Here we observe an interesting event. On a ETA 7750 which at very low amplitude the escapement greatly miss-locking. The escape wheel tooth can be seen falling directly on the impulse plane of the jewel. Although as the amplitude rises, the teeth can be seen sliding up to the locking face from the impulse face, until it very quickly falls directly onto the locking face, no longer miss-locking. Interesting to see.
On other news, a lot of students have been taking exams this week. Gui and Caio both took their winding stem exam, and Nick took his first exam. Nick took his male and female exam, hand filing two brass pieces.
Here we can see Nick now learning his way around the lathe.
Onto Chris, been forging some metal. Melting his tin to make a black polishing plate.
Jaewon started to take apart his Valjoux 23, finding some interning reparations. The pusher lever having been welded together. Interesting technique.
That’s it for this week. Until next time!
