do. Mark Dalton made a video in which he replaces a cuckoo clock movement in about an hour flat, and if you are repairing clocks as a business, time is money. Dalton is very skilled, so he did a better job than whoever last worked on the clock in your video. You probably spent more time replacing the end of the cuckoo perch than Dalton did on the entire job. The technique you used of filing a flat edge on both pieces and then silver soldering (there is a name for that kind of joint and I forget what it is) I've seen before on some of James Martin's videos. You did a great job with this. The way this movement is set up, with pretty much a plain vanilla time and strike cuckoo movement with a lever that actuates the music box reminds me of the Seth Thomas Sonora clocks, with a plain vanilla Seth Thomas 89 time and strike movement that actuates a separate chiming movement. This clock plays music on the half hour and the hour; some of them play music only on the hour. I'm working on a Mauthe musical alarm clock. When the alarm clock goes off it plays a music box instead of ringing a bell. The comb on the music box is missing two teeth just like the one in your clock. I guess there isn't much you can do about it; the music boxes seem to sound OK even with a couple of teeth missing from the comb. It was great that you showed us the half hour and hour strike at the end of the video. This clock looks and sounds great. You did a very nice job with it.

Thanks for the comments. I always enjoy seeing other points of view. As for replacing movements, there are two reasons that I, personally, won't do it. I'm doing this as a hobby. I'm retired and don't want to do it as a business as I don't relish the thought of keeping books for the IRS. I don't charge for my repairs. I ask only that a donation be made, free will, to our local food pantry. I make a few bucks off the videos that Google sends a 1099 form for my taxes. Most of the people I repair for don't have the money to take a clock to a professional shop nor to pay for a replacement movement. I enjoy fixing the old movement. There would be no pleasure in just replacing one and I couldn't afford to do that for free. Secondly, many, if not most of these clocks have sentimental value to the owner. "I remember listening to this clock at grandma's house when I was a kid" is what I often hear. Is it still grandma's clock with a new movement. I'm reminded of the old man who says that he has an axe that belonged to Abraham Lincoln from 1845. The handle was replaced in 1900 and the head rusted out and was replaced in 1920, but he still claims it belonged to Lincoln. Really?

BTW, it's called a half-lap joint.

Great Job. I'm glad to see you again. I've got a Cuckoo Clock to my Birthday on Tuesday. I cleaned the Movement and now it works fine. Happy New year and God bless. Best Reguards from Germany

Thank you and Happy New Year to you as well.

What reamer tool did you use and deburr tool, I clean Regula 25 movements often but never repivot, if I see the movement needs repivoting then I don't touch it or clean in. I don't have the slightest idea on how to know if I bought the right size bushing to match the hole the reamer tool drilled before tapping the bushing into the plate, I have a pivot gauge I found in a box of clock parts. Do all of the new bushings match the size of the reamer tool no matter the size of the pivot needed?

[@dperry428]

First off, there is a difference between repivoting and bushing. A pivot is the end of the arbor that holds the wheel (gear). Repivoting is when you cut off the worn end of the arbor, drill into the end of the arbor and put in a piece of pivot wire . Bushing is when you replace the worn hole in a movement plate. To bush a worn hole, you first measure the pivot that goes in that hole. Then, you choose a bushing that has a bore (hole) of that size or smaller. That bushing will have a certain outside diameter. The reamer that is used is one that is a very tiny bit smaller than the OD of the bushing. For example, Bergeon bushings have outside diameters of 2.0 mm, 3.0 mm 3.5 mm, 4.0mm, 4.5mm. The reamers that go with those sizes are 1.97 mm, 2.97 mm, 3.47 mm, 3.97 mm, and 4.47 mm. The hole is reamed out with the proper reamer and the slightly larger bushing is forced into the hole. I use a chamfering tool to remove burrs before putting in the bushing. You could also use a drill bit larger than the reamed hole to do the same thing. The new hole is then broached with a cutting broach to make the bore (hole) an exact fit to the pivot. A smoothing broach is then used to polish the hole. The two systems used by most people are either Bergeon or KWM. Since I use the Bergeon type, I won't get into KWM. OR, if you have a lathe and brass bar stock, you can make your own bushings, drill a hole in the plate slightly smaller than the bushing you made and then broach the drilled hole with a cutting broach to a size that will make a tight fit for the bushing.

Hello i just got 5 coeko clocks 4 i got working but one the smallest and the oldest does not run but the coeko is comming out but no coekoo and it stays out ??? i need help its a little one with the red star on the front of the dail..ooh if i pull it a little it keeps going on and on ???

[@dperry428]

Far too many things that could be wrong. Take it apart and check bushings. Check for torn bellow leathers (papers). I can't diagnose problems online without examining the clock.

[@paddypup1836]

Hope you are doing well. Happy 2024.

[@dperry428]

Same to you. I'm doing pretty well. I'll be 81 next month. Can't wait for spring so I can get back outside to do my next concrete project.

Thank you. I will.

[@sarahostelka4587]

Dperry Is there any chance in the world I could send you my clock for repair? I’m so sad it does not work. Please let me know if this is a possibility. Thank you Is there a way I can give you my email without the whole world knowing? I really hope to hear from you!!

Try putting it in a comment. I hold comments for approval before posting them. I can get your email and then not post the comment. It helps to put the @ sign as a the word "at" and the period as the word "dot" or "period" or KZbin will censor it since they don't allow links to outside KZbin.
