Storm clouds gather

 Rainy week here in Le Locle, dark skies and thunders fill our evenings. Signs of the end of summer. Soon the days will get shorter and the nights colder. In our workshop Caio and Gui have started work on the hour wheel. A fun project were we learn how to cut teeth on the lathe using the milling attachment and teeth cutters. The process is not too long, most the time is concentrated on centering the teeth cutters with a microscope.

Caio’s first hour wheel.

Joan took his hairspring exam this week and successfully passed it, congratulations!

Nick over here is getting a lesson on the Agathon. A grinding machine used to sharper hard metal gravers.

While Chris, Gary, Phillip and Jaewon are still going through the theory of the escapement, the beating heart of the watch. Taking their time to learn all the different methods to restore and fix a damaged pallet fork. Here Gary is doing a guard pin replacement. A rare skill, where nowadays most would just get a new pallet fork.

Here we see a neat little tool made by Chris. Is a brass anvil to be used with the Horia pusher for guard pin replacement.

That’s it for this week!

Until next time.

Time to learn

 The students at workshop two have started the escapement course. A lengthy course which teaches the full theory of how the Swiss lever works and why it works. Along with the theory we learn how to restore and diagnose an escapement, as well as adjust the escapement.

David the new student is here for his second week. Still working on filing, the basis of all watchmaking.

Many of us have also taken this week to melt our tin to make polishing plates. We melt the tin by a touch then pour the molten tin into a mold. This is then turned on the lathe to mark a smooth surface. 

Until next time!

We’re back baby

Everyone is back from the summer break, some never left. But we go straight into it, Michael is teaching us all some new decoration techniques. We’re all learning polishing counter sinks and bevels, different nailing methods on ratchet wheels, as well as Geneva stripes and frosting. Everyone is going out and trying their own individual way. Let’s see what they’ve done!

Starting off strong with a ratchet wheels by Jaewon. Using the milling attachment with a brass bar attached with some diamond paste. Choosing the speed for the lathe and the milling attachment will drastically affect the final look. Then afterwards he heated the wheel to a straw yellow.

Here is a practice piece for the counter sink and bevel polishing, with the surface frosted. After which it was plated with white rhodium.

Let’s follow Guillerme as he decorates this movement. Here setting it up for Geneva stripes 

Lovely done Geneva stripes. Came out look very nice.

 Finally he finished it off by electro plating it in white rhodium.

Trying some double snailing, a classic finish. How does it compare to single snailing?

We will have more next week! 

Until then
