A friend of mine wants to build a trebuchet as a class project.  Something about 10 feet tall, with maybe 100 to 150 yard range.  I plan to set him up with some saw horses, a bunch of 2x stock, and hand held power tools: jig saw, circular saw, drill, and driver.  He's got some money for wood and hardware.

 

I told him to start by searching the net for plans - no reason to do a lot of trial and error when it's already been done.

 

Anyone have trebuchet plans they could recommend, or experience building a trebuchet?

No plans... but 

 

Ours didn't go nearly that far.  (one, we built it indoors, two, it was built to scale, three, we didn't use a projectile you can find after launching.  The wall was 8 feet from the trebuchet, so I know it didn't go scale distance.  Just not sure how close it would have come.)

No but I have launched a few pumpkins with one. Went to a party last year and the guy had one built out of metal. His was simple and it worked ok but think I could build a better one out of wood.

Years ago a guy in my shop scaled up one from a magazine article about 3 x. 10 lbs of lead threw a rotten piece of fruit well over 100 ft.

We built trebuchets at a firm retreat as a team-building exercise.  They came from a kit and were made out of luan.  Threw a golf ball a hundred yards.

 

I would think that a properly constructed 10 foot trebuchet, with appropriate weight, could throw things a quarter mile or more.

Myth Busters or someone built one to throw a piano. Should find a link if you google. I know there was lots of talk about the wheels. The machine needs to sway for maximum effect. I am on vacation, I'll dig

Designed for ShopBot by TJ Christiansen

Overview: This medieval launcher would reek havoc on enemies castles. However, the modern day conversion using 20lbs of weight will easily through a tennis ball the length of a gymnasium. Teach students about history, trajectory, mathematics, etc. Enjoy.

Materials:3/4” plywood, 2’ of 5/8” threaded rod, 3’ of 1 1’8” dowel, 12 1/4” dowel pins

Minimum Cutting Area: 2 sheets of plywood that measure 4’ x 8’

Bit Size: 1/4”

Finishing:Spray paint works great to accent the gussets. A polyurethane coating will cover all of the natural wood and seal it up.

Thanks!  I've got  Sketchup at home.  At work I've got access to AutoCAD and Solidworks, and probably other stuff.  If necessary I could print our views for the kid who's doing the project.  

 

I don't want tot do too much for him.  Not because I'm lazy, but because it will be a better experience for him.  Really.  Not laziness at all.  I'm only thinking of the children.

==>wants to build a trebuchet

Wonder when they'll become regulated? Now that the ATF has been renamed ATFE, guess they'll have to print new stationary with ATFET... :)

 

You know, you might just need a Class III FFL to purchase --- and maybe a Class IV to build... :)

 

But you can just forget about getting a concealed/carry permit for that bad boy :)  Well OK, maybe in Texas... :)

That video is cool. Didn't watch it all, but that trebuchet looks almost the size of another I saw on Youtube. Some guy in Great Brittain was flinging compact cars across the fields of his castle estate with it. He could toss a cooper mini about 100 yards.

I've built a very small scale one. The best advice I have is make sure you have good wheels under it - your projectile will go much further with them. We didn't have plans, we just built it on the fly

I think us Brits have a bit of a thing for trebuchets:)

If I recall my ancient history correctly, weren't your ancestors on the recieving end of some of these machines?

My ancestors have been on the receiving end of most things over the years. The family castle was destroyed during an English raid in 1545. I dare say that they used trebuchets then :)

Gotta give you guys credit though, a good single malt can get you through most troubling times!
