The Ugears Marble Run Chain Hoist is an exciting combination of art and engineering. The Marble Run Chain Hoist is both a beautiful kinetic sculpture and an intricate toy that teaches as it entertains. This DIY wooden marble run features a chain hoist powered by a hand crank, and a series of tracks, each with its own unique and fun obstacle or element. Turn the handle clockwise to set the machine in motion, and watch as the wooden chain hoist collects and lifts the marbles to the top of the machine, where a 3-way switch distributes them on different tracks. One marble plunges down a chute with a loop-the-loop at the bottom; the next tumbles down the various stages of the cascades, while three others are collected in the accumulator then released down one of three short tracks. All marbles pass through the common tray or collector before returning to the chain hoist to be lifted on their next journey. The Marble Run Chain Hoist is modular, and can be connected to other Marble Run Chain Hoists (2 or 4 models can be connected, in pairs) using special connectors (included).
Everything you need for this fun DIY project comes right in the box, including pre-cut wooden boards, 10 marbles, wax, sandpaper (for optimal gear function), and a set of detailed, illustrated instructions. The Marble Run Chain Hoist has 400 pieces, is rated Advanced level of difficulty, and has an estimated assembly time of 7 hours. As you build this ingenious wooden marble run, you will learn about the action and interplay of drive gears and driven gears in gear sets, the delicate action of counterweights, and be intrigued by the mechanics of the 3-way switch and accumulator as they determine the marbles’ course. You and your family will have hours of fun constructing this DIY kit together, without need of glue or special tools.
Completed model size is 10.6″ x 12″ x 10.6″. Recommended for ages 14+.
