Learning new things

 Henrik started his students off with the chronograph course. Running them through theoretical concepts of old to new chronographs.

Educational movement 

In the meanwhile, Michael’s students got a thorough lesson on the jig-borer. They were introduced to the Hauser 2A3 jig borer. Exercises included centering the work piece with the microscope, scribing a square and a circle, as well as drilling holes with different diameters and depths.

This week Greg also made some headway on his own project. He managed to finish turning and polishing a pinion, then he riveted the pinion to a brass he made.

That’s it’s for this week.

Until next time!

3D Printing

 

Week 2

The globe turns and another year begins anew. In the lobby of the school, KHWCC has hung a map of the globe with pins to mark where all of the students have come from.

Another new feature in this new year: the workshop has gained a 3D printer. After the initial setup and stock test prints, Louis and Dunny from Workshop B used this tool of additive manufacturing to make custom movement holders.

STUDENT HIGHLIGHTS

Workshop B

Students:
    Craig, Dunham, Ivan, Louis, Sheikh, Varun

    Craig learned how to cut the leaves for a pinion, and then polish them to mirror perfection using a wooden wheel and hand finishing.

 

 Louis continued his restoration of a mid-19th century marine chronometer by making a new ratchet wheel and spring, modifying a click to fit, and fitting a new fusée chain. To manufacture the ratchet wheel, he first had to make a custom fly cutter, and the fusée chain needed to be shortened and the direction of the barrel hook flipped.

Hope to see you again next week!

Out with a bang

 Last week!

The year comes to a close and the students get ready to fly back home. With the last few days before the break we are all tying loose ends and finishing up any bits of work.

Art finished his hour wheel exam, and with Nine, they will be moving on to start their technician course next year! Craig started work on the center wheel for a 6498. This week he completed machining, filling and bevelling the wheel.

Almost finished product 

On the penultimate day we had a trip to visit a horologists in Sainte-Croix. We first had a tour of the micro-engineers at Cap14 then we got to explore the manufacturing facility of Reugue at mec-art. We were given the opportunity to listen to some of their legendary music pieces. 

Stay tuned for a more in depth post coming up!

Tour of Cap14 micro engineering manufacturers 

For lunch we shared several kilograms of Fondue. The hardest part of the week was leaving no cheese behind. All the students were given matching K&H bennies for the winter.

The last day was spent as every last day in K&H is spent… cleaning! From morning to evening every student does his part to leave no surface of the workshop unscrubbed. Every shelf is emptied and wiped, all machines cleaned and oiled, fridge is cleared out every corner is cleaned with the attention of a watchmaker. 

Final touches 

And that’s it for this year!

Have a lovely Christmas and special new years!!!

Until next time.

Library

Week 49

As the year begins to wind down and winter break approaches, the school took a break from work to pay a visit to Editions Simonin, an extensive library of horological books, tools, and workpieces.

Madame Simonin welcomes the students

 

Art examines some technical drawings

Several of the students took the opportunity to purchase some reference books for themselves, while the school administration also added to the KHWCC library.

Some of the spoils

Back at the school, Michael showed Bernd, Cesar, Joan, and Loius Lu how to use some of the heavier machines in the workshop - an industrial jigsaw, grinder, and bandsaw - to cut blocks out of 8mm plate brass.

Thank you for reading!

Hope to see you again next week!

Pantographing

 The new students are now wading into deeper waters and learning how to operate new machinery. This week Michael showed them how to use the pantograph and how to mend damaged cables. Bernd was quick grasp its concepts and start decorating his tools.

Craig completed his first Geneva stripes finishing, on his pallet fork holder. In the same week he also achieved a near perfect score on his hour wheel exam!

Behold….. a very fine hour wheel

And let’s not forget, Thanks Giving! The students brought in home cooked meals traditionally made from where they are from. Spanish, Hong Kong, Indian, American, Swiss too. With the most complimented dish being Craig’s chicken pot pie.

Snow!

 

Week 47

Winter has officially arrived in Le Locle, heralded by a large amount of snow. But whether arriving by car, bus, or trudging in on foot, the students continue their work... as well as some fun.

We also had a new bench tester braving the weather: Kyle from the Philippines.

STUDENT HIGHLIGHTS

Workshop A

Students:
    Art, Bernd, Cesar, Joan, Louis Lu, Mun, Nine

    This week Bernd and Cesar passed their first exam testing their skills at filing. Louis Lu continued his practice, seeking perfection.

Joan drilled the first holes for his press-fit plate.

Art made his first balance staff, but succumbed to the curse of all watchmakers and lost it soon after grading. RIP tiny parts.

Update: He found it!

Workshop B

Students:
    Craig, Dunham, Ivan, Louis, Sheikh, Varun 

 

    This week Henrik gathered the workshop together for a demonstration of how to create Geneva Stripe patterns for surface finish. Following the demonstration, Louis and Varun tried their hands at recreating the pattern, Varun in brass and Louis in brass and german silver.

 

Ivan tries his hand at creating some stripes.

Craig also made his first balance staff this week, turned to the dimensions for the 6498 movement.

Hope to see you again next week!

Learning the ropes

Bench test! Sully from New York, came to spend 5 days in Le Locle to join us for his bench test.

This is the second week for the new students, exciting and yet daunting with the prospects of the meticulous work in the months to come. After having learnt the very basics with filling and sawing, they have now moved on to learning how to operate the basic machinery such as the drill and lathe. They have now started to go through the processes of tapping and threading, skills which will be used when producing their own watchmaking tools.
