In this day and age, it’s hard to imagine someone making accurate clock mechanisms without using a single piece of metal. And yet, Andrey Martyniuk, a woodcarver from Belarus, manages to create intricate clocks exclusively from wooden components.
As a child, Andrey Matyniuk loved to sketch. He then got an education as an engineer, and later in life developed a passion for wood carving. After a master carpenter told him that wooden clocks are the pinnacle of perfection, he decided to combine all his skills to create artistic yet functional mechanism exclusively from wood. Bit it was easier said than done, and the ambitious woodcarver spent three years working on his first wooden clock. He tried copying the mechanism of a metal clock, but although the principle is exactly the same, there are two important things to take into consideration to ensure the clock measures time accurately – the softness of the material and the humidity of the environment. After years of experimenting, the master learned he had to increase the size of the gear teeth and treat the wood with a special compound to make it resistant to humidity. He also found that wood had a big advantage over metal – it has a much lower coefficient of thermal expansion, so it is much less affected by temperature changes than metal.
