Fly fan decoration; time train clutch - March
Most of the month of March was taken up with evaluation and modifications
to the major redesign change of the movement (see prior page). However B. was able to make
the final shape and decorative perforations for the remontoire fly fans. The final shape
was taken from my submission made in June 2008. The perforations will be a calligraphic
letter 'B' for the firm's name. What you see here are paper mockup
blades. The cutouts in brass will be done later.
Below are tooth count calculation drawings for the part of the remaining
three trains that will reside within the main plates.
The first photo below depicts a few of the wheel blanks from the photo
above as well as well as other finished wheels that will reside within the main frames.
The remaining photos show the time train clutch. This device is what will allow the user
to de-couple the time train from the celestial train and thus allow the high speed
demonstration of that train. Notice the embellishments B. adds to the locking nuts as well
as the creating five finials for what most would have left as plain cylinders. The last
photo shows the clutch installed into the movement in April.
