Wheel of fortune

It's Cartman!

Last week the students started learning about the barrel.  They continued this week on correcting barrel flatness and concentricity and also learned how to lubricate the mainspring.

After learning about the barrel, Henrik proceeded to teach the students how to check the conditions of the gear train, especially bending the wheels back to flatness.

Eddie continued to work on the winding stem on the 8mm lathe.  He learned how to make threads and also how to harden and temper.

Nicolas started with the Schaublin 70 this week, making male cones and female cones.  He finished his press fit plate by utilizing the skills he has learned these past 2 weeks.

Winter approaches

Disassembled Incablocs
This week the students started to assemble and disassemble incablocs.  Incablocs are the shock absorbers in watch movements that prevent balance staff pivots from breaking.  They are extremely small and delicate, therefore it is a good exercise for the students to improve their manipulation with tweezers.

Henrik also started teaching the students how to oil watch movements, beginning with the winding and setting mechanism of the 6498 and 7001.  

Eddie has begun turning slots in preparation for the winding stem.

Meanwhile, Nicolas started to learn about the machines, starting first with the drilling machine and now this week he continued with the milling machine.

So far Le Locle has been kind to us with the weather, however, as news has it, we are expecting approximately a 20 degree drop in the next 3 days.

Second year begins

New coats
This week Simone, Tomas, and Theren officially started the second year of their program.  They were given fancy new white coats!  They started the 2nd year by working on the 6498.  Practicing the correct ways to assemble and disassemble the movements.

The students needed to make their own customized tools.  They decided to cooperate and focus their energy into making their tools together as one.  They were able to finish the project in a fast and effective manner.

What they can do

On Wednesday we had a guest from NovoWatch to introduce their products and services.  NovoWatch is a small local company that offers services such as: Finishing, decorating, and part-making (all parts of the watch).
Everyone having a good time

The school had it's second fondue party to welcome the 2 new students, Eddie and Nicolas.  It is their first time having cheese fondue, and they loved it.  Although it was the other students' second time, they really enjoyed it also.

Full house

Nicolas filing away
Good news everyone! we've got our newest member and his name is Nicolaaaaas (with just one A).  This means that the school has filled up its last spot for the 2015-2017 fullskill course.  We are very excited to have him here and he has shown that he is very very excited to be here.
Our plating machine

The students watching the magic happen

Henrik worked on a project last week utilizing the plating machine to restore hands for a GP alarm watch.  He took this chance to show the students how to use the electric plating machine that we have in the school.  We are able to plate with rhodium, palladium, nickel, rose gold  and yellow gold on all non-ferrous metals.
Beautifully finished tripod from Eddie

Eddie finished his polishing tripod and it looks excellent!  He was able to decorate the bevels using the sand blasting machine.  The picture above should be self-explanatory.

Theren worked all week on a restoration project regarding making a Geneva stopwork mechanism for an old Patek Philippe watch.  After facing multiple obstacles, he was eventually able to complete the parts to satisfaction.
