| Kai shows the students how to draw gear teeth on Inventor |
This week students learned how to make gears in Inventor thanks to Henrik`s brother Kai, who was kind enough to teach them how to draw. It very useful to the students since they will be designing their own school watches in the 2nd year.

Henrik also gave a bonus lesson on another finishing technique used for making the sun-ray pattern last Sunday. Using a special setup on the 70 lathe with the milling attachment they were able to produce perfectly centered sun-ray patterns.

What often happens in watchmaking is that watchmakers drop tiny components all the time. Theren dropped his balance staff and everyone helped in looking for it. With the team effort, Theren was able to retrieve his lost balance staff.

This past Saturday Henrik took the students to a flea market in Fribourg called the Retro Technica. It was filled with cool machining tools, radios, vintage video games and many many watchmaking tools, including collets, drills, taps, lathes, and many other tools. It is a great place to get bargain deals on used tools for watchmakers.

A man can fail many times, but he isn't a failure until he begins to blame somebody else.
