NEW ARRIVALS!

 WEEK 210

Team A

Origin: Sweden, The Philippines & Taiwan

Name: Daniel, Miguel, & David

Watchmaking class: Fullskill

Current mood:

This week we learned heat treatment and how to make a steel winding stem from turning it down from a solid bar to hardening and tempering.

Team B

Origin: Japan/Switzerland & Canada

Name: Tetsu & Dean

Watchmaking class: Fullskill 

Current mood:

Tetsu and Dean advanced their escapement knowledge by understanding the relationship between the pallet fork and the roller.  Henrik introduced Tetsu and Dean to the function and safety controls of the Swiss lever escapement, which comprise the lateral clearance between the roller jewel & notch, control of horn clearance, and control of guard pin clearance.  The role of the banking pins was also covered.  Henrik followed up by providing a lesson on the angle of draw, an important feature of the Swiss lever escapement in the context of security to ensure the pallet fork remains locked notwithstanding the presence of shocks associated to the wearing of wristwatches.  This knowledge of the angle of draw was the segue to the adjustment of the total lock, which is the sum total of the “drop” and “run to the banking.”  To adjust the total lock, Henrik showed Tetsu and Dean how to use the escapement metre to depth the pallet stones.

With what they’ve learned from this lesson, Tetsu and Dean went to work on their seven movements, ensuring the escapements were checked and adjusted as required.

Have a great weekend everyone!

Team C

Origin: Italy, Norway & USA

Name: Francesco, Åsmund & Robert

Watchmaking class: Fullskill 

Current mood:

Balance Hairsprings.

This week we continued working on the small hairsprings that are involved in the back-and-forth rotational movement of the circular balance wheel in a watch.

"Flattening" of the hairspring, so it isn't tilted. Then making sure the coils have the same space between them, which means the weight of the hairspring is as evenly distributed around the balance staff as possible, and so no coils will touch each other as the spring expands and contracts during it's winding and unwinding.

Then the studding of the hairspring, and setting the regulating curve in it. It is a great feeling to have adjusted the regulating curve so the spring has room to vibrate between the regulating pins of the regulator as it is moved along the arc of the regulating curve. Finished with the first spring studding, now on to the next spring!

Team D

Origin: Finland

Name: Xinying

Watchmaking class: Technician

Current mood:

I am starting to finish seven practice movement and managed to do two in this week. It is nice to see the progress and handing finished movements back to teacher.

Team E

Origin: Serbia

Name: Amer

Watchmaking class: Upgraded Technician

Current mood:

This week was very fun and interesting, i learned lots of new stuff and gained knowledge about new things.

I learned how to use a drill and how to make a hole and make a thread. I also started learning how to work on a lathe.

I made a few tools that i will need in the future and i am quite happy how they turned out.

Team F

Origin: USA

Name: Dunham

Watchmaking class: Upgraded Technician

Current mood: 

This week I learned how to make simple brass watchmaking tools by filing them within various tolerances. Additionally I learned how to use the drilling machine as well as the lathe. Using these tools I now have the necessary skills required to make a balance bridge holder which I plan to finish next week.

STEP 1: NEW ARRIVALS! (DUNHAM & AMER)

Amer busy filing!

Dunham busy preparing the lathe for turning!

STEP 2: TOOL MAKING! (DUNHAM)

Dunham almost completed his first tool!

STEP 3: PROTECTION RING! (DANIEL, DAVID & MIGUEL)

After quenching the rings were tempered!

In preparation of making complete winding stems Daniel, David and Miguel make protection rings for when they will file the square!

STEP 4: WINDING STEM BASKET FOR QUENCHING! (DANIEL, DAVID & MIGUEL)

Basket to protect the winding stems during quenching!

STEP 5: WINDING STEMS! (DANIEL, DAVID & MIGUEL)

Winding stems and protection rings after heat treatment.

STEP 6: WATCHES! (ÅSMUND)

Asmund submitted some nice vintage watches that he will soon overhaul!

HENRIK's WORDS:

 

 

We got some heavy snow fall during one of the Easter days and it has been rather cold this week as well! We also got two new students! Amer from Serbia and Dunny from Texas, USA! Xin Continued servicing and repairing complete movements! Francesco, Robert and Asmund finished vibrating hairsprings and learn how to pin them up to the stud, forming the regulating curves and making double bends! Dean and Tetsu continued on the escapements checking notch, guard pin and horn clearance as well as adjusting the pallets to make them functional with minimal total locks while still being safe!  Due to Easter the week was one day short and became rather busy! Have a nice weekend everyone!
