GREEN!

 WEEK 163

Team A

Origin: Thailand & USA, 

Name: A, Kate, David & Leilani

Watchmaking class: Technician

Current mood: 

This week all the technicians continue with the hairsprings. The hairspring is one of the most complicated lesson. We use many tools and it is necessary to checks it with the theory. We have spent this week learning the theory and practicing. We are focusing on hairspring flatness and its concentric to the balance staff and wheel. Getting things flat and round at the collet are the first steps to do before putting the wheel into the watch to check the timing.

Team B

Origin: Japan/Switzerland & Canada

Name: Tetsu & Dean

Watchmaking class: Fullskill 

Current mood:

This week, (16~20 May) Dean & Tetsu had an intensive one and both were pretty much exhausted even before the end of the week.

Dean was working on the Brass Anvil and Tetsu was on the main bodies of the Pointed Nose Hand Vise. Both tools require significant amount of milling, drilling, boring, and hand sawing & filing. As predicted before, those were big challenges and real tests of patience.

Dean and Tetsu took completely different approaches to begin with; one was not afraid of the risks and „learning by doing“ style, while the other was „think twice before starting“ way.

Somehow, our work strategies were changing as the time went by. The risky one became a bit more cautious; started making plans and working step-by-step, and the careful one became slightly braver; wanted to try new techniques and see how it goes. In the end, both of us came to the final stages of finishing their tools, and will soon be getting ready to hand the pieces over to Henrik to be graded. 

Now we are ready to enjoy the weekend.

Hope you all have a great weekend, too!

Hello, 

This week i finished up two screw heads for my polishing tripod. It’s for adjusting the height so you will be able to make the object you are polishing flat to the tinplate. 

So many great designs were already used by other students and I wanted to have something unique, since this is a tool I will be using a lot in the future I want something that is pleasant to look at and something out of the ordinary. After a lot of thinking and wondering I were left with this design, I must admit I got very satisfied 😃

All work were done in the shaublin 102. This was very fun since I had to figure out a way to work on all the faces and also develop my own cutter which was small enough to not get caught inside the circle. 

I love the 102, it surprises me what this machine is capable of doing! 

Great weather also arrived, it started okay in the beginning of the week and as the week went by it only got hotter and hotter with Friday being the hottest with 27+ Celsius!! 

Other than that; Fransesco bought two new tools, one vertical micrometer for me and one rack and pinion tool for him and David bought a new 8mm lathe. So we spent the morning disassembling and cleaning the tools for rust and dirt and they came out great, almost like new! David’s lathe where made of German silver and after cleaning it looked like brand new! Great find for a good price 

Fransesco were quick to check if the horotec attachment would fit and figured they didn’t, so he started to make adapters. 

The dial gauge I got only measures 100’s so now I’m looking for a digital micrometer to modernize the old tool and be able to measure 1000’s. Already planing to make an adapter in German silver to mount the new micrometer on the stand, so stay tuned! 

Renato just did the hour wheel exam on the hottest day of the week and I think it went very well! 

Have a great weekend everyone!

More work on perfecting winding stems. Trying to keep them straight during the heat-treatment process, refreshening the surface of the T-rest so the gravers will slide smoothly back and forth when cutting the length of various sections...getting closer and closer to everything coming into place for the finish of this challenging task.

Looking forward to next week, Robert.

STEP 1: FANCY SCREWS! (ÅSMUND)

Asmund machined these very cool looking screws for one of his tools!

STEP 2: WHEELS! (RENATO)

Renato practiced making hour wheels in the Schaublin 70 lathe.

STEP 3: HAIRSPRING ADJUSTMENTS! (TECHNICIANS)

David working on tweaking a hairspring!

STEP 4: GREEN! (EVERYONE)

It got really vividly green this week!

STEP 5: VINTAGE WATCHES! (A)

A submitted another interesting vintage watch that he will overhaul during the course!

STEP 6: HAIRSPRINGS! (TECHNICIANS)

Some valid advice from an old NIVAROX plate for the students to find solutions to their hairspring problems!

STEP 7: MILLING! (RENATO)

Renato busy milling on the Schaublin 102! He needed a special washer with an angle incorporated into it that cannot be purchased commercially so the only way is to make it yourself! 

STEP 8: BOOKS! (KHWCC LIBRARY)

Since the technicians are on the subject of balance and hairspring, they got to see this old book and realized the existence of different types of oscillators and their features!

STEP 9: WINDING STEMS! (ROBERT)

Comparing a blue-tempered stem to hands on a vintage Gallet, partially made winding stem by Robert after the tempering!

STEP 10: T-REST! (ROBERT)

After heavy use Robert refreshed his t-rest!

STEP 11: TEMPERING! (ROBERT)

Robert tempering one of his winding stems!

STEP 12: TOOLS! (ÅSMUND)

Asmund found this really nice stand that he will make an adaptor for so he can install a modern micrometer on it!

HENRIK's WORDS:

 

This week we got very hot, like summer in Le Locle, at its peak, it got as high as 27 degrees Celsius! Asmund finished two very cool looking screws for one of his tools!! The technicians learned how to deal with hairsprings, first on alarm clock size hairsprings and then on pocket watch size, they will continue later with smaller hairsprings. Renato practiced making wheels and ended the week with taking the hour wheel exam. Francesco and David were busy turning pivots, Dean and Tetsu continued machining tools! It was a very enjoyable week! have a great weekend everyone!
