Here it is: my cannon. It shoots large missiles, and shoots them hard. It is powered by 48 rubber bands, tied together into 8 strings of 6. It is 2 feet wide (on the bow) and 5 feet long.  It has an average range of about 100 feet shot from the resting position. It uses a ton of pieces, I know, though I might work on a smaller version later. If you do build my cannon, please know that I am in no way responsible for any damage done with it.

I have made a few other versions of this gun. Check them out!

Very nice cannon. I bet very few people have the pieces to build it. Since I build ball machines, though, I most definitely have enough.

degah127 months ago

This inspired me to building on instructables

I dont have NEARLY enough peices though. not even enough to make the handheld one

add a white rod to the front of the shell to make it more aerodynamic. Also, DEFINITELY USE IN KNEX CTF.

I love this gun i made this gun about 3 months ago and already i demolished a plant pot,exploded my knex box and a solid piece of wood!?? Best thing I've ever made
knex akbar1 year ago

reading the comments i'm not so sure if it's safe to build this thing...

Don't worry about that, it is very safe. As long as you be careful, because of it's structural integrity you will be fine. It's scary at first, but don't worry about it, just go ahead and do it! =D

I'm not worried about destroying something i'm worried about breaking my knex pieces XD

Hazza45311 year ago

I built this at a friends house over the holidays, fired the first shot which promptly went through a window, had to take it to pieces again :(

Pretty much tripling the size of this, and it is HUGE, and it is almost done! =D

Screw rubber bands! I use surgical tubing! IT IS INSANE, FOR I HAVE MADE A BIG MOD. >=) It shoots around 200-300 feet... I need more blocks of wood, nuff said.

Who has built this cannon yet? If anyone has built this yet please put a pic up.
I built it years ago. I have a picture somewhere but on a different computer.
It is so amazing how you can just sit down and make this from scratch... or your imagination.... but imagination sounds wrong...
I_am_Canadian (author)  BleSam1122333 years ago
Cheers my friend :-) My origional ideas generally need quite a lot of refining before they are presentable though..
Well, it does feel good to sit down with your K'nex and make something from scratch and get it right the first time.
I_am_Canadian (author)  BleSam1122333 years ago
Certainly, but for me at least, that doesn't happen often.

Cheers! Let me know if you do end up building.. Best of luck!
I am going to build it sometime when i count and inventory my K'nex pieces so i know how many of every kind of piece i have so i can figure out if i can build things a lot faster.
almost finnished with this gun i am still building the trigger though this gun is heavy
arent red and tan rods the same thing?
No, the tan rods are reinforced versions of the red length rods.

builder9684 years ago
Works great! I love it! Here's what it's been so far-

shot 1- rubberband caught on something, misfire. Repaired in less than 10 minutes, took it back outside.

shot 2- shot about 75 feet, ammo somehow split in midair.

shot 3- shot about 85 feet, would have gone farther, but a tree was in the way

shot 4- shot about 40 feet, rubber snapped, will re-string and try again tomorrow.
I_am_Canadian (author)  builder9684 years ago
Not bad, I guess...

Just make sure that you are using the right bands, and that you are stretching them out well before you put the on.
Yeah I shot it a few more times until it knocked a branch off the cherry tree(!) and my dad made me take it apart.
builder9684 years ago
Sorry if it seems like spamming, but I'm a little scared to fire this beast, because after 2 1/2 days of work, I don't want it to turn into the v5. I think that there's still pieces somewhere in my yard from that explosion.
I_am_Canadian (author)  builder9684 years ago
:-D

I'm still finding pieces in my yard, and I was shooting this thing around years ago.

nice gun
builder9684 years ago
And I'm short 2 wheels. I have 14,000 pieces, and I only have about 6 wheels.
Nvmd. I found a whole bunch(apparently I still had part of the v4 built) of wheels and got a huge box of about 450 rubberbands. Building this right now, In the middle of the bow, need to wreck some more models for the blue 3d connectors.
I_am_Canadian (author)  builder9684 years ago
Let me know when you are finished!
I did run into a small problem, and that's that pulling 2 strings back at a time is very hard, but it's avoided by pulling back one at a time, and it should be easier to pull back once the strings are a little more stretched. Hopefully I can get a few pics and a video up.
Finished, looks great, hope to shoot off in a couple hours.
builder9684 years ago
Step 6 hurts so much! ARRRRRGGGGGHHHHH!!!! Anyway, my thumbs fell like they were thrown into the cracks of Doom and then stabbed multiple times. The only thing that makes me want to go on is the fact that it looks like its smooth sailing froom here. Then I get to blow my backyard to hell.

is there a reason why on the bottom left of picture 9 theres no orange rods
I_am_Canadian (author)  laserbeam4 years ago
There aren't supposed to be any there :-)
mcoker4 years ago
It seems more like a ballista or a giant crossbow to me. A cannon usually implies there is some explosive force used to launch projectiles. But this has a bow with a rubber band string. But other than that, good job!! Really nice weapon. I can't wait to build it when my shipment of knex comes in. I already built the mini and it has done quite some damage on some cardboard boxes! =)
FlutterTree5 years ago
I'm REALLY scared to load 'cause when I had the micro the bow detonated on the second shot. (Although you'd expect that to happen on the first). P.S. I use #64's.
I_am_Canadian (author)  FlutterTree5 years ago
Don't worry, the bow on this one is much stronger than it needs to be.
when i bulit mine i had to dramaticly renforce the bow because it couldnt take the strain.
rangemaster4 years ago
I built this. then i made it bigger. we have just finished the Mk 5 and it is now 6 foot 4 inches long and can tear a beer can in half at 50 feet. just waiting for some latex tubing to power it and we are going for a record attempt. i use vastly modified rounds and a new rail system to gain a vast amount of power from what we call " Big jim ". will post videos on youtube when i work out how to link them here i will.

ninjusk5 years ago
this is by far the best knex weapon ever

Not by far...
PICT0003 (3) edit.JPG
That is the most overrated gun I have ever seen.
that gun is horrible. i tried to build and i did, but you know at the scope where you put the blue 3-d connecters in? ya, i had to take those out because they were stopping the ram rod

Thats not better....
agreed
hey man, groove with it or lose it. if you hadn't noticed oblivitus's Z-35 is the most reliable sniper online. his sniper matches power 3 times that of any average k'nex sniper. the only weapons that are better than his Z, is killerk's SR-V2 and his TR-18
It isn't a sniper and it isn't 3x powerful than an average knex sniper rifle.  First of all, it's a direct mag fed gun which makes mag friction and decreases range.  I've made an assault rifle that's more reliable and shoots farther than his, and it uses a true bolt action mechanism that separates rounds from the mag.

Second of all, blue rods are not the best ammo for range, Yellow rods are better, then Red rods are the best.  If you are looking at ammo that uses more than 1 piece, oodammo is even better, and then Sniper rods (Red rods with tape at the end) are the best of all.
Your AR-4 v3 is really good, but I sort of like the Z35 better.
Despite the fact that my gun is more powerful and reliable than his, I can see why you think that.  His is more realistic with a detachable clip, and can get faster ROF.  His is more like a fun gun than a serious performance gun lol.
I didn't say and didn't suggest that it was.
whassat?
My Z35 assualt rifle, look it up.
true  i  was not completely thinking when i make that comment.

in my mind   i have found many good weapons but this is one of my favs
(along with your z35, killerks sr-v2 and br 18)

This uses a lot of pieces! I'll make this after I buy more....

But this is by far THE strongest K'nex gun I've seen yet. I'd hate to be on the receiving end of that thing.

Perk1ns5 years ago
Darn, I have all the pieces required (even enough to give it the traditional color scheme, like you have) but I only have 2 medium wheels. I should be able to use Y connectors attached to snowflake connectors as substitutes, right?
I_am_Canadian (author)  Perk1ns5 years ago
Probably not, but smaller wheels would work.
Late reply, but never mind. While the Y connectors + snowflakes are not the best for holding the elastics in an unloaded state, they work well when loaded.
I_am_Canadian (author)  Perk1ns4 years ago
Cool! I wouldn't have thought of that.
I'm guessing that you could also use ball sockets instead of Y connectors (I'm guessing this would work better, but I cant test this as I only have 1).

Also, I word things pretty badly - I meant stretched/unstretched in my previous comment.
Perk1ns Perk1ns5 years ago
Wait, I lie. I mean the newer color scheme.
FINALLY done this step!!! i cant feel my thumbs any more :(
Better than painful thumbs I guess...
hey i have a problem with this cannon. when i fire it, the ammo exploads in the cannon and breaks the bow. can u please help me fix this?
Make sure that the ammo is built correctly first off. Be very sure that all the track connectors are clipped in, if not it will explode. Also make sure the bow isn't otherwise bent or anything. Thats all I can really think of.
can use this ammo for the handheld one two
I_am_Canadian (author)  mattiscool1144 years ago
Yes, just dont build the red connector on the back 3 thick.

imgonna build original when my weapon ban ends!
hehe
great instructions
the top barrel doesnt fit, whatever i will make it bigger
OMG I could make 2 of these!!! OMG
Make all 5 cannons!
maybe...
make a knex Gustav!
try make 2 then make them guard your room!
make 2 and fire them at each other it'd be a knex explosion!!!!!!

$100!!! That is an AMAZING price! I couldn't find one Screaming Serpant set for under $150! Where in the world did you get knex for that cheap?!!! Could you please tell me where you got all that knex?

Pizzapie5005 years ago

Hey everyone that knows knex prices! I bought this rollercoaster today
for $100. It consists of 2 rippin rocket sets, 2 screaming serpant sets, and 1 big air ball machine. It was 8 feet by 7 feet by 4 feet. This didn't fit into our minivan so we took it apart. Please tell me if I got it for a good price!

Rollercoaster 1.jpgRollercoaster 2.jpg
 Hell yes
Thanks! It came with the lights so on my next rollercoaster i'm going to put lights on it. The guy I bought it from said he spent $400 on knex and $200 on lighting. I cleaned all of the knex with bleach.
 WHY WOULD YOU DO THAT?? IT WILL RUIN THE KNEX!!!!!! :O
I didn't put a lot of bleach just enough to kill germs and make them smell good. They are still all the same color as usual and it didn't ruin the knex.
 ok then
Nice rllr coestar!! :) It's nice really......... oh and not a bad price for a roller coaster that big $100 ain't that serious, but the gun above is one hell of a price killer! XD, I'm not kidding I did a price estimate on this cannon a while back, and this thing costs like $500-$600. "THAT'S A LOT IF YOU ASK ME" XD.

Now that I think about it I'll make one of these and sell em for $400

Cool! I can make about 2 heavy cannons if the yellow connectors woren't needed. I only have about 400 yellow connectors
I_am_Canadian (author)  Pizzapie5005 years ago
Yes, you got a dandy deal.
Thanks, unfortunately it was in like 2000 pieces when we got it home. We also figured out he had a mouse problem or something, it smelled. So now we're going to wash each piece and bleach them. We've been working for 5 hours so far to take it apart.

I show you right on the parts list page what you replace them with :-p

Got some 9 hole squares for xmas so after we stop going places on winter vacation, i'll build this.

uhhh.....I have 2 screaming serpents, 1 rippin rocket, and 3 of  these colored box things with knex in them and I still can't build this......

Anyway, I need the bottom barrel and half of the trigger thing.
I_am_Canadian (author)  kevin29015 years ago
Sorry, I dont know what to say really...
Hey I found on craigslist 3 Screamin Serpents..1 Corkscrew Canyon..Hijacker..Cyber Knex..10 Pounds Of Loose Parts in a total of 60 POUNDS! For $75! Too bad it's in NYC...
ThomasRex5 years ago
If i wanted to make the rubber band strings only 5 long instead of six to make it more powerful i think the bow would be able to take the pressure but do you think the barrels could. I have made it before but took it apart to make another knex gun and i am finished with tyhis one for tghe second time i just have to put all the big peicers to gether. And would you recomend i dont shorten the strings or keep them how they are because i want to shoot it at like 150ft.

Which should i build for a war? The Blazer Sniper http://knexinnovation.net/forums/viewtopic.php?f=49&t=827 or the Inferno
http://knexinnovation.net/forums/viewtopic.php?f=49&t=66?
Btw i don't have many pieces left due to a ball machine that isn't finished yet and i might not have enough pieces for it either since it's about 20ft tall not joking. I'm working on one path and I finished the tower.
The inferno is reported to have mag issues, but the trigger is very good.
I_am_Canadian (author)  Pizzapie5005 years ago
Go for the blazer. And, I want photos of the ball tower.

You should include rubber bands in piece count.
Pizzapie5005 years ago
Oddly I can't reply... which is weird it leaves me at the waiting screen/thing. And I can post pics sometime this week. But i'll warn you it's just a tower and a part of a path but the tower is 20ft and i do have enough chain.
Woah i can reply to my own comment but not to another... Btw what sets did you buy?
I_am_Canadian (author)  Pizzapie5005 years ago
Thats odd.

I have: Big ball tower - Trampoline tower - Screaming serpent - a few other small ones.
Cool i Have like 6 of those boxes with various pieces. 5 of those amusement park rides mini pieces. Screaming serepent, Arcade, a tub that has hyper space training thingy, stego saurus, beginer set, advanced set. wanna see the instructions? My mom's camera only connects to her computer and i can't find the plug so it may take a couple more days till i can show u pics. Please w8 patiently...
psharpep5 years ago
Hey I_am_Canadian, would you consider editing this to also shoot sniper bullets? This is alot more powerful than the SR-V2, it's just the ammo is so frickin heavy! If you would include a lighter munition, this would be an epic sniper. Not to mention it would shoot at more than 200 fps.
arf2005 years ago
Thanks for the idea. Im going to take the v5 modife it and take the bow of this gun and use it this thing will be a beast
I_am_Canadian (author)  arf2005 years ago
Sounds sweet, good luck!

Finished it, but still need more ruberbands and time to test. I have half the ruberbands needed.

Hey what is the best knex gun to use in a war? Which means low pieces,good ROF, good accuracy, and powerful? Btw your spiff is inaccurate butwhen I put a yellow rod with a red connector on it, it's very accurate.I can shoot a target that is 1in wide from 15ft.
I_am_Canadian (author)  Pizzapie5005 years ago
Try the TR Series by KillerK.
He doesn't have instructions...
I_am_Canadian (author)  Pizzapie5005 years ago
He has lots of photos though. Not too hard to make it from thems.

ok, I bought tons of pieces so i can make a big gun. So whats a good rifle type of gun that has good accuracy, good rof, and good range?

I_am_Canadian (author)  Pizzapie5005 years ago

Do u know how many 38 pounds of knex is? Also is 38 pounds for $70 a good deal? Please answer ASAP cuz bidding ends today
Also is 38 pounds for 100$ better than Lost Mines:Power Tower Crane Big Ball Factory(Crankin' up the Big Ball) Hyperspace Training Tower Trampoline Tower Command-A-Bot(radio control) For $100?
I meant 38 pounds for $70
I_am_Canadian (author)  Pizzapie5005 years ago
I'm not too sure, but I can tell you that both are a great deal. If I had to go for one or the other though I'd probably go for all the sets. If you can afford/want both I'd encourage purchasing both though.
Um i meant which one has more pieces
I_am_Canadian (author)  Pizzapie5005 years ago
Prolly the lot.
Hiyadudez5 years ago
Hmm.. on the video, when you first fire it, does a bit of the bullet break off? Or a bit of the gun?
I_am_Canadian (author)  Hiyadudez5 years ago
Thats just a bit of the gun - there was a slight design flaw. It was fixed right away.
Ah, ok.
jtbuilder5 years ago
Hi I built this awesome cannon with my friend but when we try to pull back on the bands, they keep snapping in two. we made sure the track was the right length, and it was. I shortened the track by a few pieces but they're still snapping. Has this happened to you and do you know how to fix the problem???
I_am_Canadian (author)  jtbuilder5 years ago
Are you sure that you are using the correct type of elastics in the right amounts?
I am using size 64 rubber bands and made 8 groups of 6 of them
I_am_Canadian (author)  jtbuilder5 years ago
Hmm... Did you stretch them out fully before putting them on?
yes this is really hard to figure out
I_am_Canadian (author)  jtbuilder5 years ago
Could you make a video of the problem?
to tell you the truth, i dont have a camera I guess ill just try to execise the elastics before pulling all the way back
I_am_Canadian (author)  jtbuilder5 years ago
Yeah. And if the elastics are old get new ones - old ones are brittle.
i am still sad i am short on yellow cons idk bout green rods or white but i had all the other pecies for it

it must have the highest piece count of anything made out of knex-apart from some rollercoasters and ball machines-fine, any weapon on the site. am i right?
I_am_Canadian (author)  squarepants6 years ago
Erm, I'm almost posotive the vivisector has many more pieces.
ok fine, you win. By the way, would you check out my first gun, the knex falcon assault rifle? i'd like to see what you think of it.

thank god im finally gettin more knex, b4 i couldnt even make the hanheld (i have like no green rods!!!)
I_am_Canadian (author)  PieMaster7776 years ago
Shweet! Let me know if you build!
i definetly will build, but wit the amount of knex in gettin ill probably be ably to make the first/biggest version =)
Wicky6 years ago
Finally got round to making this, I am just gonna count pieces and build the biggest possible version. I don't think I have 255 blue 3d connectors though =d
Wicky Wicky6 years ago
Ah, going for V2, because I have 166 blue 3d connectors xd
I_am_Canadian (author)  Wicky6 years ago
Awesome :-D Let me know how it goes!
Hmm I think I am done building everything, but the shops are closed so I'll have to get rubberbands tomorrow; which in turn also means I can't assemble it yet xD. I think this is the biggest weapon I have built till now, took me 5 hours including breaks =x

P.S Picture is a bit blurry, my phone doesn't like shaking hands while taking pictures =d
Foto0095 (Large).jpg
I_am_Canadian (author)  Wicky6 years ago
Haha, thats so cool! Make sure to strech out the elastics before you put them on - too strong elastics can make the bow blow up and hurt you badly! I learned that out the hard way seeing how much power the trigger could take...
Made a small tweak and loaded it up with 6x4 big thick rubberbands.
I don't think I can fire this outside, as I need a wall behind it to load it xD

I'd say that this cannon works really well, very powerful, but a bit hard to reload lol. Most certainly 5*'s. Wonder why I am commenting on this one though =x

Bit dark pics:

1 Backside of box
2 Front side(right through teh lego truck )
3 Blurry =x
4 Rubberbands
5 Knob snapped off trying to fire the first time xD
6 Took a 2xpurple connector out and replace with yellow, these snapped loose from each other whilst loading and nearly imploded the bow xD
Foto0106 (Large).jpgFoto0107 (Large).jpgFoto0098 (Large).jpgFoto0100 (Large).jpgFoto0101 (Large).jpgFoto0102 (Large).jpg
Yeah I always stretch them before putting them on, however I get the feeling that these are just a bit thicker xd

As a backup I also ordered what I think are #64's (had same thickness and length) at a office stuff site. They call em coupon bands here, or something =/
I reccomend making two of these things, mounting them parallel to each other on some kind of heavy duty turret, and making the ammo function as a bola. painful, but it'd work.
you should take off a good quarter of the barrel because my dad makes real guns (not as sick as knex guns) and he say theres a lot of friction with the ammo and the barrel so it decreases range
I_am_Canadian (author)  I_am_English6 years ago
But all the extera space for the elastics to power the ammo forward makes up for it no doubt?
yer but im going to take the top barrel only 3 quaters so less drag and fritcion so it would probably beat 200 feet and a good degree angle
I_am_Canadian (author)  I_am_English6 years ago
Okay, if it works, be sure for a video/photos! Btw, at a good angle this could already hit just about 200, so with that it would go much farther.
seriously dude, can you cannon even do major damage or considerable damage ?
I_am_Canadian (author)  heatblast6 years ago
Obviously!
i got mine to shoot about 400 feet strait up!
I_am_Canadian (author)  matstermind6 years ago
:-0 I NEED VIDEO
it was with my bullet (look down), mine goes a lot farther than yours
I_am_Canadian (author)  matstermind6 years ago
Nice. I still want a video though :-D
i'll try to get one made, it may take a while though
I_am_Canadian (author)  matstermind6 years ago
Thats okay.
yer im only going to have the barrel were the ammo is (on the upper part)
I_am_Canadian (author)  I_am_English6 years ago
It might not work, but you can certainly give it a go. Good luck!
thanks for the heads up ! but i already did, with your v5. i'm laughing my head off right now. dude, it was awesome... and funny as hell. when i had your v5 loaded i aimed it at this junk car from the scrap yard, when i pulled the trigger i amazed at how fast the missle was going, the funny and also scaaary part was the impact that caved the passengers door in... im not joking, it did ... it really did. i also thought it was funny for the fact that what if it was really somebody's car.
I_am_Canadian (author)  heatblast6 years ago
LoL! Photos at all? Sounds awesome!
meh didn't have time for photos or footage, but i did put a number or two on that stupid car. oh look it's flabber from the beetle borgs... heatblast: afirmitive i have visual on sight, im taking aim, booom. flabber: " miss me, miss me, now you gotta kiss me" !! heatblast: oh sh*t, im outta here !!

I_am_Canadian (author)  Millawi Legend6 years ago
Its a little over the top...
hey i am canadian, how much tensile strength can this cannon stand ? i think surgical tubing is better because it has a tensile strength of 3,500 psi, but thats only 1/4th of it's actual power. here, this might help explain: Surgical Tubing Latex Physical Properties: * Standard Colors: Black or Amber latex surgical tubing * Tensile Strength: 3,500 PSI (Pressure per Square Inches) Minimum * Elongation at Break: 750% Minimum * Modulus at 300%: 190 PSI Maximum * Shore A Durometer Hardness: 35±5 * Specific Gravity: 0.95
I_am_Canadian (author)  heatblast6 years ago
I have no idea. I never tried adding all that much power, Because it would maim you if the bow split while you were loading up huge numbers of elastics.
what i meant to say was forget the elastics because they tend to break , however surgical tubing does not do that... it's life span is alot longer than a normal rubber band. i would recommend using it instead. hope that helps :)
Hiyadudez6 years ago
I Know this is really random, but i have nothing else to write: On Te yellow connector on the top of the bullet a tiny piece is broken off it where the green rod joins onto it.
bullet.jpg
that happens when you try to use pliers to join pieces together. (at least with me.)
If you do it right that wont happen.
True
I mostly use pliers to clip 2 rods together when they are filled up with connectors. Like Killerk's BR.
it happens on occasion though.
I_am_Canadian (author)  Hiyadudez6 years ago
Ah Yes. Ammo gets broken regularly with this cannon :-(

5* just finished it after two and a half hours of work. great power, I removed the extra bullet holders in the stand, and added a handle to the entire thing. next I'm going to make a easily removable stand.
I_am_Canadian (author)  matstermind6 years ago
Very nice! Thanks so much! Photos of the mods?
which one?
I_am_Canadian (author)  matstermind6 years ago
All of them!
the handle, this is just a temporary one, I'll make a more permanent one later I'll try to get the stand modified within the next few days.

To be sure!

I_am_Canadian (author)  matstermind6 years ago
50 cents was definatly worth your money.
Did you ever buy his album? The one called "Get rich or die trying"?
ps. I have a bad camera, (in case you haven't noticed) ;-)
That's imposable to make this gun in 2 and a half hours. That's one piece every 2.5 seconds non stop.
3.191489361 seconds and i started at 2:55 and ended at 4:24, I was racing against myself.
No way its possible UNLESS you gathered and sorted all of the pieces in advance and didn't count that time. I spend an average of 3 hours on medium sized things like the reaper or on of the smaller versions of this.
all of my peices are sorted by type, and color of type. so it makes it easier to build any gun.
Well sure but it must take a long time to take it apart. Anyway, that's too much of a hassle to do to every gun. I keep a few types of pieces separate but that's all.
thats the hard part about it. but it makes it ALOT easier to build the guns.
DON"T SHOOT ME!!!! 5*
