I would really enjoy watching you tackle separating the gears process, as with the Strike Mainwheel gear, so I know what to buy. I attempted to remove that exact small gear with no luck.

[@dperry428]

I assume you mean the small gear that moves the count wheel. You have to look very closely at it. I've found some that are a friction fit, but most have had a very small wire through a hole through the gear and through the arbor that holds it firm. If you assume it is a friction fit, you'll have no luck removing it without causing significant damage. Look carefully.

[@8953147]

@@dperry428 basically what type of puller would you use to remove such a small gear? I understand some damage will occur. I have a puller from Timesavers, #23770 but just too thick.

[@dperry428]

If you've removed the pin, use two screwdriver blades on both sides of the arbor underneath the gear and twist them in opposite directions. Or, use levers such as these www.ronellclock.com/product/large-lever-style-clock-hand-remover/ Hardware stores often have something similar for removing paint can lids.

If you don't have the weights, how do you know how much weight to put on a cuckoo clock?

[@dperry428]

When I've run into that situation, I attach a ziploc bag to the chain and add weights in the form of sand, pebbles or nuts and bolts until the clock runs reliably. Then, use a kitchen scale to weigh the bag. Weights of that amount or slightly greater can then be purchased from a clock supply. I buy weights from Frankenmuth Clocks frankenmuthclock.com/collections/parts-cuckoo-clock-quartz-cuckoo-miniature/weights

[@mustangk62]

LOVE this video for so many reasons. Excellent instruction! The intermediate wheel appears at 2:26:06 with no re-assembly commentary. What prevent the gear from spinning on the shaft (my current issue, hands don't move) The pin will keep the gears on the front face aligned, but something must hold the gear...spline?...keyway?...epoxy?😆 Do the washer and tension washer mentioned at 2:40 provide enough force to keep it in place? Thanks in advance.

[@dperry428]

On every clock, the motion works (the gears that run the minute and hour hands) have to have some type of clutch mechanism that allows the hands to be set to the correct time. The clutch creates enough tightness to allow the time set of gears to move the motion works, but allows enough "slip' to allow the gears that run the hands to move when setting the time. If there were no slip, the hands could not be set to the correct time. Most often, the clutch is a tension washer under the intermediate wheel. There are other clutch designs on other clocks. In this clock mechanism, the intermediate wheel is on the same arbor as the main wheel of the time train. Were it solidly attached as the main wheel is, the hands could not be moved as their gears would be locked into the time train. The intermediate wheel is loose on the arbor, but a washer with a square hole in it fits onto a square portion of the arbor and presses against the intermediate wheel with just enough force to allow transmission of power from the time train to the motion works. When the hands are moved, the legs of the tension washer slide on the rim of the intermediate wheel, allowing it to move. Here is the assembly of the washer and intermediate wheel from another video. kzbin.info/www/bejne/kJaxYWqJjJt3mpo

[@tomthomas9051]

Question regarding broaching on the escape gear new bush. Should broaching the replacement bushing (at about 1:33) be done only from the gear side? The way the broach moved suggests it could be done from either side.

[@dperry428]

Since broaches, both cutting and smoothing, are tapered, it is recommended that the holes be cut and polished from both sides to make the sides of the hole as close to parallel as possible. In the instance you reference, I was showing only the smoothing broach being used. When using a cutting broach, it is held perpendicular to the plate. With the smoothing broach, which doesn't cut, but burnishes, it is recommended that the broach be moved in a circular motion while spinning it within the hole. It, likewise, should be done from both sides of the hole since the broach is tapered. That ensures polishing the entire hole.

[@tarkushead]

Thank you for being so willing to share your repair process. One question regarding the loop on that warning lever - the loop was extending too far out. 2:11:34 What did you do to shorten it so that it rode on top of the previous wheels’ pinion?

[@dperry428]

I removed that lever from the arbor by grinding off the peened end of it and driving it out. I then measured, cut it off to proper length, reinserted it in the arbor and silver soldered it in place.

[@ozmadman]

what stops the trundles from coming out as they seemed to push in very easy?

[@dperry428]

As I show in the video, I use a carbide scribing pen to push a tiny bit of brass over each hole to lock in each trundle. I also add a small bit of Loctite to secure them. Watch starting here: kzbin.info/www/bejne/pIGmiWyZZ5WsbKc

[@robertm.6285]

For the pins to rotate, would that technically cause slipping during operation?

[@dperry428]

No. Those who believe the trundles should rotate think that it would prevent or slow wear. Others believe the only reason they tend to be loose is to ease assembly at the factory. I'm of the second opinion.

Great video! I watched one of your Faux stone videos long back and thoroughly enjoyed it! You have a calming effect as you speak, a plus many cannot claim. I was pleased when I found this video you made. As a Black Forest clock collector I have been repairing movements for some time now yet even I learned a few tricks from you, so thanks for that. My question is, aside from the need to replace a tooth on the ratchet wheel, why not just re-bush the arbor hole on the wheel using brass pipe? I have successful brought them back to tolerance using that method saving a lot of time and work. Just wanted your thoughts on that. The Philipp Hass and sons firm made quality movements in their day, recognizable by the springing rabbit verge plates, well worth all the time you spent repairing it. Cheers, Jim

[@dperry428]

I'm not sure I'm following what you are suggesting. If you are talking about the chain wheel with the hex brass, I could also just turn a brass insert on my lathe. By rebuilding with a new piece of hex brass and drilling the hole on my lathe, I know the center is true. If one puts the whole chain assembly in the lathe, there is not likely to be concentricity between the parts and the new hole drilled through the old hex would stand a good chance of not being dead center, which creates the potential for future problems as that off-center hole wears. Also, by disassembling the chain-carrying parts, I can clean each piece, which is not possible leaving it intact.

[@TheBlackForestClockShop]

@@dperry428 Hi and thanks so much for your response, I'll try to clarify my explanation, agreed, you have to disassemble the entire wheel to clean each individual component or in order to repair worn/broken teeth. In the absence of any worn or damaged teeth it is so labor intensive and requires a lathe to disassemble the chain wheel. The method I've used is to use a hollow brass pipe of which the inner diameter is the same or smaller than the arbor and the outside diameter of the brass pipe is slightly larger than the old worn hole, hence creating a long bushing if you will. I leave it slightly longer in length than the width of the wheel so it can be hammered and compressed in place and finally broaching it to match the correct hole size for the arbor. Drilling out the old worn hole centered, I use the same method as with any new bushing. Most I've attempted were pretty evenly worn holes. The chain wheel (I referred to as the ratchet wheel previously) is only serving as a pulley basically, so exact concentricity isn't so important but the few I have done worked out fine. My thought is to offer an alternative method, only if the need to take apart the whole assembly isn't necessary. Believe me, if I took apart every chain wheel I serviced, I'd have given up the hobby by now! Kind regards and I hope this explanation was a better one.. clearly your skills surpass mine in machining! Looking forward to more videos from you if you do. Jim

[@johnshand8673]

when you add wire to make a new pivot, is it as strong as the original pivot?

[@dperry428]

Stronger, actually, since I use hardened steel wire. The original pivots will bend; the replacements will not.

[@seanmooney3907]

Fantastic job! I have learned a lot from this video. Two questions I have are: Where did you acquire those cutters for the pinion wire? and secondly: What is the number of the Loctite you used? Thanks for sharing your years of expertise with us. All the best, Sean

[@dperry428]

The cutters are Xuron hard wire cutters. Can be purchased through Xuron Corporation or Amazon. Loctite is Red Loctite 262, high strength but low temperature so it can be removed with 300 degree heat. Also, chemical resistant to withstand clock cleaning solutions.

Hello, Mr. Perry! I have a question about your lathe. I'm looking into buying a Sherline 8 inch lathe for clockmaking, but I would like to save a few bucks. Would you say that the speed control is necessary for a clockmaker's lathe, or should I save a hundred dollars and forego the speed control?

[@dperry428]

As far as I know, the lathe is not sold minus just the speed control. The option is to buy the lathe without a motor/speed control. If you go that option, you'll still have to have your own motor. And, yes, speed control is essential for differing functions. Cutting brass requires a higher speed than steel, for example. Drilling to replace a pivot requires a lower speed, while polishing a pivot requires a high speed.

[@hlphipps6477]

Incredible, like all your videos. How does that hard steel wear more than the brass working against it? I'm sure there's an explanation and I'd sure like to hear it. I read somewhere in another comment you had background in chemistry.

[@dperry428]

There are a lot of variables involved in the wear of pivots and pivot holes, but one thing that can be taken into consideration is the softness of brass allows the hard contaminant particles to become embedded in the brass and grind against the steel. The differences in brass and steel hardness from one manufacturer to another is another factor. Bushings in pivot holes can be changed over time without the steel pivots being properly polished, so the steel gets progressively more worn over time while the holes are refreshed. Variables in maintenance make an enormous difference. Oil that is simply added just makes a grinding paste and enhances wear.

[@hlphipps6477]

Thank you mr. Perry for your reply. That makes sense and I guess would even apply to for example, that escape wheel wearing that steel anchor.

[@dperry428]

Yes, indeed. Also, you have say, 15 teeth on an escape wheel, each of which is scraping on the same steel surface area. Same with brass gear wheels with, for example 70 brass teeth, rubbing against 7 trundles in a lantern pinion. Each trundle gets rubbed 10 times for each gear tooth being rubbed once.

[@dperry428]

David, I can't refer back to the clock as it's back with its owner. These clocks used weights between 700 and 1000 grams. The best way to determine what weight to get for your particular clock is to hang a small container (pail or plastic bag from the chain and add weight to it in the form of sand, pebbles or nuts and bolts until the clock runs reliably. Then, weigh container with a postage scale and buy weights of equal or greater weight. As far as the length of the pendulum, the wire leader should extend to the bottom edge of the movement and the pendulum itself would likely be about 7 or 8 inches (17.5 to 20.5 cm.).

At some point, I will have to get another camera that can be mounted under the shelves above my work area. At 80 years old, I don't know how much I want to spend in time and money to do that. Thanks for the comments.

I hope to be 80 and as enthusiastic about sharing as you good sir!

Stay enthusiastic, but don't hope to be 80. It ain't fun. They say these are the "golden years". I say, "golden years my backside".

I think I saw on this video that when you re bushed you used a BB13 which has a height of 1.5MM where the plate is probably 2.0 MM. Just curious why you would not use a bushing the same size as the plate. Maybe the height is not critical? So if the height of the bushing is the same length as the pivot that is all that matters? So sorry you will not be doing any videos for a while. Sure hope you can get that hip fixed. Good luck.

[@dperry428]

Ideally, you're right that the bushing should be the same height as the plate thickness. I don't keep an inventory of bushings for various plate thicknesses, as most of the clocks I fix have plates that are 1.5 mm or thinner. In most case where I have a clock with thicker plates, the pivot holes, other than the second wheel are generally not worn, so I seldom use a commercial bushing that is thicker. Hard to justify keeping an inventory of seldom used bushings. It's easier to simply make one on the lathe with brass rod. In this instance and many others of this type movement, for whatever reason, the pivots were made shorter than the plate thickness. That causes an unusual wear problem. Instead of the pivot hole wearing through the whole thickness, the outermost part of the hole stays round and the pivot wears down the inner part of the hole until the end of the pivot is actually in a groove. I refer to that as tunneling. As it wears, end shake is eliminated and friction stops the clock. This stoppage can occur sooner than that caused by normal pivot hole wear. It also causes the pivot itself to wear unevenly. As the end shake reduces, the outer portion of the pivot increasingly carries more of the load and the pivot wears into a cone shape. So, in these cases, I prefer the bushing be no thicker than the pivot is long so that wear is even and does not create "tunneling" wear and abnormal pivot wear.

Are the wire shears you use in this video a Xuron 2193F Hard Wire Cutter? xuron.com/index.php/main/industrial_products/11/18 Thanks for the seriously impressive video. You show why a clock repair person needs to be a bit of a machinist as well. Congratulations on a very instructive video and a job well done!

[@dperry428]

I don't know if that's the exact model number, but that looks like the cutter I use. Thanks for the comments. You never know what problems you'll run into with some of these older movements. It's unbelievable what people have done to these old movements through the years.

I would like to try replacing bellows with leather. Where do you get your leather and what thickness? Bob

I found mine on ebay. Search for thin leather 1 oz or less. You can also buy it from Timesavers. timesavers.com/i-8946487-leather-bellow-material.html

dperry428, but you'll not find much. I rarely comment. I love using it as a resource but, unfortunately, there are some enormous egos and some who are easily butt-hurt and I'm just too old to get into argumentative situations. Mama told me to never get in a pissing contest with a skunk.

dperry428 im trying to specialize in cuckoo repair. It’s my main interest since I was a kid. I’d love to swap emails with you to know what Hand tools I should buy to be able to rebush. I took apart several movements this week, cleaned them and was able to put them back together successfully from your videos. Nobody around here seems to want to help out with apprenticeship etc. so I’m on my own. I read balcomb and Koch. I would love to know what I need to start out. From all I read it is broaches, some 1.4mm bushing Hand tools. Is there a way I could contact you off KZbin?

[@dperry428]

It's irritating that KZbin did away with personal messaging. Just leave a comment with your email address. I hold all comments for review, so no one will see it but me. Then, I'll contact you and delete your comment.

[@franciscole3039]

dperry428 I have this weird thing going on. West German cuckoo. It runs amazing. +1 second an hour. Everything is good. Every once in a while, random. It will cuckoo 2x on the 1/2 hour. So naturally with my ocd I twill manually go around the clock. It strikes fine and then it may strike 7 at 9pm 9 at 10. But if you continue to manually rotate the minute hand, it seems it will go fine. Happened today. After this happened, I actually manual rotated for 48 hours and it totally corrected itself. Can a cuckoo strike incorrectly if you manually move the hand past the strike time? I just don’t understand it.

[@dperry428]

Look to the front of the movement at the levers and rack-and-snail. Are all levers free to drop properly in the strike sequence? On the hour, is the rack tail falling in the center of a step on the snail? Is the warning pin on the warning wheel bent? Check the position of the gathering pallet and the warning pin at stop position. When the pin is against the stop detente, is the pin that rides the gathering pallet exactly in the slot of the gathering pallet? Something is either sticking and not dropping properly and freely or something is out of adjustment.

[@Donnybrook10]

So you live in Illinois...have you ever met Lyle Peterson aka MrPete? aka Tubalcaine? You guys live pretty close to each other and would def hit it off

[@dperry428]

No, never met him, but I've watched a number of his videos and commented back and forth a few times. I think we'd hit it off, too. He's a retired industrial arts teacher and I'm a retired science teacher. I'm in Genoa, Illinois and, if I remember correctly, he's in Batavia or the area.

[@Donnybrook10]

no way were those trundles originally designed to rotate. Imagine the extra work involved. Plus, if they were intended to rotate, the service instructions would have required they be cleaned and oiled. Further, there's no way you could keep dirt and oil out of the holes. You would see dramatic wear at the points the trundles are seated int their holes..and the brass holes would keep getting larger and larger until the trundles fell out. And that would happen much faster than the steel trundles wear out. The very theory is preposterous

[@dperry428]

I agree. I believe they are relatively loose in the holes as a convenience in manufacturing. A machine could just drop them into the shroud holes instead of having to press them in. However, if you go to the NAWCC forum, there can be some spicy arguments between the two sides of the argument. Lots of information concerning clocks creates divisive and sometimes hostile arguments.
