Pleasure. Glad you found it useful. All the best :)

:) Thanks. Don't forget the others in the series so you can see what it becomes. Cheers

Thanks Mars :)

I used the finest music wire (sometimes known as Piano wire) made by K&S Metals. I buy it from model aeroplane stores and it is quite cheap. Cheers

Chris' videos are amazing. Been a Patreon supporter of his for a number of years :)

@@danielkemp4860 Thank you :)

Thanks, hope you found it interesting :)

And thanks again :)

Thank You :)

Glad to help Benny.

I cover that process in the video from 14:40 - 16:35 Cheers.

Thanks :) Videos on engraving/printing are on the 'to do' list. A watch my dad has, from 1745, has a watch paper in the outer pair case from a watchmaker to British royalty! Fascinating things. All the best with your pursuits.

Thanks :) I'm constantly amazed at what skills people developed with minimal tooling; just time, patience, and aptitude. I don't want to see those skills lost. Part 3 is better, as I made some discoveries/improvements to the way I was doing things. Have a Good New Year.

G'day haipham, to calculate how many beats an unknown watch requires, I'm quoting from Saunier's 'The Watchmaker's Handbook' from 1880: "Multiply together the numbers of teeth of the wheels, starting with the one that carries the minute-hand (which therefore makes one revolution in an hour), but exclude the escape-wheel. "Multiply together the numbers of leaves of the pinions, commencing with the one that engages with the centre-wheel. "If the first answer is divided by the second, the number obtained gives the *number of revolutions* of the escape-wheel in an hour. "Multiply this figure by *twice the number* of teeth of the escape-wheel, and the answer is the *number of single vibrations performed by the balance in one hour* " If you have remains of the original hairspring, measure it's thickness and width as I did in my first hairspring video (link starts at the right spot kzfaq.info/get/bejne/nLNnp9Z4vrSlgJc.htmlsi=R--r9YiFW5nwqQaf&t=610 ). Make the new hair-spring one or two coils too long, as you can always shorten it, fit to the watch, time it, and shorten as required. I put the watch to my ear, and count the tic *or* the tock, while running a stopwatch, for 60 seconds. I then double the result (so as to count both the tic and tock), and then multiply the answer by 60 to get the number of beats in an hour. There are apps for Android that will listen to your watch and show the beats per hour; or you can set the beats you're after and it will show you how fast/slow it is. The one I use is free and called 'Watch Accuracy Meter' on Google Play. The three dots at the top right of the screen gives you access to Options. A word of warning: phones have very strong magnets in their speakers which can badly affect a hair-spring. I use a plug in lapel mic. (bought for around $20) to listen to the watch while keeping it well away from the phone. If you don't know how many coils the hair-spring should have, but many of that model watch were made, try finding images of complete ones that show the hair-spring and count the coils. The number of beats you're talking about says that you are working on very modern watches, with a lot of coils in the hair-spring. This is not something I've tried to do; 200 - 300 year old verge watches have only 2.5 - 6 coils, so are a lot easier to make. All the Best :)

Thanks Avian, I live in a rural town in Australia, which means getting specialised items can be expensive and take a while to arrive. It's easier, and a *lot* cheaper, for me to get to a model aeroplane shop (store) and buy the finest music wire they have and do the reduction myself. Also it means that if I'm ever in need of a hairspring for a watch, I can start work on it immediately, without having to wait a couple of weeks for the materials to arrive etc. And I enjoy making things from basic stock :) Cheers.

Thank you kindly

Glad you liked it Jason. What era watches do you make hairsprings for?

@@theselectiveluddite I make hairsprings for dials and indicators. I don't assemble them to the instrument, but I do put the collet on them and form the ends as the customer requires. My tooling uses stack winding to make the springs, so I get as many springs per winding as fit between two coils. Though I can't make as much volume as the automated companies, my quality has been better (that last is directly from my customers). My tooling and method is probably from the early 1900's. Think, repurposed hand-cranked drill.

@@jasondayon4702 Beautiful ! Gazeley, and I think De Carle, describe similar methods in their watchmaking books from the mid 1900's for cottage watchmaking. Well done :)

G'day Luis, It's just ordinary paper that we put in our desktop printer :) Cheers

G'day, the book is 'Watch and Clock Making and Repairing' by W.J. Gazeley, FBHI. Page 399. Cheers

@@theselectiveluddite Cheers mate, ordered myself a copy.

Thank you :) I have a number of things I want to cover, but unfortunately life has been very tiring and I haven't had the energy for filming/editing for a while. I will get back to it when I can. Cheers

G'day a.c.116, Sorry for the lateness of reply; we've been otherwise occupied of late. I wanted to use the methods that were employed at the time the watch I'm restoring was made, as I'm very interested in how things used to be done. I may make up a 4 spring curling box at some stage, in order to make later, 1800's, hairsprings, but the experimental archaeology side, using simple tools and relying on practice and patience, appeals to me :) All the Best.

Thank you :) Don't forget the other two parts, as well as the Makin' a Tool episode where I make tweezers to curl the hairspring. Also, Repivot 22 did a video where he adapted my methods and has a very good way of making the tight inner coils. I recommend it: kzfaq.info/get/bejne/e8ibZLerrZzbhas.htmlsi=cdXH1RXLFS4fW2pv Cheers

G'day tlmooney, the brass collet, that jambs up under the balance wheel, and to which the hairspring is attached, has a hole drilled in it, parallel to the top and bottom surfaces, and that enters and exits the outer surface of the ring (in other words, doesn't go through the collet from the outside to the inside) Hope this shows it: (IO ) Explanation: The brackets are the outside diameter of the collet. The vertical line is the drilled hole, which in a proper drawing would touch the outer diameter at it's top and bottom points. The 'O' is the internal diameter of the collet. The inner end of the hairspring is slipped into the drilled hole and a brass taper pin, often with one side filed flat, is pushed home to trap the spring in place. This enables adjustments to be made to the springs planar alignment with the collet, by gripping the end of the taper pin with fine pliers and twisting (after which the pin is snipped off flush), or complete removal for repairs or replacement, and won't affect the spring's temper as would the heat of soldering. Hope this was clear. All the Best. Cheers

Glad you liked it, Westerly. You do watchmaking as well as sailing? Cheers

@@theselectiveluddite I do! At some point I will upload my restoration videos of my 1971 Westerly pageant yacht. It's literally taking years. But I'm looking forward to getting her back out on the Sea one day.

@@sailwesterly5444 Good stuff! All the best with the project :) Cheers

Thank you; glad you found it useful :) Hoping life will enable me to make some new videos sometime :/ Cheers

:) Watch my 'Makin' a Tool: Hairspring: Hairspring Curling Tweezers' and then Pt. 3 of the hairspring making to see some improvements. Also Repivot22 has a better method of doing the tight inner coils. Here's his video: kzfaq.info/get/bejne/e8ibZLerrZzbhas.html Cheers

Thanks again Steve. So do I :) I have a *lot* of things I want demonstrate, and tools to make.

Thanks Steve. This year's not been conducive to doing much Horology, and less filming with being very flagged out, but hopefully will be able to do some later in the year. Cheers

G'day Samy, It's Music wire that I buy from model aeroplane shops (stores). It's the finest they sell, 0.015", and comes as a bundle of 5 strands, each 1 yard long. Only costs a few dollars. Cheers

Good question Stefan, I have no idea :) But that is no reason not to try, It would need to be hammer hardened to give it springyness, then brought to dimension, then curled; but too hammer hardened and it becomes brittle. It wouldn't be magnetic, a vote in it's favour, but how it would respond to changes in temperature is a big question. I'm guessing it's been tried at some stage in the past, and rejected due to poor performance, but you would learn things if you gave it a try. Make sure to watch Parts 2 and 3 for the rest of the info. as well as this video ( kzfaq.info/get/bejne/Zs5dYNF7v7a6dGg.html ) on how to make tweezers for the curling. Also, Repivot22 did a nice improvement of my method of making the tight inner coils: kzfaq.info/get/bejne/e8ibZLerrZzbhas.html All the Best.

G'day Paul, Sorry, lots of things requiring my time so I've only just come across your question. I'm afraid I don't have any experience yet of making Breguet overcoils. I've got charts etc in various books too on them, but I haven't had the time or need to study them yet. Trying to have the energy to film some more :) Cheers

Verge watches have the advantage of everything being more robust :) But, might still be worth tackling; would need more fine work with the Wet 'n' Dry paper stuck to paddle pop sticks to get it to dimension. All the best.

G'day htc. Glad you liked the video. My only concern would be that drill bits are on the brittle side, and when they snap, they chip, and things get interesting for your eyes very quickly, and you can't anneal HSS drill rod. I speak from experience. I had a drill snap on me and a razor sharp fleck lodged in the border of eyelid between the eyelashes and the eyeball, in line with my pupil. I was squinting at the time. I resolved that day to never drill without safety goggles again. The music wire I use is quite cheap. A 3 foot length, the diameter of the one I used in the video, would be around $4 Australian, and will make quite a few broaches, spade drills, balance staffs, and on and on and on :) All the Best Cheers.

Thanks for your reply@@theselectiveluddite. And thanks for warning about HSS chipping. I got some old watchmaking tools on my hands. On is quite large and rusty broach. I'd like to restore it even I don't really need it as it is quite large. I'll definitively will give a try for the method you shared.

@@htchtc203 Nice. I also have quite a lot of antique watch and clockmaker's broaches, a fair proportion of which have dull edges. You can see this by rotating the broach under a light. A dull edge will reflect light between the facets, where as a sharp edge will not show up at all. I used the method in the video (but with a hardwood block with fine tapered grooves at one end and holding the broach in my fingers) to sharpen a bunch of super fine watchmaker's broaches (like the one I show early on), using a very fine diamond hone (only about 5 strokes per face) followed by a small piece of slate. I used the method of pressing down firmly with the hone/stone to keep the face being worked on level.

G'day Vasilis, I'm still doing repair work on the watch (it was made in the late 1700's, and it's been a very full year so I haven't been able to spend much time on it). During the times I have had it running with this hairspring it's been able to keep to around 1 minute a day, which is very good for a watch of this age. Are you repairing a watch yourself? Cheers, and I hope you have a great 2023.

@@theselectiveluddite happy 2023, be well, I'm doing repairs on these watches too, I'm not a watchmaker, I really like these watches with this style, thank you

@@VasilisStithos I'm also in the early stages of learning watchmaking, and I'm concentrating on these older watches as they are much more interesting than modern ones :) On archive.org there are quite a few books on watchmaking from the 1700's and 1800's that have been scanned and are downloadable for free. Cheers

@@theselectiveluddite Thank you very much for the information

@@VasilisStithos Pleasure. Also check out Richard Watkins' site for a bunch of free PDF's he's put together of translated 1700's watchmaking texts. It was from him I got the text on making hairsprings: www.watkinsr.id.au/
