Massive Wooden Gear Clock By Brendan Reilly

Clock designer Brendan Reilly created this wooden clockwork sculpture for the University of Waterloo in Ontario, Canada.

Massive Wooden Gear Clock By Brendan Reilly
The craftsman used black walnut, red oak, African blackwood and laminated Baltic birch for the gear mechanism.

This is a large clock, indeed: the large wheel is three feet in diameter, the dial is six feet five inches in diameter, and the pendulum is fourteen feet long!

The escapement mechanism is a variation of the "grasshopper" escapement invented by John Harrison. Harrison also developed the marine chronometer -- a fascinating story told in a book I highly recommend called, Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time
