The real magic is using that much super glue and getting none on your hands.
Like watching a latter-day Horologist Faberge at work. Few could afford a skill of that magnitude, but if they can, it’s a life-times reward.
Excellent job! Watching a true clockmaker making parts to restore clocks to their former glory is fantastic to watch. Thank you 👏.
Thank you very much for the kind words. I’m very pleased to know you find the videos enjoyable.
mesmerized every time!
Im not a watch maker, hope to be reincarnated as one, if anything Im a machinist, when I first saw that escape wheel I wondered how on earth you would make that, now I know, amazing. Thank you for all the effort in making this video
Very nice 👍🏻 I hope this kind of workmanship will survive in our digital age
everything about CNC machining is safe 👍
Brilliant work marvellous
Thank you.
Just in time, I need a bit of escape this afternoon.
Sorry for the pun but thanks for the relaxing video.
Glad you enjoyed the video.
Tommy
This is a super valuable resource for anyone wishing to do this. Nice one!
Reuben
Thanks Reuben, although it’s not intended as a ‘how to’, it’s still nice to know the video will be of use to others.
@@TommyJobson the keen observer will take many tricks.
Impressionante! 👏🏽👏🏽👏🏽
Fantastic. Thanks for sharing
Very very very good work.
Respekt 👍🏼👍🏼
Awesome video!!
Thanks Tommy for recording such a great video. You are a great clock maker man. Very happy to find your page on Instagram and following you on youtube
Thanks for following along.
Winterataan? Awesome!
Amazing video, thanks a lot for sharing!
Thank you, you are very welcome.
Nice work Tommy, interesting to watch.
Glad you enjoyed it
Super professional work! Thanks :))
Thank you! Cheers!
Very intricate work another nice video.
Thank you very much!
Great angles and clips for this one!
Glad you enjoyed it
Thank you MASTER
Работа очень крутая! Но не проще в таких случаях пользоваться лазером?
Amazing job! Crossing guide is something new to me.
I appreciate your choice of wristwatch, I also wanted this model. In 7750 we trust.
Made it look easy.
thanks master. best regards
Thanks for sharing.
Thanks for watching!
Bravo!!!!!! Super!!!!
Thank you!
wow, respect
Very impressive.
Thank you! Cheers!
Genio !!!!!🤩🤩🤩🤩🤩
impressing.
Чудова робота, приємно дивитись!
Hate to get the tooth count wrong after doing all that work. Thanks for showing how it is done.
That would be a bad day for sure.
@@TommyJobsonbut raises the question I had, why not cut the teeth first and then file. Teeth can be protected while filing.
A great job Tommy, and a great video that highlights the time taken....and numerous processes required to create such a perfect thing, and also the tooling you've had to make that is needed to do the job. Why things sometimes cost more than assumed. 👍
As it looked complete....was it still performing correctly and just looking tired, or was it giving problems?
Thanks very much Neil. The old wheel was worn, it would have run, but when the tips of the teeth are worn rounded the impulse to the balance is reduced and it can when bad enough cause the escapement to 'trip' by not locking properly.
Superb craftsmanship, Tommy. I'm pleased to see this kind of work is still practised today. John Harrison would salute you. And so would John Arnold and Thomas Earnshaw!
Thank you for a great video.
Sir you are an impressive human being. The depths that it takes to get the result are absolutely Brilliant. I doff my cap to you. Excellent job. Thank you and God bless you for caring so much about the quality of workmanship needed. 👏🙋♀️
Thank you!
Couple of questions, Is the green layout fluid a choice, or is it aged to that color? My dykem "steel blue" appears more blue/purple... And Is that goma laca you're using to heat cement? laquer gum, or shellac flake, I imagine there are several names. Beautiful work, I like the crossing guide. I have been working at crossing out some wheels, achieving consistency and symmetry is a challenge.
Thanks for an excellent video!
Could we see the chime responsible for 'The sound of silence' in a future video?
That was a customer repair no longer in the workshop.
I'm aprendice!!
Wow! So that's how it's done. It looks like the teeth are thicker than the rest of the wheel which makes it more complicated. When you were crossing out at the end you used a piece of peg wood to polish - were you using diamantine as the polish? I thought it was great without the narration - just showing the work with occasional words of explanation on the screen. Nice job.
Thanks for the feedback, I'm glad you enjoyed the video. I was using Autosol on the pegwood.
Hola, 😊 entonces asi se fabrican las ruedas de escape en los relojes de pulso y bolsillo, gracias, por enseñarme como fabricarlo, podrías decirme que herramienta usas bueno ara hacer los dientes 😊 por favor
I think you can shave brass with an exacto knife...
Thanks for the comment.
😍😍😍
It is not often one can identify a clock solely form its tick, but that is definitely the ker-clunk of a Gent's Pulsynetic master clock in the background. 14:20
I think you have answered your own question on another video!
@@TommyJobson Yes watched this one first though.
What is the meths that you used with the boric acid. I have used alcohol but I always have some oxide where it doesn’t cover well as I heat. Great filming!
Thanks very much. It's Methylated Spirits, as sold in the UK. I've had good sucess recently preventing scaling like this.
When Harrison built his chronometer, would he first have to build the tools reqd to ensure its accuracy?
Hello Tommy,
An enjoyable workshop Wednesday, thank you. Could I please ask, I see that you use superglue, did you ever use shellac? if not is there ever a circumstance that you would? I was not sure if that was shellac when you did the crossing out. See you next time.
Take care.
Paul,,
I was wondering that as whoever made the original wouldn't have had superglue.
Well spotted Paul, yes I used shellac to hold the wheel to the crossing holder. Before the days of super glue it would have been either wax or shellac, it works in the samee way, CA glue is just a bit more convenient.
Cutter module? Aquisicion? Brasil. Good morning MASTER!!
The gashing cutter was ground to suit, and the straight cutter was a multi tooth ratchet wheel cutter, but only using the edge of it.
How would this have been done in 1870?
With a steam, or donkey and carott driven lathe from 1870
god I want a 102 so bad, trying to find cheaper alternatives with wheel cutting capabilities but there doesnt seem to be much out there
Tommy, what is "meths" that you used with the boric acid? Is it methyl alcohol or something else?
Methylated Spirits, as sold in the UK.
How much does a clock have to be worth to replace a $500+ escapement wheel?
Brilliant work. That is not an easy wheel to make,. When you only have a worn wheel for a pattern how do you decide on the final shape to make your cutter as if you follow what you have you will make another worn out wheel?
Thanks. You are right, it is one of the harder compnenets to make. The wear is pretty easy to see so the cutter can be ground with that in mind, but a judgement does need to be taken when deciding the OD of the new wheel as wear to the tooth tips needs to be accounted for. Judgment and experience are the tools for this!
У Вас можно заказать такую шестерёнку?!!!!!!!!!!!!!
I'm confused about why you make the crossing guide... Couldn't you use the same kind of transfer process directly onto the new gear and cut it there? Just seems like you had to do it twice this way...
i have a simple question/ how do you get paid for all this work? I see magnificent old clocks sell for $50 all the time.
why not just program a CNC machine to fabricate the entire wheel from start to finish from a blank .... your skill is lightyears ahead of anything i could ever do, but even so your methods are 300 years old .... however it was nicely done .... i am always in awe of any man whose hands never tremble in very delicate situations
Thanks. There are some things that CNC is not that great at. Obviously a cnc machine could be set up, but for the scale of this it would be tricky. Part of my purpose in life is keeping the skills of the horologist alive, and this particular job was given me with this very purpose in mind.
@@TommyJobson
Как с Вами связаться??
Можете Вы сдалать такую же?? Спасибо!!!!!!
Great job, but I miss the narration.
Noted. Glad you enjoyed the rest of it though.
Módulo?
How much do you charge for just one??? I need 10,000 of them in two weeks...
Thanks for the comment.
sorry.. METHS glass jar..
what does it mean ??
Methylated Spirits.
I think it’s called denatured alcohol here in the US.
All that time videoing and we didn't get to see a closer view of how you cut the teeth being created???
Thanks for the comment.
I don't think I can make this
CAn't see what you are doing because your hand(s) are in the way......
