This week we are doing a drafting module in class.  The old Chicago School of Watchmaking program has a 'drawing of the Swiss lever escapement' chapter so we are following the steps outline in that program to complete a reproduction of a standard Swiss lever.  In class I have been working with traditional drafting equipment: pencil, compass, square, protractor, etc. 

However I also have been working with CAD software which makes the process much more accurate and much cleaner.  See the pictures below.

Here is the CAD layout for the escape wheel
