Week 39
And with a sudden shift in weather, the days have gone from warm and sunny to cold, rainy, and dreary. Everyone in the school felt it too, and sometimes there are just weeks where you try your best, but glass breaks, polishing scratches, and hairsprings don't bend right. Still we persist.
The best weather all week and still no sun
STUDENT HIGHLIGHTS
Workshop A
Students:
Art, Bernd, Cesar, Joan, Louis Lu, Mun, Nine
In spite of the melancholic weather, Cesar made some nice progress on his set of pivot gauges, completing several with sharp shoulders and smooth domes.

Workshop B
Students:
Christiaan, Craig, Gary, Jaewon, Philippe, Sense
Christiaan, Gary, and Philippe were introduced to the watchmaker's lathe, a small 8mm version used for hand-turning small components. They now work through a set of practice pieces, getting used to finding the right position of the graver and the feel of a smooth cut.
Craig joined Art in shaping of the outer coils of the hairspring. Attaching the stud via a brass pin, gently adjusting the outer coil so that the curve always sits in the middle of the two regulating pins regardless of their position, adding a double-bend so that the collet aligns centered with the pivot jewel, and tweaking everything so that the coil sits flat - this is the final step of constructing the balance. Following this, only adjustments to poise and timing remain.
