Full scale mockup page 1
Beginning in January of 2006 I started to confer with the fabricator on the final
design for the clock. I had already done two years of prior design work so there was a lot
of ground work already covered. Between January and July an intense collaboration resulted
in the creation of this mockup. The result is both a testament to the extraordinary
talents of the fabricator as well as the ability for the both of us to convey our ideas to
congeal into a mutual design. This mockup as well as all of the concept drawings were done
in the space of six months - an extraordinary achievement. What you see here is only about
1/3 of the final design's complexity as all of the 'behind the dial' work is excluded as
well as that of the sun /moon rise set systems, perpetual calendar work and much of the
orrery. Even so, one can appreciate the intricacies involved with this movement.

The remaining photos have the orrery removed to give a better view of the interior of
the movement.

These photos show the anti-friction wheel system that supports the dual,
counter-rotating grasshopper escape wheels. Additional sets of ant-friction wheels are
used for the pendulum balance fulcrum points. See a video of the escapement mockup in motion.
