Step 2: Top Part

This is the part attatched to the trigger that pulls the catapult arm. The last three pictures show how it is attatched to the body.

<p>Better than the TR for sure!</p>
not the best range 1-5 ft if you made the barrel longer or a way to make the trigger pull faster it would fire better<br><br>
good gun
do u wnt me to make all of the picturs or no

Does this work without the band in response to my question?
Yes, it works without the rubber band, however it won't automatically return to the "cocked" position.
add a hopper or something and you've got semi-auto :D<br />
thx
interesting design, very innovative, 5*. could use a better handle though (fixed.)

really cool catapult-gun
how powerfull is it?
erm does it shoot ure self?
No it doesn't. You're probably holding it backwards.
lol ok
i did something like this earlier this year. I used dsman's crossbow's ratchet system so it used rubber band power.
I am currently making a mag for this gun... ill post when i can and if it works out.
it is pretty cool i was making it to destroy a lego castle but it didnt but it is a very good gun. nice idea
This could get some imagination flowing. good gun.
The design is nice and seems to work, but in reality this goes no more than 6 feet.
To be honest, I didn't design it for power, I was looking for a new way to fire things. So consider this a prototype. I may tweak the design to add more power, or do something like dsman suggested and use rubber band power for my next design. Thanks to all of you who like it, I'm glad you do.
I Like It and i would know, hence the name
this is the coolest thing on instructables!!!!!!!!!!<br/>lol<br/>=) =P <br/><br/>its so freakin fun!!!!!!!!!!!!!!!!!!!!!<br/>
I am am obsessed with catapults this is AWESOME!
This looks like a smaller version of my catapult, But better. This thing is awsome!! Great job.
nice! I might suggest putting it on a frame that is a blue length across instead of a white. That way you can have a sturdier frame and handle. good job, though.
this could be the new thing and it could be made semi auto
well, its not bad, but not powerful.maybe if you make is so the trigger holds the arm back, instead of pushing it forward, you could hook rubber bands to the arm to get more power.
Hmm...if you add a mag to this somehow, it would be semi-auto... This is a pretty ingenious firing system, like a handheld catapult +1 from me.
no......rubber.....band........ almost.......semi......auto..... +.........................1....................................... wow
New............... Wierd............. ....................................And I Like It...........................................
wtf? this is so weird! but good +1!
Crazy! i like it!
