Lego Trebuchet

Posted by ryuzaki0 on from the i-think-i'm-gonna-hurl dept.

An anonymous reader submitted linkage to a trebuchet made of legos. Using australian coins for counterweights, it is able to throw a marble 50 feet or more. I wish they had some photos of it in action, and maybe some schematics for do it yourselfers, but regardless, looks like a fun project if you have a pile of legos and a 4-day weekend ;)

  1. Design similar to one seen on Junkyard Wars by nweaver · · Score: 4, Interesting

    The "Floating Arm" trebuchet design was used on an episode of Junkyard Wars.

    IN that design, the arm has two wheels, and runs on a track along the top of the trebuchet, while the counterweight drops purely downwards down a vertical track.

    It wouldn't be suitable in midaeval times (due to the wheel on the arm), but is quite easy to do for modern designs, and nicely effective (as you no longer have the big counterweight swinging along, but only going up and down, something easier to engineer for with Legos).

  2. Tinkertoy Trebuchet! (aka 'Tinky Flingy') by Shayde · · Score: 5, Interesting

    Feh, that's nothin! Too many parts, too easy to fail. What you -really- want to do is make a trebuchet out of -tinkertoys-.

    Like I did!
