WEEK 138

Watchmaking class: Technician & Fullskill
Current mood: Another busy and lots of drawing and technical week for me. Learned so much about the Swiss lever escapement and how to design a watch. There are a lot of perspective and information how to design a watch and what are the necessary steps to start with so you don’t corner yourself during the designing process. Through designing parts one would have to also know of how to produce the parts, is there enough material or how thick the parts should be. It was a real challenge and I am so far enjoying the whole journey myself.

Current mood: Made the Maltese cross prototype from brass. Started with a 20x drawing via profile projector, then I did the calculations according to the theory. Afterwards I made a cardboard model. The model did not work optimally, so I adjusted the values based on the 20x projector drawing. The model was great though to understand the function. Then I spent some time and created several versions of carbide cutters to bore to screw head recess until I figured it out. The cross came out fine, only small adjustments needed now. Also started making a screw for it since it's a somewhat exotic size. Looking forward to make the real steel cross next week! Renato
This week I worked on winding stems. I have continued working on them in order to start my practice exams for them. David

Hello everyone,
Last weekend I went to Zürich and visited the Breguet museum which was really good, the museum guide were very nice and knowledgeable. Would recommend anyone to go there and see the historical watches they got there.
This week I’ve been busy in the milling machine and jig borer, finished the brass anvil and the polishing tripod. Also did the threads on the tripod, so now I only need to finish the screw heads before I can start to use it. Already made supports for larger parts other than the screws. Head over to our school Instagram to see the support and the results for black polishing 😊👍🏻
Have a great weekend.

Hello everyone, this week has been a bit tough for me because of health problems.
I almost finished the brass anvil tool, I filed the triangle to the right dimensions.
See you next week,
Francesco
Started off this week by doing minor steps to finish some square-head screws from round brass bar. This was a process that used a lathe (and a milling attachment for it) to reduce the brass bar to the proper diameter for the thread, then used the milling attachment to cut each flat surface into the bar.
I got started on a new project, too. It is one of the tools we need to make, with a little added modification. Mr. Korpela requested a modified drawing so when he grades our work, he knows what dimensions we used to make the modifications, and that they will meet the tolerances for the tool. The drawing was made, and machining has been started. Progress!

HENRIK's WORDS:
Real winter has arrived! We got some snow this Friday and forecasting more over the weekend and due to the expected lower temperature it may stick around for some time hopefully! not much new this week, Renato continued on his Maltese cross for his stop work and made a brass prototype and screw for it, David resumed the making of winding stems, Francesco, Robert and Asmund continued with tool making and Michael finalized his design of the Swiss lever escapement. We also got notified that the F.P. JOURNE Young Talent Competition for 2022 is now open for entries! It was a pleasant week! Have a great weekend everyone!
