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.
<p>works like a charm</p>
cool <br>paper trebuchet
Thanks, although, personally, I prefer my original paper catapult.
Great instructable as always but needs a video.
Hi ya Im making this for a math class and it needs to fire a certain range. how far does this shoot?
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 &quot;just so&quot;. <br><br>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.
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!!
Cool!<br><br>You could all post a report of the results!
I don't understand how to fire ammunition will you please clarify.
Tie the ammunition onto a loop of thread.<br>Hang the loop over the paperclip.<br>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
Excellent, I'm glad it helped.<br><br>
HI PPLZ <br>
Hi.<br><br>(Who is &quot;Pplz&quot;?)
&quot;pplz&quot; is &quot;peoples&quot;for short
im with flanimal, you should really put up a video:D
What are the ranges?<br>Are they like. Epic range.<br>And what does the shooting look like?
Define &quot;epic&quot;. If you are four inches tall, then across a room is fairly epic.<br><br>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.
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.
Thank you.
Nice work! I'd like to try this soon.<br /> <br /> And, slightly unrelated...&nbsp; Is that what a soda tab looks like in the UK?<br />
Thank you, and, yes, it is.<br /> <br />
There's two types here in Australia, one looks similar to the British version.<br />
&nbsp;itz 2 flimzy<br />
Try it - it works rather well.<br /> <br /> <small>(You could also try using proper English as well - it's a site policy.)</small><br />
Ah, so you're adding onto the war game with your shed(s) and Kitemen infrantry. What will you add next Kite man?<br/><sub><sup><sub><sup>(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)<sub><sup><sub><sup></sup></sub></sup></sub></sup></sub></sup></sub><br/>
how do you make small text?<br/><br/><sup>I can only make it this small.</sup><br/>
add this <sub><sup><sub><sup> before and after your text.</sup></sub></sup></sub><br/><sub><sup><sub><sup>See?<sub><sup><sub><sup></sup></sub></sup></sub></sup></sub></sup></sub><br/>
add what?
