This mini version of our World Famous Floating Arm Trebuchet is a real powerhouse in a desktop sized package.

The Floating Arm Trebuchet is a counterweight siege weapon which is a modern variation of the medieval trebuchet. The design and construction of such machines is a popular project assignment in post-secondary engineering classes. A great demonstration of mechanical energy and leverage at work, fun for kids of all ages. Kit: The kit contains laser cut wood, brass and copper fittings along with detailed plans. The floating arm trebuchet (FAT) invented by Ron Toms seemed like a good place to start, because the FAT’s weight falls nearly its entire height and it “shifts gears”: because the throwing arm’s axle floats, rather than having a fixed axis, each small movement of the falling counterweight results in an increasingly greater movement of the projectile.

As you can see in my son's video, above, the projectile never swings backward beyond its starting point, reducing the danger to bystanders behind the trebuchet. Throws a six gram wooden ball with amazing force, easily over forty feet with 200 grams of counterweight. The kit is very well made, durable, and easy to assemble. The trebuchet is essentially a gravity powered energy conversion machine, turning potential energy into kinetic energy and using it to throw a ball. Their defining feature is free movement of an axle on the throwing arm, and a linear drop channel for the counterweight. See more ideas about Catapult, Floating arm trebuchet and Woodworking.
