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.

At the end of the micromechanics course, Theren also did an exercise, making a missing yoke in an unknown movement.
