Introduction: K'nex Javelin MW2 (w/ Top Attack!)

veryone, as my first instructable, this is a accurate remake of the Javelin Weapon system. The knex equivalent features a fire selector switch, (top attack, ground fire) safety, and quite a strong kick. The trigger is still a bit sketchy, but nothing a few mods can't handle ;). Anyway, on with the instructable!

This rocket launcher is very versatile and can be used in a variety of situations. For example, in a k'nex war, it could be used to destroy bunkers, or fortify positions.

Here is a video of the finished product. As you may notice, it barely leaves the barrel. This is due to the fact that I only used 1 weak rubberband. I have got it to shoot about 80ft, and with the size of the projectile, that is rather formidable. 

EDIT: This thing has been rated 3.42?!??!? Are you serious!? Thanks guys :D




Step 1: Main Body (pt. 1)

 Here is the first handle. If you can't build it from the pictures, please don't attempt this project. 

 

Step 2: Main Body (pt. 2)

 This is a continuation. A little bit trickier, but still if you cannot manage this, please stop now.

Step 3: The Rocket Tube!

 This is the guts of the Javelin, this is where all the magic happens! If you can't build this, please stop now due to lack of logic. 

(P.S, Please pay close attention to where the yellow connectors go...)

Step 4: Last Things

 Just the fire selector and trigger. Basics! :)

Step 5: Putting It All Together

 Nearly there! Doesn't it look good? Make sure that you follow the steps closely. Don't want to ruin your good work! 



Step 6: Done!

 Now have fun scaring your enemy with a huge missile launcher. Remember, play safe!

I built this. It was pretty cool. Also, when my friend and I were playing Cod, we both used Javelins and Riot Shields.

 Isn't it obvious? You put the rubberbands on the top two yellows on the front, then pull it down so that it looks like it does in the video. Please use logic next time before posting dumb comments. ><

I know how to fire and how to make the bullet.
But i dont know how to attach the trigger to the rocket tube!

author
willdebeers (author)cool bas32010-03-07

 Its quite simple...There is one of those bendy connectors, you take that and click it onto the rod that goes down the side. Did you actually build it? Because if you did then you would understand.

cool bas3 (author)willdebeers2010-03-07

OH THANK YOU! It works very good now!
Only the reloading is a  bit uneasy

author
willdebeers (author)cool bas32010-03-08

This would be a great gun if there was a picture of the assembled trigger. Unfortunately, there is not.

author
mettaurlover (author)knexcannon2011-01-02

You don't. I've been trying to figure it out for days, and I still haven't gotten it to work.

author
DrWeird117 (author)2010-07-08

Wow. I've seen it all.

author
the poodleo (author)2010-06-04

no offense, but it kind of looks stupid, because on the video it only shoots a little bit in front of it before it plummets to the ground. that other video was awesome though.

author

You didn't read the description then.

author

well yah look at the first video though! i mena, it barely makes it out of the tube before it gos down.

author

He said he used a really weak rubber band.

lol on the youtube window i went from ur gun's shot to a freakin A10-Gatling gun test

I tried to build this but couldn't figure out the trigger, so I took the barrel and attached IAC's V4 Heavy Cannon trigger to this and added a handle to the top so I could fire it. Haven't got a chance to fire the thing yet, but I've strung it like you would IAC's cannon without the actual bow. I have a feeling that it'll break stuff :D

author

I changed the handle to be an arm harness of sorts so I can rest its weight on top of my arm and fire from that position. I think that my mods make it a more viable war gun, while using a comprehensible trigger. I also couldn't figure out your ammo, which I think is a worse problem than not figuring out the trigger, so I just used a random piece of ammo I threw together that fit and added a couple pieces so the trigger could grab it.
