Revised Pallet Fork for Watch Escapement
I provide an adjusted Pallet Fork for Karl Lee's astonishing Watch Escapement Desk Toy.
I strongly recommend this fun project. It must have taken Karl many tens, if not hundreds of hours to design so you may like to "Tip Designer" to show your appreciation as I have done.
Please be warned that Karl's files are not all in the best orientation for printing so you will need to rotate them to avoid the need for a lot of support. The Winding Key and the Winding Stem are the only parts that do require support.
Initially I could not get my escapement to work. I decided that the reason was that the prongs of the Pallet Fork were at too flat an angle where they touch the Escape Wheel, causing it to bind. I have therefore increased the angles as per my attached file and my escapement now works.
