INERTIA

Designed and built by Ed Legler, 2003.

The Inertia clockwork was inspired by the work of David C. Roy.

To see David Roy's work:

Inertia is powered by a Negator constant force spring and runs for about 9 hours with a full winding of 22 1/2 turns.

The spring provides torque to the wooden gear train and ultimately applies force via the brass pins shown on the escape gear to the ebony pawls.

The flywheel, at the top of the piece, will accelerate slowly and turn a little over 8 turns in each direction.  The diameter of the flywheel measures 2 feet.

The title Inertia comes from the extreme sensitivity to the mass of the flywheel.  Slight changes in mass may change the running time by as much as 1/2 hour.
