Remontoire fly fan fabrication-rough out, May 2008

Initial work begins on the remontoire fly fan assemblies. These components are a major feature of the clock movement so great attention is paid to this subsystem.  Notice how a major safety component like the ratchet wheel, 2nd photo, receives four screws in the collet.

  Below are the remontoire fans in their initial rough out condition. Compare this to the final product in the next month as well as the original mockup made in wood in early 2006.    

Below is a shot of the process for slitting the screw heads. All screws are custom made for the clock. No off the shelf parts. These will later be heat blued to a bright color.
