The K'nexecutioner 2.11 - "Cyclone" by Perfect Duck
The long-awaited sequel to the original extra-heavy K'nex machine gun, Cyclone wipes the floor with its predecessor in every category - power, range, portability, versatility.

Designed to be the most powerful* K'nex fully-auto machine gun yet. Really - every single round of Cyclone's belt carries some decent strengh for a K'nex gun.

- If you have enough pieces, build two! It's one-handed.

- Unlike its picky predecessor, Cyclone has an open front and can use any size of rod for ammo. This includes flighted 'sniper' rounds.

Version History (updated):
2.0 - "Cyclone" first created but kept classified. Based off of the likewise-named weapon from Perfect Dark, it was powerful and fast-firing, but pitiful that only 17 of 19 barrels were usable.
2.1 - Extensive restructuring was necessary to make it fire from the top where barrels are further apart, instead of the side. This new layout is more compact.
2.11 - Significant improvement made to ammunition belt allowing for variable ammo sizes.

** Before you build: Know that not all K'nex motors are made equal. Some K'nex motors (at least a few of mine that I know for sure) are incapable of being used on the Cyclone because they too easily start clicking under too much load. Proceed if you are confident you have a good motor. Just a fair warning. **

*Hardest hitting, not fastest rpm.

Step 1: The Ammunition Belt

If you haven't the parts for the ammo belt, there'd be no point in continuing past this step, so let's get the tedious, hard, annoying, etc. part done first.

Find an efficient method for building them, else you'll be spending a lot of time on this step. (okay, it will take a long time regardless)

This step alone requires:
209 dark-grey connectors
209 blue spacers
57 grey spacers (each counts as 3 blue spacers)
57 black chain-links
57 red and light-grey connectors
.. among other things.

Use 2x type 64 rubber bands only! Too much power may result in broken K'nex pieces.

For simplicity's sake when attaching and removing the ammo belt, make sure that every black chain link is facing down.

Cyclone requires a specific number of barrels, unlike other open-belt machine guns. 19, to be exact. Get to it!

This is very awesome

Great but I do not have that much chains

Love to make it

Absolutely amazing. A bit heavy though and the chain will only turn if you have a powerful motor but still great.

i have the dulexe simple machine and another set that include about 1000 pieces and 8 more punds and i think i can build llike ten of them if i dont include the moters in 8 of them
weadeadr says: Mar 13, 2011. 6:23 PM
better than the one with twin belt(simple and seem easier to make and it looks light wieght
Fred the evil puppet says: Feb 22, 2011. 11:45 AM
and how much time exactly do you have on your hands?!?!
and to make two i mean holy s***!!!!!
travw says: Jul 18, 2009. 9:02 PM
I know this is an old gun, but here's what I think: It's way too front heavy, and I had a problem with the elbow rest breaking off, it's pretty powerful and has a good range, but I would never, never use it in war.

*3.5

UHHM mOuNt It !!!!
travw says: Sep 23, 2009. 6:20 PM
Ok, again, what's with ThE sTuPiD eVeRy OtHeR bEiNg A cApItAl ThInG?!? There's no point! Secondly, I posted that comment "Jul 18, 2009. 9:02 PM".

i like caps srry...
travw says: Sep 23, 2009. 6:46 PM
That's ok, it just makes it really hard to read. And, again, there's no point.
But we cool. =p

looks like one of those gods-forsaken capchas (f***ing hat those things)
KnexFreek says: Sep 23, 2009. 7:12 PM
ok
Mace! says: Jul 25, 2009. 1:59 PM
Why wouldn't you use it in a k'nex war? If you want to use a machine gun then you would use this one.
erikos kostarikos says: Aug 20, 2009. 9:12 AM
excactly...
DJ Radio says: Aug 13, 2009. 7:40 AM
The only reason I wouldnt use this in a knex war is the reload times.
Mace! says: Aug 22, 2009. 12:57 PM
So you would'nt use a machine gun period...........
DJ Radio says: Aug 22, 2009. 2:21 PM
If it doesnt require me to reload, I would use it. Otherwise, its a disposable gun.
Perfect Duck (author) says: Aug 22, 2009. 6:35 PM
It's the opposite way of thinking for me, I see the reloading of machine guns as potential and not a drawback. Scenario: Say you have 19 shots. You fire 5. You have the time to load 2 more shots. You have 16 shots left and fire another 10 (perhaps too many), but an opposing player is outgunned and defeated. You use cover that you've gained to reload, and this time manage to reload 11 barrels, a few at a time. Now you've got 17 shots, etc. You have the ability to spend your idle time building up a very powerful multi-shot attack that you can use and dispense freely, and then once you're safe you're back to building up that potential again. The Cyclone is always ready to fire at moment's notice and you can easily take advantage of safe cover. Cyclone reloading is simple, you pull the pin back, the trigger for that individual pin will automatically set itself, then you reach to the front to slide a rod in, and set the holder and you're good. Reloading all 19 at a time would be cumbersome but doing it one, two at a time in the heat of a battle scenario could be easily pulled off. Hope that dispels a bit of your concern about reloading, but if you still think it takes too long, you're probably right because other K'nex weapons ARE easier to reload, I'll admit. The biggest competition are pump-actions.

or you could make extra chains.
Fred the evil puppet says: May 29, 2011. 1:38 AM
*facepalm*
Mace! says: Aug 29, 2009. 11:23 AM
Exactly how I use it in a k'nex war.
DJ Radio says: Aug 29, 2009. 9:56 AM
Im going to make a knex gun that has the ROF of the knexsayer, but has the fast reload times of my AR-4 v3. But yeah, your system does sound solid.
smattman22 says: Sep 7, 2009. 6:42 AM
how do i find or start a knex war?
travw says: Sep 7, 2009. 6:11 PM
Go start a forum or something, don't be a dumb@$$ and ask on a random instructable.
smattman22 says: Sep 7, 2009. 6:15 PM
rofl
travw says: Sep 8, 2009. 5:34 PM
How was that funny?
travw says: Aug 29, 2009. 2:03 PM
Well, actually, I can reload a Knexsayer faster than an AR-4 v3. Which is odd, considering AR-4 v3 holds less rounds than Knexsayer.
DJ Radio says: Aug 29, 2009. 2:07 PM
The newest version holds 1 more round than the knexsayer. The modded one has a 9 round hopper, which I think you have not seen....
travw says: Aug 29, 2009. 4:21 PM
Oh yeah, I forgot about the newest one. Sorry.
DJ Radio says: Aug 29, 2009. 4:49 PM
not to mention the fact that you can load up to 3 rounds in the hopper at once.
travw says: Aug 30, 2009. 1:11 PM
True... Didn't think about that.
DJ Radio says: Aug 30, 2009. 1:55 PM
;-)
KILLERK says: Aug 26, 2009. 12:14 PM
hey man what u been up to? i love this gun
smilee says: Aug 27, 2009. 7:46 AM
Okay then I'll post it then thanks for you permission!
smilee says: Aug 26, 2009. 4:47 PM
I made instructions NOW post your tr8?
smilee says: Aug 26, 2009. 4:47 PM
NOW can I post your tr8?
travw says: Aug 13, 2009. 1:48 PM
True, but if I did use it, I'd probably unload the whole thing, then switch to a different gun.
travw says: Jul 25, 2009. 3:21 PM
.....Because of what I said??? Maybe if it was mounted on some sort of rotating turret, but otherwise, the back portion breaks off and the whole thing plops to the ground... There were broken pieces everywhere!!1 Want that to happen in the middle of a battle?
Perfect Duck (author) says: Jul 25, 2009. 8:49 PM
You must have built it incorrectly because the elbow rests hold true to their structure even when I swing it moderately into the load-bearing section. I wouldn't post anything that is prone to structural failure. As far as it being front-heavy, I also created a mod for it that gave extended structure out the front of it, providing another handle in the front far out enough so that it doesn't interfere with yellow rod sized ammo. I never posted that version, though.
