Earlier this month, a student of ours, Brad Taylor from Toronto Canada, was interviewed by Eternal Tools and published on their blog. Eternal Tools is a tool manufacture based in UK and they have some interesting tools for the watchmaking industry. We encourage you to go over to the Eternal Tools blogpage and have a look.

Timing and Examinations

Today in the workshops some students are taking their escapement examinations, which involves tiny adjustments. The goal is to achieve the most efficient, but safe transfer of energy in the escapement.

In this large model we can see the jewels which can be adjusted, in the actual pallet fork the jewels are held by shellac. the entire fork is heated on a plate and adjusted very precisely. Adjusting the escapement can take multiple attempts making this a sometimes challenging process.

In the other class students have been introduced to the timing machines and dynamic poising.

After spending a long time with hairsprings sometimes micromechanics work is a good way to change things up. Here's Brad on the Schaublin 102.

As well we have a new bench testee getting introduced to some of the basics n the workshop.

Oscillator Theory

For the last few weeks, the students in Workshop 1 have been going through the balance & hairspring module of the course. It involves a lot of practice in manipulating hairsprings, which can be painstakingly frustrating but at the same time extremely fascinating, and satisfying once you can do it. In the picture below, Henrik is giving the students a theory lesson of isochronism, using this brilliant oscillating model for demonstration which helps a lot in understanding the theory.

Pallet Forks & Hairsprings

Today workshop one is continuing their work with balances - flattening hairsprings, pinning collets, reaming collets and other related work.

In workshop 2 the students are working on adjusting the jewels in the pallet fork. After learning the theory they continue to the bench and practice adjusting the drop and total lock of the Swiss lever ecapement. The adjustments are very precise and important for good function.
