- The pivot is 0.24mm, the pivot is bent or broken, the wheel cannot be replaced. The solution: Drill the old pivot out - fit a new one. But first we need a center drill guide or it will all go horribly wrong.

0.0094 inches. . . . Wow!
Watch Repair Channel hello ,sir. I’m from VietNam . English is not mother language in my country . I really want to be like you , i want to be able to repair watch . Please help me !
Great music!
do you have a video explaining what magnification rates you use and the types of magnification equipment used in your work?
Hi
My name is Huy
I asked you to remove the hair ring of the machine 7s26, 7s36. Can you please help?
I compared what you just had done to a work of art. This is not fixing, this is true craftsmanship and immense patience. Thank you sir for showing us your art and craftsmanship.
Fantastic craftsmanship! That was most interesting to watch....Nice to be able to produce parts "in-house".
The trouble with the amazing macro work in the video is that you really don't get a sense of just how small these parts are! Great work Mark, beautiful craftsmanship and excellent videography.
very true.
I'm thinking "wonder how large that lathe is" and then your *thumb* moves into shot and puts everything into scale. Just amazing.
Many thanks for this video, it has given me renewed inspiration to get on with the repivoting of a 4th wheel on an old Rolex Prince 300 movement I have been putting off for a couple of years! Excellent as ever Mark.
Mark, very well done.... I love the videos. Been a long time since I've been to the forums- hope to rejoin the watch repair enthusiasts again soon
Incredible craftsmanship! Thank you for sharing this with us :)
Outstanding! Thanks so much for sharing with us, Mark!
if i may say, you are a metal wizard of the highest degree.. long story but when i was taking classes for applied machining sciences i asked my instructor how to do basically this and the response i got was " make a whole new one" im goin to email this video to him i think lmao courageous work there
he was right, doing this is an impressive feat but imagine you have to charge a customer for this work, i will result in a heart-attack bill 😂
Wow, absolutely amazing to watch.
I'm always marveled watching you work Mark. Thank you for another awesome video. I'm going to have to sign up for the 3rd video course soon.
Another excellent video, thanks Mark
Awesome video! Now to go try this on my drill press for a really beat up ETA 7750 I got for $85 out of the bottom of someone's parts bucket. (All the pinions are broken off) Was sad to see it in such bad shape. But I think I can make it run. Thank you for all the videos you make! First comment on one but I've watched most of them over the last several months or so trying to learn things, and have you to also thank for getting me into this horology hobby after I watched one of your vids about the 2836 or other movement back then. Now I have an old metal tackle box I hosed out full of watch/movement repairing tools (the basic stuff) and spend half my free time learning what oils do what and searching around for even more tools lol.
Parabéns, seu trabalho é uma arte
Beautiful work. I think it's time for you to create your own watch from scratch! Thumbs up!
Genial trabajo, es muy impresionante!
Incredible work. The machining work was very impressive.
thanks
Superb Mark. You are a fantastic craftsman. Enjoy these videos very much.
Good job, Mark. Thanks.
Well done! Would that we all had your skills!
Absolutely loved this Mark. I'm away out to buy a lathe now!!
This was a joy to *watch.*
Good video as always!!
Unbelievable work!
When you say good bye, say this: Thanks for watch-ing! :)
Nice, thank you and very nice to see an Unimat SL in action.
I can't believe I just watched you drill a hole in the center of such a tiny piece of steel. Amazing how delicate and small those pieces are. I wish you'd tell us how much these jobs cost.
Absolutely superb.! Len.
I can believe it you're so good in your job !!!!
Brilliant video providing a tidy solution to a potentially big undertaking. Beats making a complete new shafts... Especially for novices. Trusty EMCO Unimat 👍.
Thanks, good tip on making a centering hole. The jig seems to be to keep the graver from floating. I'm going to try using s small graver, might be able to get sufficiently close to avoid making a jig.
You make it look easy, man.
Nice video and good music to go with it.
Makes me want to pull out my flytying gear seeing that small fiddleing going on 😀
Você é fantástico!
Super job!
At first i was puzzled . "How is he going to fix it , what is he doing ?" . I tried to understand . Then my penny started dropping and i went :" oh no , is that possible ? " . How can that be at that scale ? But apparently it is . Well , that is amazing . It is a good thing that such repairs can be done , many old beautiful watches can survive "through time" this way . Good job . Erwin , Belgium .
Very relaxing vid. 👍
I really enjoyed that.
Bravo maestro
you sir are amazing.
good job !
Nice video to watch, new here. You do good steady work on the micro machining level. Turning down the over-sized available pivot material we fun to watch, can he do it? YES.
Great but of engineering skill on show there sir. Did I see Silver Steel and Ground flat stock being used there? My company produces that here in Uk.
Really enjoyed watching this. As always you are an inspiration for me.
Nothing short of genius!
wow u are professional
Fentastic. Very intrested
Thanks mark 😀🙋👏👏
I'm not sure which was more satisfying, watching the video, or adding a 'thumbs up' and watching the likes counter go from '999' to '1K'.
Mark,
This may actually solve a problem I have with a Escape wheel pivot. The movement has no markings other than a K so I am having issues finding a replacement. I am taking your watch repair course and I haven't serviced 1 movement as of yet, I did win several from eBay which should be here any day. I want to service all 5 before moving on to course 3. I've learned so much from your first two courses, and am very grateful you put so much time and effort into producing them.
Music well-suited to the task at hand :-) nice, well-founded video.
Amazing sir
I do some metal turning on a 12x20 lathe. Man, that was bloody brilliant!
As ever, VERY interesting videos! Ever thought about induction heating? It would work only on steel, but is very localised, and easily achieved by a very small coil of copper wire , two or three turns wound around the pivot (loosely) and AC current applied. Common in the motor industry, (on a much larger scale). You would get the pivot hot, but not the brass wheel, as the induction does not work on brass. Softening the pivot may then allow straightening without breakage.
Á1www
bravo. As a one time (macro) machinist, this work is incrediblw!
Great work it is not so easy even to think, but very rarly like u.I very much impressed ,I also do many items like this since I am also mechanical engineer & watch repairer by hoby, it is easy replace but by doing ourselves gives lot of satisfaction.
Good job mark
Many thanks :)
AMAZING!!!
merci pour cette vidéo . très bonne idée , je pense de le réalisé pour mon vieux tour Lorge a pince 8mm ..
...amazing...
Speechless
That looked like fun. I have never seen such a tiny drill. I suppose those snap pretty easily.
impressive
lon time no see-thank u sir for all your vcedio
Great as usual!
What is the most expensive watch (estimated) of your repairing experience?
Thank you I have been wondering how to do this
Give it a go
Enjoyed that, thanks. Do you sharpen your own drill bits ?
Superior work.
Your videos are great. Your style of teaching of patience and depth is great. As a 16 year old apprentice in 1976 in Sydney, I did not have this type of instruction. Great work man. Thanks.
Nice
Make a video, where you show us, how to paint / make custom dials, would love that!
Wonderful, I wish if you were living in Montreal/Canada to cooperate with you on a daily basis as I am a watches collector, especially the vintage, highly valuable watches. Thank you very much , your effort to do these very interesting videos is absolutely highly appreciated. Dr A. KHATIB
I'm a tool maker by trade,and I reckon that was bloody impressive!
cheers ;)
Wow. Just Wow
Love the music
Mark, amazing video as all the other ones.
I am very interested in repivoting and I would like to know how you make the 3 flanks drill appears in 6:57 min (I suppose is a homemade tool).. I have tried several times but I do not get an accurate 3 flank profile as you. Should be possisible you complete this video with a procedure to obtain this tool???
Thanks for share all this knowledge.
REgards.
Eccezionale.
Hello,
I really like this video of yours!
Where did you buy those Drill Bits?
I am speechless!
nice job ! reading about it at school vs real life example wauw
When searching for parts to make your own watch how do you tell which size dial to get or movement.. will it list the case size it fits in or the size of the part?
Amazing video, but the music was phenomenal
Hey!
New subscriber here. I'd very much like to see you tackle and show us how to paint/ make custom watch dials. Perhaps with a DIY screen printing machine? I have a dial that I'm trying to get made before Christmas but all of my Chinese contacts aren't getting back to me with a price.
Keep up the fantastic work!
Amazing work!! Unfortunately in my city, watchmakers hide from the public and none so far, will do custom repairs like this. I know… I’ve tried:(
Super
Amazing. So glad I found your channel. Is it ever too late to apprentice?
no, follow your dreams!
This is amazing skill. I hope you can shoot Rolex3235 teaching video!
Excelso
Great work!!!!!!!!!!!
Another great video, thank you. As an aside, is there anything that can be done to demagnetize an entire milling machine or lathe?
Harvey Johnson rebuild it entirely of bronze.
Greetings, I have a JULES JURGENSEN 14KT gold watch manual wind SWISS with the date only window at the 3o'clock. I cannot figure out how to open the back case to locate the serial number and any other nomenclature. Are you able to opine as to a method to open the back case.?
Thank you. What kind/make of drill bit did you use?
Those small drill bits are Carbide.
It seems loctite 680 or some similar, greenish, for-tubes kind?
do you do pivor repair services? i have an 1850 mobier clock but the crown wheel escapement is broken.
Also, will you need to temper the new pinion? If so, that would be a very interesting process to see.
No - using pivot steel is already hardened and tempered.
WOW! And you were able to reduce the diameter! First Rate!!
Interesting work, congratulations. A question, once the stump has been inserted (I am referring to the 11:03 minutes of the video), how did you remove the excess part without creating wheel problems? Thank you
lio
Excuse me I was referring to the minute 10.10 of the video.
Do you happen to sell these guides?
Life hack: you can use a magnifying glass when watching these videos. Amazing view :)
so what would the safe to straighten axle shaft wheel (e.g. a lighter)to heat the axle up to red and let it cool down (so metal opustitsya and become soft) after you straighten and also heat to red sharply lower into the water (so, again, we temper the metal and he will again be strong as they were in the beginning!!!
Great video,I have a fourth wheel with a broken sub second pivot. I do however not have the equipment or skills to do this ;-). Do you know where I can have this done so I can get my precious Cortebert working again? I am unable to find a replacement wheel.
What is the new shaft material
