Gravity

Named for the escape mechanism, with a beveled glass case made of solid cherry, this spring-powered table regulator is the most elegant clock I’ve made.

It runs beautifully, with a very interesting, quieted sound.

(The reflections on the glass made this clock hard to photograph.)

The escape mechanism is a six-legged modified “Arnfield” Gravity. Only one arm impulses the pendulum. The other arm is unlocked by the (gravity) force of the impulse arm, and thus the pendulum remains mostly detached from the train forces. The “barbell”-looking thing on the escape shaft is a friction-mounted inertial governor - eliminating the additional gearing that would be required for the fan-type fly normally used on a gravity escape.

The cherry wood has aged to a gorgeous deep orange-brown color that changes with the light. The “beveled glass” is actually plexiglas - much easier to cut and bevel with my hand tools! (not to mention $)

As on many of my clocks, the dial is designed on the computer, printed on photo paper, glued to wood, cut out, and finally finished with about a million coats of lacquer. It looks like “porcelain on wood”.

The door opens for winding.

My “signature” and the brass winding key reside in the bottom.

I really love this Sinclair-Harding Table Regulator.I couldn’t afford it, so I built it.It may be my best clock.
