WEEK 80
Pierre Aubert
Origin :Toulouse, France.
Age : 24
Watchmaking class: Fullskill
Current mood: I dedicated most of the week to drill the remaining holes for my bridges: escape wheel, crown wheel, ratchet, second gear train bridge screw and a second pin for the balance bridge. For the gear train bridge screw I had to file the bridge equally in order to be able to measure the available space for the screw. I then had to chose an appropriate location for it, it will be asymmetric and give a look that I like :) One side has a screw at the bottom, a pin at top while the other has a screw at the top and the pin at the bottom. It’s getting cold here, have a good weekend everyone!
Name: Markus McDonald.
Origin: Stockholm, Sweden.
Course: 2 years full skill course.
Current mode: This week we had the chronograph course this was nice as it allowed me to focus on personal work specially the pivot gauges.
For the pivot gauges I adopted a production style where for one step at a time I made several pieces.
This started by getting all the pieces together and checking overall quality of the body, next in the Bench lathe I would divide the body into two sections. Then checking the quality and getting the bodies as good as possible. Next degussit Stone and finally the burnishing.
This method worked out very well as I was able to make each step as good as possible reducing chances of error.
In conclusion this went very well and I was able to make a couple of pivot gauges a long with getting 85% of the body done.

Current Mood: This is the individual week for us since there is a chronograph course week going on. Have been doing my pivot gauges coursework for the week and it is getting there slow and steady. The new technician course student is here and I will be starting my technician course with him. Can’t wait to start the new journey.

WORDS:
Very exciting week
indeed! Stefano and James came back for a more advanced subject. This time to
study the vintage chronograph and its restoration and repair in depth, we
covered a lot! Apart from learning the classical chronograph rules and
adjustment points, analyzing the mechanism etc. they both even made two return
to zero hammers each from scratch, one fully adjusted with some finish, and a
spare one for later use for a real restoration project. Also Willy from
Singapore arrived for the technician course, and Markus had his birthday. A
very efficient and smooth week! Also another Henrik’s Minutes short video was
published about screwdrivers by The Naked Watchmaker; https://www.thenakedwatchmaker.com/blog/2020/7/28/henriks-minutes-tweezers-the-watchmakers-first-tool-b2mgd?fbclid=IwAR3VAzr8WaluG4s0eWMXiSMRC4VUmsWvz7uJq5HoHm9jg0b_xKxIjCFeyys Thank you! Have a
great weekend everyone!
