Replacing ALL the teeth?!

In this video I show the work I did to restore a wheel in a Chronometer. The wheel had been damaged and would certainly have been a candidate for replacement, but I wanted to try and repair the damage without replacing the wheel. See how I got on and let me know what you think of the results.

Everybody has already commented upon the superlative engineering skills. Can I add my appreciation for the superb quality of the video and commentary.

[@wombleofwimbledon5442]

My boy watches Clickspring. You can just tell.

[@geraldguenard4095]

SIR. congratulation you are a real proffessional.that is a master piece. BRAVO.

[@dippydipso5355]

I am in awe at your work. Brilliant. Thank you!. For me to attempt this operation I would have use a lump hammer and a cleaver..

[@bradleyleben7785]

Super job! That lathe is special.

[@pafurnace]

I would not have thought that sort of repair was possible! My clock work, compared with yours, is blacksmithing. I have no delusions of ever gaining these kinds of skills. Even so, your work is inspiring. It makes me want to do better work. And for that, I thank you.

[@TommyJobson]

Thank you that’s wonderful to hear.

[@LikeFactoryMade]

This channel is severely under rated. You are doing an amazing work! Congrats!

[@SlartiMarvinbartfast]

Agreed, this is quite possibly the best clockmaker channel on KZbin.

[@mfx1]

Nice work, it would have ben nice to see the soldering process as well.

[@neilward5968]

I agree, I wanted to see that as well !

[@september1683]

This video gives me hope that a few percent of people have escaped the dumbing down of the last 50 years. Please keep it up!

[@andrewwolf4430]

That old lathe is beautiful and astounding

[@sleepywombat2751]

Nice jig and a lovely little Schaublin. Very enjoyable viewing

[@624Dudley]

What a nice way of saving the majority of the original material. 👍

[@Kairosdex]

You are a genius.

[@bkoholliston]

That's a very clever repair and the result is just beautiful.

[@cristianvera8506]

Just simple “genius “ 🙌👏

This is becoming a lost art. Well done.

[@JeffRAllenCH]

Thank you for taking care of our heritage. Salut from Vallée de Joux.

[@markhammerschmidt5315]

Flabbergasted frankly. So glad I found this channel. The workmanship and video production is stunning. I also love the sound of that clock in the background.

[@lutzderlurch7877]

certainly looks like a splendid job well done, also well filmed and narrated.. makes me want to send you my favourite verge fusee pocket watch..

[@mikebenda1061]

Excellent master craft skills,thanks. Gives joy that you found the “time” to keep it original. Your patience is calming. Great editing also.

[@halnwheels]

I had the pleasure of using both a Schaublin 80 and 102 at a prototype machine shop back in the 1970s.. I agree with everything you said about the tactile feel of these machines. The 80 in particular, was used by a machinist who I watched make pressure diaphragm caps that were .080" in diameter with various diaphragm thicknesses as thin as .0012" across the diameter. I was at his house one time where he showed me a clock he made himself with a siderial complication. It wasn't until later in my life that I came to realize how close I was to a very special talent. This video brought me right back there. Thank you!

What a pleasure to see a craftsman at work, it truly was inspiring to see. Excellent!!! Subscribed

[@christianvalenzuela225]

I just suscribed.... your work is lovely❤ ....old retired dentist

[@SlartiMarvinbartfast]

I've always thought that dentists would make excellent clockmakers/repairers, also jewellery creation and repair.

[@ricardosmidt9600]

Thanks !

[@aaceytuno]

Wow, that’s intense ! Better than new , didn’t think that was mechanically ever possible

[@robertogattoli]

Very well done!

[@bobdavis5216]

Thank you for the time you put into making the videos, much appreciated from the other side of your camera. Nice to see a repair rather than a replacement, especially one so skillfully done.

[@RB-yq7qv]

Hi Tommy. Very nice repair work it should be good for another 100 years of service.

[@istvankis4089]

Respect!

[@steveparker8723]

Just amazing!

[@odiesclips7621]

One of the most unique, fascinating videos I've ever seen. The specialized machinery used to cut gear teeth is captivating. Thank you!! Very well done.

[@ZeRossetto2004]

Congratulations from Brazil!

[@KeritechElectronics]

That's some beautiful gear! Both the clock part and the shop equipment :)

[@mackk123]

my grans had all her teeth replaced too, bless her soul.

[@edwardashton7502]

brilliant, so facinating.

[@gerritvisser]

A great visual explanation of the whole process.

[@ianswindell]

Nicely done

[@anthonymarino4260]

A GOD GIVEN SKILL. WELL DONE

[@chrisjohnson4165]

Perfect job! Thanks for taking the time to let us into your world. I'm an instrument repairer so I love to see other craftsmen at work.

[@lordofelectrons4513]

Excellent work! I would like to have seen the soldering procedure use on such a heat sensitive component.

[@y2ksw1]

I just had a flashback. As a joungster I built tiny mechanical devices for optics to be mounted on a satellite. We haven't had such good tools and some pieces were extremely challenging to make.

[@gmendes1831]

Nice job!

[@balaurul100]

O my God. I am rarely impressed... thank you KZbin algorithm ! Thank You for this. Subscribed. 10 times over if I could.

[@hjhammhjhamm2385]

Flawless!

[@chopper3lw]

Masterful job! The order of operations was surprising.

[@feraltweed]

I just had to watch after seeing the title of this video. I took a two year class in watch and clock repair about thirty years ago in plainwell Michigan. One of our projects was replacing a tooth on a wheel. I told my instructor I could replace all the teeth and keep the wheel. He looked at me like I was nuts. That night after school I went back to class and did about the same as you. However instead of making a blank and recutting all the teeth I cut another wheel of the same kind so the new ring gear would solder nicely onto the turned down original. It did not look as nice as yours but it worked fine. I think my instructor was impressed

[@johnkemas7344]

Beautiful job of restoration! Always a pleasure watching a master craftsman work. The precision of watch and clock work machining always astounds me!

[@WilliamYaughn]

What a brilliant solution for repairing that wheel! Excellent job with the video as well! Congratulations!!

[@scottthomas5999]

Wow! Nice work!!!

[@seannash4695]

Well done.

[@heighRick]

Thanks for the video, helps a lot! Appreciating the engineering, video and audio --Thanks

[@rogerdavis5914]

What a craftsman you are sir, brilliant video thank you for posting

[@69dblcab]

Nice video. Thanks for taking the time to share it.

[@markkrick8602]

Very impressed with your work. Looking forward to seeing more from you!

[@jrkorman]

This video just popped up on my suggestions this evening and I am happy for that! Wonderful work. So good to see repair instead of replacement.

[@tonybell4447]

Super work Very impressive

[@weejohnoo]

Lovely Jubbly! Thanks for the video.

[@bfx8185]

This is better like meditation !!!! Thank you! Really professional work!

[@zefdin101]

Diabolical ! Very well executed .. I loved it!

[@ace9xx]

I say that the whole video is played backwards to trick us! Joking of course. Very nice job and I'm now going to check out the other videos on this channel.

[@pdrg]

Good method - keeps concentricity etc :)

[@smalcstein]

Great work and thanks for sharing!

[@johnvaluk1401]

Just came across your channel. Wow! Thank you for sharing

[@StripeyType]

I must be feeling a bit fighty today - "I'm going to make you replace all your teeth!" sounds like fighting words. XD

[@KevinWoodsWorkshop]

Nice work Tommy.

[@yosacfc]

Good work!

[@Weeping.F]

what a ancient lathe!😯

[@SlartiMarvinbartfast]

Old is sometimes good. 🙂

[@Weeping.F]

@@SlartiMarvinbartfast yeah, I agree

[@slawomirmateja166]

Perfect Tommy, you are a master, you have beautiful machines. I wish I could work like that. It looks beautiful and I'm a little jealous of you. Kind regards

[@tasmedic]

Interesting that you use forceps to remove the screws from your holding tool, but fingers to replace them.

[@chrisstephens6673]

Excellent job, you seem to have solved the restoration/conservation/ preservation conundrum by getting the balance spot on.

[@markgoddard2560]

Beautiful work. Subscribed.

[@inertproductionsalternate9114]

Im curious as to in what cases this type of repair would be preferred over making a new wheel? Detailed wheel repair where it would be difficult or costly to replicate perhaps?

[@leedale4008]

You are a very skilled man,if I had an hat I would take it off to you. 👍

[@docle996]

genial

[@jimad]

Wonderful job! Could you share a few words about the soldering process - must have been quite tricky. Thanks for sharing your work.

[@TommyJobson]

Hi @jimad and @PatrickSpencer, unfortunately I had a nice clip of setting up the camera and no footage of the soldering part, so sorry for the omission! I basically sweat the smallest amount of solder at the lowest heat I could manage to get it to flow taking care to shield the pinion to prevent heating it.

[@spc0553]

Superb skills indeed, I spring to watch. I would love to see the Gents Pul syn etic master audible in the background ! Not of the same fine quality but built to last. Mine was made in 1931, has been installed at home now for 36 years and keeps excellent time, within 2 seconds per week.

[@spc0553]

I spring should read inspiring...sorry

[@TommyJobson]

It is in one of my earlier videos, but I might do a dedicated walk through of it one day.

[@cncshrops]

Very pleased that The Algorithm has finally suggested your channel. 1new subscriber 😊

[@LCMNUNES1962]

ÓTIMO SERVIÇO EM MICRO MECÂNICA de RELÓGIOS 👍👍 🇧🇷

[@Tasarran]

I'd never make it as a clockmaker; I can barely even see the problem! :D

[@danielkaylor8395]

Exelant work but I would like to have seen your soldering process !

[@TommyJobson]

I lost the footage of that clip - sorry!

[@davemartin2068]

Wonderful work. You must have spent a lot of time getting to this stage! Where did you find that beefy pair of tweezers? Got to say it again, wonderful work.

[@steveklopfer4780]

Nice to have all that you need . piece of cakies

[@thomaskrenn3808]

👍👍

[@syedsayeedurrahmanzaini4221]

How much did you charge for this flawless job?

[@aeroearth]

What type of solder did you use to attached the rim to the wheel? When fabricating small parts out of brass I prefer to use high temp silver solder containing 45% silver. When fabricating model aircraft tanks from tinplate I use low temp silver solder comprising 97% tin and 3% silver. Some 50% stronger than traditional 60/40 lead solder yet melts at a lower temp around 220 degrees C. If you used 45% silver solder to attach the rim you could make a heat sink out of aluminium or copper clamping on the wheel spokes to avoid tempering the pinion gear and shaft. Another method could be to bevel the wheel edges then swage the rim into the beveled edges and then face to final width. Likely add three brass rivets at the intersection of rim and wheel with rivet holes countersunk each side which would ensure the rim could never slip on the wheel. Avoids heat and the risk of distortion.

[@TommyJobson]

It was a reel of ‘soft solder’ the rest is unknown!

[@DrHarryT]

Before watching the video I say to machine the teeth off and reduce the OD of the wheel by at least .030 create a ring the same thickness with the OD larger than the teeth points and an ID .001~ smaller than the wheel OD, Put the wheel in liquid nitrogen and heat the ring. Then have it set up to punch the wheel into the ring all at once in an instant. Now just machine new teeth onto the ring OD exactly the way they need to be.

[@DrHarryT]

I didn't think about the fact that it's brass and you could just solder it.

[@Rouverius]

Beautiful repair. Honestly on camera, I couldn't see the seam.

[@ernstlessau8208]

I am also could not see that seam - and I also was missing the actually prozess of making the comination between that to wheel 's. Not only 1 picture about that connection process was to be seen.

[@garymucher4082]

Amazing patience and intricate work. Have you weighed the before and after to see if it weighs the same or very closely? I was wondering on such a delicate gear if the weigh would change the operation... IDK But Thumbs Up for sure...

[@abnermiller9489]

Great question. I would like to know too. Thank you for your question.
