Picture of The Paper Trebuchet
PICT2368.JPG
Moving on from my original Paper Catapult, this is an only slightly more complex model.

Rather than using counterweights like the later versions, I decided to use muscle-power and make a traction trebuchet.

Again, it's just a single sheet of A4, but you need two cocktail stick this time.

(I have posted this without a firing video because certain members have been nagging me to get it posted. I will do a video as soon as I can.)

Step 1: The Template

As is my preference, I drew the design by hand, in ink, on 5mm squared paper, referring back to the Paper Catapult for the base and frame. I made a couple of mistakes, but I include a scan of the original drawing for completeness' sake.

More useful for you, dear reader, I have also included a re-drawn PDF and JPEG of the template. Use whichever you desire (the JPEGs are probably the easiest to re-size, should you need to).

Print the template out on either normal 80gsm printer paper, or light (120gsm) card. If you print or photocopy to a size larger than A4, then I recommend using card instead of paper. If you use card but make it smaller, then careful scoring of crease lines will be required.

You will also need two cocktail sticks, gluestick, a paperclip, stickytape, pliers, sewing thread and small weights such as nuts or modelling clay.

Step 2: Preparation.

Picture of Preparation.
Whichever version of the template you are using, cut out all the pieces, then use one of your cocktail sticks to pierce the centres of all the small circles.

Crease all the dotted lines. If you are using card, or making a small version, then you will need to score the lines before creasing. Using a ruler, drag the tip of a blade of a knife gently along the line. You are scratching the surface, not cutting.
cool

Hi ya Im making this for a math class and it needs to fire a certain range. how far does this shoot?
Kiteman (author)  Yooy162 years ago
You know, I'm not really sure (I haven't made this again since posting, because I much prefer my original Paper Catapult) - there's a certain amount of skill involved in releasing the ammunition "just so".

Certainly it hit the wall of my shed (and the ceiling, and the wall behind me...), So I would say plan on around 8-12 feet.
Yooy16 Kiteman2 years ago
Thank you very much tht is great news. Almost everyone in my class has used your plans for the paper catapult, so keep up the good work!!
Kiteman (author)  Yooy162 years ago
Cool!

You could all post a report of the results!

I don't understand how to fire ammunition will you please clarify.
Kiteman (author)  Partex3 years ago
Tie the ammunition onto a loop of thread.
Hang the loop over the paperclip.
Pull the tab, the arm flips and the ammunition flies.
hi, its me again! umm kiteman, is there any other medieval weapon you made out of paper???
thanks, kiteman! This is a really awesome instructable because it is a real help with my 7th grade castle project!!!! :D XD
Kiteman (author)  ZoroThePirateHunter3 years ago
Excellent, I'm glad it helped.

HI PPLZ
Kiteman (author)  ZoroThePirateHunter3 years ago
Hi.

(Who is "Pplz"?)
"pplz" is "peoples"for short
im with flanimal, you should really put up a video:D
What are the ranges?
Are they like. Epic range.
And what does the shooting look like?
Kiteman (author)  Jimpiedepimpie3 years ago
Define "epic". If you are four inches tall, then across a room is fairly epic.

Look like? Pull the tab, the arm flips, the ammunition flies...

wow this is so cool if only i knew how to get the template printed, lol, oh well, very cool.
Kiteman (author)  SaberSaver5 years ago
You don't have access to a printer??
I do but I always have the worst luck with computers, I think they hate me, or maybe I just cant understand them.
don't try linux :P

This shoots very far for it's size! Nice work! Airsoft bb's work well.
Kiteman (author)  danbaha4 years ago
Thank you.
nickodemus4 years ago
Nice work! I'd like to try this soon.

And, slightly unrelated...  Is that what a soda tab looks like in the UK?
Kiteman (author)  nickodemus4 years ago
Thank you, and, yes, it is.

There's two types here in Australia, one looks similar to the British version.

Try it - it works rather well.

(You could also try using proper English as well - it's a site policy.)
Ah, so you're adding onto the war game with your shed(s) and Kitemen infrantry. What will you add next Kite man?
(I have concluded that your Kite man, not Kiteman. And thanks for teaching me how to make small text. Perhaps there is still time to make you in to Kiteman)
how do you make small text?

I can only make it this small.
add this before and after your text.
See?
add what?
comma comma shift+ six comma comma shift+six
comma comma shift+ six comma comma shift+six like this

weird
Yes you are

i don't get it

you wouldn't....
you have to have had the email sent to you.

I'll try to tell you with words:

comma comma carrot comma comma carrot

so it looks like this (without quotes)

""
well, that last part didn't work. but yeah, you can tell from my words.

I wonder if you could pair a carrot and that...

is it too tiny to read?
lala
hello
hi
zoom in on that.
ha, you can barely make it out when fully zoomed.
you can just copy and paste it into your adress bar -_- it says lala right?
si. pero es muy peqeno. there should be a tilde on the n, but I don't know how.
nope.
i added that x 2 lol lol
that dot near lol says lol! i put comma comma carrot comma comma carrot comma comma carrot comma comma carrot comma comma carrot comma comma carrot
does this work?
thanks
likethis
I'll try yours.

I'm trying it here.

hello

 anyway, now i have a catapult and trebuchet
TO WAR!

 .{{{Does this make it smaller?}}}.
I am soooo going to try this!
knektek4 years ago
about how much newtons or grams of weight can this hold?
Kiteman (author)  knektek4 years ago
I've never tested it to find out.

The best answer would be "a few grammes" - nuts and bolts, that kind of thing.

you should put up a video:)
cocktail sticks are the same thing as toothpicks, correct?
Kiteman (author)  Future filmaker5 years ago
Similar, but toothpicks (I think) are smaller. Cocktail sticks are the things they poke through olives in bars, or through lumps of cheese and pineapple at tacky parties.
can you buy cocktail sticks? and where?
Kiteman (author)  the poodleo5 years ago
I buy them from my local supermarket - they tend to be in the bakery section, near the paper bun (muffin) cases.
Nothing like a fresh-killed muffin. =D
Kiteman (author)  Lithium Rain5 years ago
I got a pleasant surprise the other day - I had a "triple choc" muffin, and the third chocolate turned out to be a big dollop of sauce in the centre of the muffin - warm and gooey!
Oooo, nummy! :)
Kiteman (author)  Lithium Rain5 years ago
See - how is this "not fitting in"?
ah, got it
I dont get how to fire it
Kiteman (author)  Electroinnovation5 years ago
The string goes around the curved part, under the bottom cocktail stick and out the back - tug the string and the arm flips.
so it is not at all a trebuchet is more like a catapult because the trebuchet works with weight at one end and the projectile in the other end
i geuss you and i will be nerds 2²ever...
Kiteman (author)  MrMystery965 years ago
Cute.
hippyland25 years ago
i like the launch it : the paper catapult better but i like the idea
MrMystery965 years ago
well done, as usual from the all mighty kiteman. although, i thought a trebuchet used a counter weight AND a traction setup to hold, load and fire. anyways, once again, your talent has made us all happy. so long and thanks for all the fish.
Kiteman (author)  MrMystery965 years ago
Ah, call it Makers' license...
pie R []ed5 years ago
I taped all the way to the base of the curved part and found that if the arm stopped there it flung the ammo constantly in the highest ark possible.

Crap, right after i finished i realized i didnt have any toothpicks
Forgot to say great instructable... i hit post comment to fast

can u use duct tape
daniel19935 years ago
My 10 year old son had to make a trebuchet for his homework so we thought the paper version was a great idea. We decided on a slightly thicker paper and instead of using a paper clip, we cut down a small plastic spoon. We also used sticky tape as well as glue as my son didn't think it would be strong enough with just glue. We tried it out, firing some blutack and WOW!!! it works. My son can't wait to take it to school on Wednesday.
Kiteman (author)  daniel19935 years ago
That's great - maybe you could post a picture?
tengaman5 years ago
i made alot of the originals but can u put in the size for 8.5 by 11 also known as letter paper i dont mean to seem rude but i want to make the right size so can you?
Kiteman (author)  tengaman5 years ago
If you click the i in the corner of the second image on step one, you can download a jpeg of the template.

That can be made any size you want - just remember to keep the proportions the same, or the parts won't fit (ie resize it, don't stretch it).
pyro13245 years ago
I made it in carp board paper size A-1
Kiteman (author)  pyro13245 years ago
A1? Any chance of a picture?
it kinda fell apart.
=(

i took a rock and tried to fire not a good idea!
Kiteman (author)  pyro13245 years ago
Aww...

The two images in the intro are great! I have done the same with a couple of my projects (see my living room Web page). Did you make the rendering before or after you completed the assembly? Or did you arrange the loop and pull tab to match the drawing?
Kiteman (author)  kelseymh5 years ago
I actually drew over the photo in CorelDraw, then copied and pasted the drawing into Photoshop Elements, which I used to add the shading and colour.

There are probably easier ways of doing it, but that's what I'm comfortable with.
Ah, okay; thanks, Kiteman! For the drawing, I wonder if SketchUp supports doing both a 3D rendering, and then "unfolding it" to get a first-pass at the paper cutouts. Your method produces much better looking (more realistic) drawings, I think.

Shameless self-promotion For a couple of my projects (our living room and Madeleine's crib) I did the drawings first, as design concepts, and then made the photos (or photo-collage) afterward to match.

Kiteman (author)  kelseymh5 years ago
I've never used computer software to originate a net, it's always by hand. It's weird - when I want to make something like this, the actual design process, bar any small aesthetic tweaks, all happens in my head, the finished product and the net both sort of "appear" at the same time. I can "watch" the net fold up into the finished item, and vice versa, in my head, before I commit pen to paper. Sometimes, it is so clear I can use ink instead of pencil, I am so confident it will work.
