WEEK 200!

  WEEK 200

Team A

Origin: Sweden, The Philippines & Taiwan
Name: Daniel, Miguel, & David
Watchmaking class: Fullskill
Current mood:

This week David focused on making his brass anvil, Daniel focused on remaking and fine tuning his hand vise and is starting to conceptualize his school watch project and I focused on making my steel angular rule and brass truing guide.- Miguel


Team B

Origin: Japan/Switzerland & Canada
Name: Tetsu & Dean
Watchmaking class: Fullskill 
Current mood:

This week, (30 January ~ 03 February) Dean & Tetsu continued woking on the barrels, the winding & setting mechanisms, and the gear trains of the mandatory 7 movements. 
There are a lot to check and adjust.
They are at the stage to see, compare, think, adjust and check; which takes a long time. Even with Henrik‘s instructions, it is still not easy to get things right.
Hopefully, after gaining much experience, they will be able to know what should be done when you see parts and components.
In between times, Dean was working on his watches for repair points. So far the serviced watches were showing good results.
Tetsu ventured into uncharted territory this year, and after a few weeks of practice, he was slowly getting used to working with tweezers and screwdrivers.
Still a long way to go, but time is running!Speaking of time, it is noticeable now that the daytime is getting longer. It is not dark anymore when school starts and it is still light when it finishes. Having said that, some amount of snow falls every day even there are some warm-ish days, so the winter is not over yet.
Wish you all a nice weekend! Dean & Tetsu


Team C

Origin: Switzerland, Norway & USA
Name: Renato, David, Francesco, Åsmund & Robert
Watchmaking class: Fullskill 
Current mood:

David and I covered the final topics on watch timing this week. We also practiced dynamic poising and basically getting a proper timing in general by tweaking all factors  involved. Interesting to see how small increments of changes need to be done in the end for fine tuning and what affects what. All work above was done while doing the practice exams for hairspring. Looks like we'll be ready for the final exam next week!

Name: Daniel, Miguel, & David
Watchmaking class: Fullskill
Current mood:

This week we focused on making our tools.Daniel practiced using the milling machine and lathe milling attachment to make his pointed hand vice.David used the milling machine to prepare his polishing tripod and his brass anvil.And I focused on making my brass wheel truing guide, my steel angular rule and finishing the base of my balance bridge holder.- Miguel

Team B

Origin: Japan/Switzerland & Canada
Name: Tetsu & Dean
Watchmaking class: Fullskill 
Current mood:

This week, Henrik introduced Tetsu and Dean to gear train and jeweling.  This included making adjustments to the barrel to ensure negative end shake removed.  Also, the straightening of wheels was covered to ensure flatness and concentricity.  Jeweling was covered with how to use the Horia tool to remove, install, and adjust their heights.  In addition to this, wheel end shake, clearance, division, and side shake was introduced.  After the lesson, Tetsu and Dean applied what they learned to their seven school movements to then show their work to Henrik for review and corrections, if necessary.  It’s nice to be learning this skills while assembling and adjusting these movements.Have a great weekend everyone!Tetsu and Dean

Name: Renato, David, Francesco, Åsmund & Robert
Watchmaking class: Fullskill 
Current mood:


Hello everyone, this week has been really busy. 
I made a special pallet fork holder entirely machined made.
It was a really nice exercise that helped to keep my micro-mechanics skills current, I turned and milled in the lathe, bored in the jig-borer, milled the platform in the Aciera, drilled and tapped.
Then I finished it with straight-graining,
 frosting and plated it.
Then I kept on going with the technician program, this week I adjusted the division between the pallet fork and the escape wheel.
See you next week,
Francesco.

COLD!

 WEEK 198

Team A

Origin: Sweden, The Philippines & Taiwan
Name: Daniel, Miguel, & David
Watchmaking class: Fullskill
Current mood:

This week we learned how to use the milling attachment for the lathe, we used the milling machine to practice the brass anvil and make our polishing tripod.Me and David made the balance bridge holder and Daniel started working on his pointed nose hand vise.I also made a practice piece with the different divisions of the milling attachment on a single brass bar.

-Miguel


Team B

Origin: Japan/Switzerland & Canada
Name: Tetsu & Dean
Watchmaking class: Fullskill 
Current mood:

This week, (16~20 January) Dean & Tetsu continued their current tasks: Disassembly, cleaning, oiling, and assembly of Incabloc settings, in addition to the winding & setting mechanisms of the mandatory seven movements.

Dean worked on refreshing his skills, which he gained from previous years, by applying what he learned in school so far to strengthen his abilities. He also registered some of his watches for repair points, and has already almost finished one of them.

It was a bit different for Tetsu as he has no previous experience. Everything he learns this year would be entirely new. He took his time to first get accustomed to handling tweezers and screwdrivers. Then, he tried to understand how to work on the watch components. It would not be easy at the beginning, but he needs to go through step by step. There will be no shortcuts for this one.

On Thursday, Henrik gave them a lecture, explaining the construction of different types of barrels and how to service those, and the guys have already started this new task.

No time to stop!

We wish you all a nice weekend! 

Dean & Tetsu



Team C

Origin: Switzerland, Norway & USA
Name: Renato, David, Francesco, Åsmund & Robert
Watchmaking class: Fullskill 
Current mood:

Overview: This week was an introduction to the pallet fork and balance wheel of the Swiss lever escapement. We worked on our school movements to find and correct any introduced faults on those new parts of our studies. (Pallet stones in reversed positions, the odd little things like that...)
In addition, we each worked on a different version of a tool that is used to hold a pallet fork on a heater so shellac could be applied to secure the pallet stones in the pallet.
Local news: It's hovering around 0°C day and night, the snow we got should last for 4 or 5 more days.

-Robert


David and I reached the final steps before the hairspring exam: studding up the hairspring on the balance bridge, forming the regulating curve and double bend, centering and flattening everything nicely in all directions. Very interesting to slowly get the feel for the hairspring manipulations and which tools to use for each operation. Next and last step before the exam will be the timing, beginning of next week. Also we'll start the practice exams then. Quite a demanding exam with very many process steps!
