Outstanding clock! The Serpentine is a wooden gear clock. Its whimsical curves offer an artistic contrast to the more traditional Ascent clock. You can build this wooden gear clock from a ready-to-assemble kit. Or, you can use a scroll saw to cut the parts from do-it-yourself patterns. This wooden clock is driven by a 2-3 lb weight, and is regulated by a 48″ pendulum. The Serpentine runs over 26 hours per winding. It has hour, minute, and second hands. The Serpentine clock is about 26″ tall, 6″ deep, and about 12″ wide - Link.
