Watchmaking Vlog 3 Making the Train Bridge for my watch


In this episode I’m turning this brass piece.
Into a train bridge So making the train bridge of this watch may
seem pretty straight forward process, but the real challenge lies in boring these holes
in their exact location, and when I say exact, I literally mean hair widths of error is unacceptable. So to get the alignment as exact as possible,
I’m using the Skoal Centering scope. Which is this tool right here. There are higher
quality and more expensive scopes out there, but his one definitely does the job. I purchased this tool thinking it was the
be all and end all. But in hindsight the same results can be achieved with a high powered
loupe with a cross hair reference. Or a wobble stick. These methods are described in detail the
book by George Daniels titled – watchmaking. Also Jere over at adventures in watchmaking
who is the pocket watch described in this book is using the wobble stick method and
explains it a bit more in detail. I have put the link for this book and Jere’s website
in the description below. So now that I’ve finished locating all the
holes on my workpiece. I need to turn the recesses in the brass. Before I can do that
I need to remove the original train bridge off the brass, by hitting with some heat. And then to get rid of the excess super glue. Once they’ve cooled down i’m going to drop them in some…..(acetone) I completed recessing the underside of the
train bridge, I took a measurement and it read 1.26mm and the original recess in 1.29mm.
So I have an extra 0.03mm for when I decorate the movement.
Now it is time to create the square shoulders for the screws to sit in. So this tool is
known as a d-bit , it is held in the tailstock and just plunged straight into the workpiece.
I’ve just ordered a new set of needle files, so I’m going to wait till they arrive before
I give the train its’ final shape and alignment pins.
It is now time to cut out the rough shape of the train bridge. I’m not the greatest
with the jewellers saw, so I expect a lot of broken .. (break blade) So here is the train bridge on the movement,
obviously it’s not finished there is a lot of work to do. I still need to insert the
alignment pins, shape the piece, final finishing, jewelling, bevelling. Still a long way to
go, but I’m happy with where I am right now. So I’m going to wrap it up here, it’s
been a pretty productive week. It’s now Saturday morning, I’m going to finish editing
and upload it. And keep the weekends as strictly family time. The vlog and the work that I’m
doing is definitely a after 9pm Monday to Friday type of arrangement.

  1. How are you liking the Cowell lathe? I am considering getting one with the wheel and pinion cutter in the summer. Excellent videos, keep them coming!

  2. Thanks so much for these videos. I've been waiting for a long time for this type of watchmaking series.

    Superb.

  3. Great watching your work, I too am a fan of Knew Concepts fret saws. They take some getting used to and very light pressure using them, you'll get the hang of it.

  4. Excellent videos! I'm excited to see where this journey goes! Also, excellent song selection. Can't go wrong with Ronald.

  5. I´m really curious how this series will continue, love the concept!
    It might be just my own perception, but the plates, bridges etc. seem to get a lot less attention in most watchmaking videos than the moving bits. Maybe they just don´t break often enough to get noticed…

  6. Dean,
    Before the invention of the Jig Bore, high precision boreing was done on a lathe using a face plate and toolmaker buttons. The locations would be initially laid out using a surface plate and height gauge. The precise locations would be determined mathematically and positioned by using micrometers and readjusting the toolmaker buttons. Once the button locations were positioned, the plate to be bored would be attached to the face plate of a lathe. The buttons (bore position) would be located with a dial indicator. After the button was indicated in, it would be removed and the plate would be drilled and bored to the final size. The size of the machinery was much larger but the process was similar to the one you are demonstrating.

  7. The Cowells lathe looks like a beautiful machine. I have seen pictures of them but have never seen one in the flesh. How long have you had it and what did it cost?

  8. Great stuff again. Always gives me more motivation to get off my backside and get the stuff I need to do something similar. Hopefully I'll be able to tidy up my own equipment (and fill in some missing pieces) and set up a workspace soon.

  9. Thanks for sharing my friend. Your videos are so encouraging and push me to pursuit the same dream as yours. Again thanks a lot from another fellow watchmaker in process. Thumbs up for you!

  10. Great work again Dean!
    Seeing this done is very worthwhile and gives a great deal more depth than reading "Watchmaking". It's an excellent book but seeing someone using the instructions is great!

    About the train bridge: the positioning pins seem rather critical to me. Wouldn't it have been more precise to press them out of the old bridge first, marking out the holes for them and them drilling the holes for the rest of the parts? To do it all in one go?

    Also, as I really enjoy watching your progress I hope that you mind your health :). Please don't heat cyanoacrylate glues in a confined space without very good ventilation. The fumes are really quite toxic.

    Best regards
    Karl

  11. Dean, good vids and informative. Whilst I may never make my own watch, its great to see someone else at work!

  12. i really apreaciate and trying to do the same!
    how much did you spend on that lathe?
    keep on going this way!

  13. Hi Dean,
    Thanks for your amazing video and looking forward to your next vlog!
    I was wondering if you could kindly tell me where could I buy a skoal centering scope…
    Best regards,

  14. Dean,
    A small boreing head is available with either an 8mm or straight shank. This will fit into your tailstock which allow you to fine adjust the cutter position. If I can ever get out from under the time crunch I am in I will make some videos showing some of my machining techniques. It is uplifting to see someone taking watchmaking past the level of disassembly, replacing parts, reassembly and adjusting. Keep up the good work.

  15. Thanks again for your video. This was very interesting. The cutting was nice and you added some laughs (for example "I expect a lot of broken…" SNAP), which add to a nice style when mixed with your nice music selection.

    However when you were turning the work piece you removed all sounds of the lathe. So there is no feeling for what you are doing. Mixed with the dark background it adds to a slightly grumpy or film noir like feeling. Maybe you can add some work sounds mixed into the music?

    Buuuut: This is just a very small thing and your video is actually produced very nicely.

  16. A very well made and informative video,hope to see more such watchmaking videos from your channel ,and good luck in your future projects.

  17. Keep up the good work! I am currently a watchmaking student in the US. Your videos are very helpful as another way of seeing a technique explained or performed. Very enlightening.

  18. Wow! Just stumbled across this channel. I am a mere amateur messing around with ETA 6497's and Seiko movements and putting pieces together with cases, hands etc sourced from eBay. The work that you are doing and your method of delivery is nothing sort of inspiring.. Only downside being that i can feel the credit card twitching as you describe your toolset ! Keep it up, man.

  19. Hi Dean, i´m spanish, and i´d like to start by my own in this business, you know manufacturating watches. And summarizing, you are so inspiring for me. Please, continue doing this kind of videos.

  20. Firstly you are so cute. Presentation is pleasing. You ought to have been a VJ.
    Being a CNC Mill/Lathe machinist I am humbled by the skill of watch makers of the pre CNC era. I never ever imagined this sort of precision is possible with manual machining. Your mission to make watches using conventional machining is legendary. All the best.

  21. Do you think this sort of prescision is possible with the ww style lathes? Second hand of course… The cowells lathes are too expensive for a student for my age…(13). Ambitions, ambitions.

  22. Dean, where did you acquire that coping saw that you use? I have looked everywhere for that saw and cannot find it. Thank you!

  23. can you please explain the tools more?
    can you recommend any lathes? and how are the holes tapered? it was mentioned ealier that the holes for the jewels are tapered. also how do you control the exact diameter? how can it be that the original bridge wasnt damaged if the holes are the same size and you did not drill the holes ready after removing the original bridge.

  24. Hi again Dean, I am on the adventure of searching to buy a watchmakers lathe. I watched your vid of 5 tips on buying a watchmakers lathe, but in this video you have changed to the Cowells 90CW Watch clock lathe. I would like to request for you to do a short video on your experiences of using the Cowells 90CW lathe. How having / using a NEW lathe compares to a used lathe. The attachments you think will complete the watchmakers lathe setup. Also, as I am an absolute beginner, maybe getting a cheap used lathe to begin a journey will teach me all the mistakes I have to learn before hunting for new equipment. Additionally, do you know what other companies still make watchmakers lathes and parts?

  25. I have to admit, anybody that can make watch parts gets my highest respect as being the ultimate machinist. I have been a machinist for over 40 years, I love and appreciate the level of precision required to perform the tasks at hand. Thank for sharing. Thumbs up and subscribed.

  26. Muito bom, sou Relojoeiro em Apucarana – Brasil e sou admirador de seu trabalho suas ferramentas e maquinarios. Custa muito caro um torno Relojoeiro mais simples?
