Wow, this is a goldmine of useful information, thanks for posting this. One question, when you were correcting the 'out of flat' issue at 14:01 by grabbing with two tweezers you mention to "grasp with the tweezers and bend'. I'm not clear on what type of bend you are doing, how you are moving the tweezers. You are grabbing the hairspring with your left and right hand tweezers and in relation to the your left tweezer, the hairspring will want to be bent downwards to bring that part of the hairspring after the tweezers down as it is currently tilted upwards. Are you holding your right tweezer steady while pushing downwards with the left tweezer?

Thanks for showing all your videos ! Just a small basic question: what is the starting diamater you use ? the same as on the screw cutter, or slightly larger or smaller ? thanks!

very well done

Very nicely done, please continue producing these short videos, they’re real gems. Many thanks

Amazing

Why do all the teeth one groove at a time? Isn’t there a machine that can do them all at once?

Thankyou for a most interesting video I always enjoy them as I learn the most interesting ways of making gear cutters and wheels and I love the fact that you don't give up until you are satisfied and that's how it should be. Thanks again I really appreciated this. Jim from Australia.

Wow

I'd like to see something on proper shaping of the overcoil part that aligns with the attachment to the balance bridge and adjustment so that the spring is centered when reinstalled on the pivot and bridge.

Thankyou for an excellent instructional, very helpful. regards Geoff from Merimbula Australia

you're god, dude

Anyone know how you cut diamond lapping disks into strips like done here?

Just outstanding work! Thanks for sharing.

Thanks so much!

Puh that is a nerve wrecking work. There are for sure many attempts needed to get one out? The result looks good!

Phil you are amazing Ralph and I watched this we are going to share this with my family. Hope all is going well

Excellent

Excellent video! Thank you! KZbin content should be like this - very practicable and to the point, something anyone can learn from.

Thanks for sharing this. I do have similar problem. Just smaller movement.

Great video, thank you, at what RPM do you spin your lathe?

Making a great video like this is time consuming. We understand. Greetings from Ireland.

very nice, it's always very interesting and good for improve the skills

Not today, not tommorow, but some day I will get to this level :) great job!

Thanks for this interesting video! When you drill, are you hand holding the pivot drill in a pin vise? If so, how do you ensure that the drilled hole is perpendicular? I've seen another technique using a hollow handle pin vise slipped over the tailstock spindle to try and keep it steady.

Bravo! ZIM movement super simple for beginners who want to venture into the world of watch repair.

Fantastic job. Thank you for sharing it.

Amazing video as always. Do you source your blued steel from a US manufacturer? Are you able to share where you purchase from? Thank you.

I'm happy with another interesting video, greetings from Ireland

Wow! This video was exactly what I needed! Thank you for sharing your technique, tips, and tricks.

Estou tentando fazer isso a bastante tempo, muito difícil de alinhar e conseguir que fique bom

Me who currently is trying to figure out how to fix the hairspring from my great-great-grandfathers pocket watch (made around 1895).

Given the angle of attack of the contrate gear on the pinion I would expect to not be as smooth as the more common wheel gear to pinion action.

Fantasmagorical, excellent tutorial, I thankyou and so do my hairsprings.

What lathe are you working with?

2 years going and this remains the best video online for hair spring repair. Thanks for spending the time to make this

Outstanding. Hats off to you sir.

Where can I get the tools you used?

At 14 minutes I'm uncertain what actions are being taken with both sets of tweezers. Are you essentially gripping with both and rotating the opposite ends of the tweezers downwards to stretch the upper portion of the hairspring to bring about flatness?

Hi, beautiful video, can i ask you what module is the gear? thank you

10:30 To state it perhaps more balanced, if you find the point where there is the least and most deviation and look 90 degrees between them, you ought to be able, by careful inspection, see a point at which the deviation begins and perhaps see a flat or a clear angular bend, helping you to know exactly where to make your correction. You stated the best philosophy to use to approach repairs, no matter how complicated. First, make sure it is untangled (because it can be both bent and tangled. Then start at the center and make sure it is in round. No matter how many other issues there are, if it isn't in round, you won't be able to see them. So start one loop at a time and make it purdy. Then go back and work on making it flat. Then, lastly, address the final section where it must pass through the regulator and attach to the balance wheel. Step by step, one at a time, with patience and care, and you will end up with either a fully functioning hairspring or two hairsprings, in which case, you don't have to worry about straightening it anymore! 😅 I will also say that, because of the importance of a properly oscillating hairspring to the function of a watch or clock, it is worth taking the time to be something of a perfectionist as you do the work. If it ain't right, even if it works, there's no way it will stay in beat. As for the picks, it occurs to me that reshaping a set of dental picks would be easy enough and give a nice, touch working surface.

Fantastic work!

His voice is reassuring and tends to calm one down, which would seem to be necessary for this sort of work.

very nice stuff, many tools,,

i worked wit big lathes but those small ones are interesting hope can find a cheao one just for a hobby

Like

What an explanation and guide. Came across this as I have a hairspring to adjust. Thank you 🙏 Also how can we make these kind of hairspring adjustment tools that you mentioned in the beginning?

What chemicals do you use to wash your hair when you're done? thank you

3:04 that horn startled me haha

Wow. I just did my first disassemble and reassemble of a movement. I had trouble with the balance and messed up the hairspring, even though everything else went perfectly. I attempted to correct the hairspring under a microscope, but made it worse. This information is valuable, and I'll keep it all and attempt it again using this video as the hairspring is not near as bad as the one you awesomely corrected at the end. Thanks!

Hi Sir There is much to learn from you. I like it a lot
