Cry havoc, under strict, competent adult supervision

 

 

The Tsar Cannon of backyard artillery, the Floating Arm Trebuchet kit includes the detailed instructions and pre-cut/drilled pieces needed to construct a finished trebuchet within a day (two hours for a master carpenter, two days for a layman without any kit assembly experience).

 

 

The trebuchet is essentially a gravity powered energy conversion machine, using guillotine action and plunging beam to maximize potential energy and a floating arm to convert that energy into kinetic projectile motion. This kit is professionally engineered, designed and manufactured in the USA. Made with 100% hardwoods, each part is precision carved by computer numeric controlled machinery for a guaranteed fit and accuracy.

The trebuchet is capable of throwing tennis and golf balls up to 100 and 200 feet, respectively; it's designed and intended to spark an interest in real-world science and engineering (and perhaps a bit of history, too). Test your machine's strength and efficiency with the included equations and tips as you watch classical mechanics in action.

Note: This is a functional model intended for educational demonstrations of physics. It contains a fast moving arm and projectile that can cause injury if you make contact when firing. Use only under the strict, competent adult supervision.

Tools required:

-Scissors, glue, ruler, a utility knife, small wrenches (for one 1/4" bolt and one 3/8" bolt)

-Sandpaper optional


Assembled Size:

- Height: 34"
- Length: 18"
- Width: 7" (frame) 12"


Additional Counterweights Required:

-10 to 15 pounds of coins, rocks, weight plates, or anything that can fit into the 4" x 2" x 6" counterweight boxes.
