Here I am, in 2024, starting my learning and admiring your work. I'm glad TH-cam exists so I can learn from you. Please keep posting your videos because they will keep the profession alive. Thank you for sharing your knowledge, it is very valuable to me.
Good job , I am impressed at the steadynesss of your hand , breath control is a tough skill to learn as a young watchmaker , even tougher to maintain as a seventy three year old like me . I do have to take more breaks than I used to. One thing I do is to use a ruby or a sapphire for final polish and sizing. Once again thanks.
Thanks Larry, I also have more than 35 years of experience restoring old watches and clock movements. But last 20 years i have only worked with cross-support lathes, so I was afraid I have forgoten how to work on the t-rest. But, obviosly, it is like riding a bike...
@@nevenbekriev like you I rarely use anything other than a cross slide it's funny how you can become so accustomed to a certain way of doing things.. By the way what's are you from?

Hi Luis, thanks for the good words! Yes, I still do such things... Actually, i did this video for a friend, who asked me how to repivot a balance staff. It was easier for me to show with a video rather than explaining. But, there is something important - it is much beter to turn entire new staff than repairing broken one. And, sometimes it is easier too. I made the video to show that it is possible to do and to show one way it can be done, and never intended to suggest this is the right way for solving the problem... But I see now that people get me wrong...
Hi Chriss, The diam of the guitar string and the drill bit in this video is 0.25mm. Actually this way of repivoting is good for train and 'scape wheels, but is not that good for balances. I did the wideo as a friend asked me how to repivot a balance staff, and it was easier for me to show than to explain it in language, that is not native to me... The best way to solve the problem is to turn a new staff on the lathe, it will take (to a skilled man) practically the same time like the repivoting of the brokem one.
Hi, I did the pivot from a piece of guitar string. This steel is already hardened and tempered to proper for pivots hardness. No further thermal treatment is needed In Watchmaking usually steel must be hardened and tempered to blue priot to turning. After the part is ready, no thermal treatment is aplied. Hardened steel is easier to turn then soft steel - it will not bend and will give good and smooth surface. But You need tunsten carbide cutters...
Yes, this is not a secret. Einhell BT-ML 300. This i not a watchmaker's lathe, actually a big one. It is china made. But if You buy one, it will bi not ready for such kind of work. I have made to it alot of improvements, aditional utilities and accessoires.

@@nevenbekriev Здравей (Невен?)! Стори ми се, че свредлото е скъсено, просто питах как. Заточването на свредлото също не ми е ясно (ако наистина е скъсено). Както и как нагласяш ножа точно в средата на оста, която режеш като тя е 0.25мм :) Много въпроси станаха... Добра колекция от часовници, между другото. Аз също се опитвам да поправям като хоби и имам няколко със счупени баланси, но не всички мога да ги поправя. Поздрави и благодаря за информациятя!
@@nevenbekriev Thanks a lot!, I wanted to do it but I don't have a lathe and I don't know where to get one, and you were very helpful. I'll try to contact you and send some photos Thank you.

Supper. Impressed. Top work and skill
Show de bola 👍👏👏👏
Here before it gets recommended to everyone
Все больше убеждаюсь, что без станка мне дальше никак.
Hi - loved your video, it has given me direction. What diameter was the pivot wire (guitar sting) as I need to repivot a balance staff?
Hi Chriss,
The diam of the guitar string and the drill bit in this video is 0.25mm.
Actually this way of repivoting is good for train and 'scape wheels, but is not that good for balances. I did the wideo as a friend asked me how to repivot a balance staff, and it was easier for me to show than to explain it in language, that is not native to me...

@@nevenbekriev This answers my question. Was going to ask what factors would decide to repivot or to make a new balance staff
Hello. I am watchmaker from Estonia. What kind of needle or wire do you use for repivoting?
Hi there, this is guitar string. They come with different diams - 0.25; 0.28; 0.3...
I noticed your steel cut pretty easily. Did you re-temper the pivot after you finished?
Hi,

In Watchmaking usually steel must be hardened and tempered to blue priot to turning. After the part is ready, no thermal treatment is aplied. Hardened steel is easier to turn then soft steel - it will not bend and will give good and smooth surface. But You need tunsten carbide cutters...
Can you tell as what lathe do you use?His name ,please

Where did you get the drill bit?

But it is goot to know how to sharpen them...
@@nevenbekriev yes, yours seems to be shortened. how do you do that?
