The Barrel Bridge Screws - Making A Tourbillon Wristwatch

This is the start of the most important piece of work that I have embarked on to date. I am producing a series of Tourbillon wristwatches and I'm filming the process of making the prototype! In this episode I tackle the barrel bridge screws which secures the three quarter plate barrel bridge to the mainplate!

Thank you! Looking forward to the next video!

Thanks so much for sharing. It's amazing to me to be living in a time where the absolute pinnacle of skill is shared to be viewed in the comfort of my home. When I was young great artists and craftsmen would not ever share the secrets of their skills. I'm glad those days are gone.

Such a shame that this series has'nt seen any more updates. It's been great so far.

Hi, great series. Have you moved over to a different platform for sharing your videos or have you stopped all together? Thank you.

[@JimbobPalmer]

Hi Paul, unfortunately I have stopped all together and this series will never be finished. Thank you for tuning in to the few episodes I did though!

[@TommyJobson]

[@ebaystuffandothers4398]

Dear Mr Palmer, Are you planning a new video release? I'm looking forward to the next video. Thanks for sharing!!

[@keithbrister1904]

Really nice, thanks for sharing. Quick question; do you think from an engineering perspective that you might have left the shank plain until the point at which the screw enters the bottom plate and just threaded that?

[@JimbobPalmer]

I have thought about that and I can’t think of any reason not to do it other than it would look rather odd 🤣 I stop a little short of the head of the screw so there is always a small section not threaded but it’s not too much of a task to thread that much. Maybe if I was making a thousand screws I would think differently and employ the method you mentioned!

[@RocketSailing]

Hoping for a new update and episode soon!

[@nigellee1856]

interesting, where do you get the thread rolling dies not seen one that size before.

[@JimbobPalmer]

From floydautomatic.co.uk and the dies are by Harold Habegger, they go down even smaller and I will be using them for my M0.4 threads too!

[@nigellee1856]

@@JimbobPalmer thanks for this it turned out to be what I was looking for.

[@teegeesg]

Very nice, I didn't know those roller dies existed either. What size was the one you used? From looking at the catalog, this is likely priced for professional use only :)

[@teegeesg]

Oh, it says right in the video.. nvm!

[@kevinrblodgett]

What is the name of the turning tool and holder please? It looks very rigid

[@JimbobPalmer]

I use Applitec turning tools, you can find them on floydautomatic.co.uk

[@simonkangiser6183]

Where did you purchase the roller die?

[@JimbobPalmer]

I purchased them from floydautomatic.co.uk and the dies are by Harold Habegger
