The "David" Wooden Gear Clock is an homage to the clockmakers of years past. The timepiece is powered by a falling counterweight it and measures the minutes with a gently swaying pendulum. No batteries are required.This kit includes over 100 parts precision cut from select birch plywood and clear poplar hardwood. It features 12 bearings, carbon fiber axles, and comprehensive instructions.
As a precision instrument, assembling this kit requires patience and careful attention to detail. The reward for this challenge is beautiful hand-crafted wall clock. Once built, the rhythmic ticking and moving gears will capture attention and spark conversation.
When Galileo wasn't busy building better telescopes, studying the heavens, proving the earth is round, and generally upsetting people that thought science was heresy, he would devoutly attend church. I'm not saying he wasn't paying attention to the services, but he spent a lot of time watching the chandeliers gently swinging back and forth. The story goes that he noticed how chandeliers of different lengths swung back and forth at different rates, but that each chandelier, no matter how far it swung back and forth, did so at exactly the same rate.
It occured to him that a pendulum, (basically a simplified swinging chandelier) could be used to make an accurate clock. He worked out a plan for a pendulum-regulated time piece, and described it to his son. Apparently his son started to build it, got bored, and said he would finish it later. He successfully procrastinated until both his father and he died, and Galileo's design was never completed. (That's my version of the story. Don't believe everything you read on the Internet)
It took fifteen years before Christiaan Huygens, a Dutch scientist built the first pendulum clock (shown). Before long everyone wanted one, and they spread throughout Europe.
According to Clayton Boyer's book, "A Practical Guide to Wooden Wheeled Clock Design" wooden gears were used for clocks in the American colonies because they didn't have access to the tools and materials to build the metal gears that European clockmakers were using in their timepieces. The gears on these colonial clocks were hidden away like that skeleton in your closet.
Only over the last few decades have these wooden wheeled clocks emerged as pieces of art.
