Excelente explicación estoy fascinado con ese tornito tengo uno casero de joyería pero quisiera un tornito sherline y hacer ese tipo de trabajo de relojería
Great video. Kind of still a newbie so I have some questions. What’s the purpose of the heat sink vs just heating the part directly? What’s the smallest diameter pivot you’ve done with this method?
The heat sink allows the metal cool slower so it softens, otherwise it will cool too fast and won’t soften the metal. This was the smallest pivot I had done with this method.
I'm a clock repair man myself. Not nearly as good but. I recently had a worn pinion on a French whell. Due to the governor fan slipping. I just not a comfortable on a lathe. Is there any tricks you know to using an add a pivot? It on the gear side just like the one you restored. Ive learned quite a few helpful hints and tips frm watching. Keep it up. Thanks for the complete beginning to finish videos
A lathe is pretty much required for pivot work. You can send your gear out to be re pivoted. There are people who provide that service. Call merritts and ask for someone. They can suggest someone.
@@Chrisclockrepair thanks for getting back to me. I have a small lathe that was given to me from another clock man that passed. Time to start learning. Do you have any online classes or anything else. I've been repairing for about 7yrs now. I'm self taught for most part. I've had a few piers show me some tips and tricks. I stay 3-4mths behind and need to get faster on repair of mantle and kitchen clocks. That's seems to be my bread and butter in this area. Grandfather's I tend to sell them a new movement if at all possible. Do you teach a workshop? Or would you consider it? Gladly pay for a crash course or just to watch how you do it. My father ran the shop for about 25yrs but concentrated on grandfather replacement and out sourced small clock. Now there's no one to do but me. Any help you could offer.
Nice work and nice video, congratulations. Personally I would prefer to heat only the shaft head, perhaps inserted in a perforated sheet so to shield the pinion, trying not to alter any possible heat treatment present in the teeth.
Yes,but there's a high possibility of the very hard drill snapping off and wedging in the hole as happened when a clockmaker friend offered to do the job. Took me ages to get the bits of carbide drill out. I then let the arbor down to blue and drilled with a normal drill, I left the arbor as it was and no problem running after pivoting.

Very useful. Great procedure and setup. Very well explained
Thank you.
Chris, this lathe re-pivoting setup video is awesome. Thank you for all the great video's.
Absolutely! You bet.
In admiration of your skills, cleverness and true talent . Always !
Thank you!
Glad to see you are back making videos. The pivoting that you did was well done, great video.
Thank you Paul! I appreciate the kind words.
Great work. Love the editing on this video ❤
Love :)
Great lesson today, thanks!
You're welcome.
Is it an issue that you soften the pinion and does not look like you re hardened it. Great idea on steady rest. Thanks
Hi Chris. Can you use the steady rest that Sherline sells for this procedure? I appreciate your help.

Any need to reharden that little pinion gear? That's if it got softened along with the process done earlier?
Some may argue yes, but there is no need.
The Pinion if softened would wear if not hardened again

Thank you for the explanation! @@Chrisclockrepair
Great idea Chris do you think the same technique would work for a platform escapement escape wheel 🤔.
Should work with any wheel. It’s an old technique.

Hi Chris I thought you did an amazing job with this video. I am wondering what you use for drill bits and your source. Thanks
I have a local tool shop that sells individual bits. It's called Production Tools in Southfield, MI.
Nice work and nice video, congratulations. Personally I would prefer to heat only the shaft head, perhaps inserted in a perforated sheet so to shield the pinion, trying not to alter any possible heat treatment present in the teeth.
That's fair. Thank you.
Hello
I have a Gustav Becker p42 movement with same issue.
Could I send my lifter to you for repair? Contact info?
I to am a clockmaker, your idea looks good but would try not to soften the pinion, using a tungsten mini drill
Carbide drills are available in sizes small enough for even watch wheels and will drill hardened pinions without annealing.
Yes,but there's a high possibility of the very hard drill snapping off and wedging in the hole as happened when a clockmaker friend offered to do the job.

Muy bueno,,,hay varias formas de hacerlo,,pero así esta guayyy.
