Life size k'nex war cannon

Here it is the best of the best life size (or almost life size) war cannon. Yes I know there are lots of knex cannons on Instructables but this one is different from the rest. It looks like a cannon. It will shoot 60 - 70 feet with 2 rubber bands ,and will shoot though 4 pieces of paper. This does use ALOT of parts so I took the time to take a part count so you don't waste your time. It uses a more simple trigger Then IAC cannon but it(kinda) uses the same mech.

PROS:
looks great
wonderful distance 60 - 70 feel with 2 rubber bands
will completely destroy 3 pieces of paper

CONS:
uses a lot of pieces

Step 1: Part count

RODS:

76 gray

70 red

37 yellow

27 blue

55 white

100 green

Connectors

17 white

40 blue

44 yellow

58 purple

70 green

27 red

6 gray

11 orange

misc:

4 gray clips

8 small gears

I can't give a number of spacers. Because the number will differ for each person.

18 black hands

2 rubber bands

[Seleziona]

 rofl!

[knexgunbuilder217]

do u have to use the flexi-rods for the barrel

[bob the HUNTER]

dude this thing rocks just built but the only down side is that is does not shoot good for me

[skyfaller]

This is good!

You should check out I_Am_canadian's knex heavy cannon.

[Brad G]

Modded this quite a bit, ALOT less skeletal it looks pretty awesome ;) fully metallic shoots a bigger projectile (like IAC Cannons) and the end of the barrel is modded a little, i will try and get pictures thanks for making this great cannon ;)

[instruct39]

you need cannon ammo not little tiny ammo u cant find after shooting it, other than that very cool! 5*

[clader1]

dude it doesn't go 60-70 feet. you lier i shot it it went 150-200 feet !!!!

[dnmonsen]

cool

[matsermetsuiker]

lol XD its really cool!

[Furloy]

 4.5 stars, it skeletonish

[Killer~SafeCracker]

I gotta say it looks good. 4.5*

[codemaster2590]

i think that it is really cool but i do agree that it could use more reinforcement. I think that it would be cool if you made it a breech loading cannon if you made any mods to it.

[knexkrazy]

Thanks! I'm working on a second version that has more parts, but it takes a lot of pieces.

[Bartboy]

Umm? "second version that has more parts, but it takes a lot of pieces." LOL

[Killer~SafeCracker]

LOL

[charlie farthing]

so how far can this canon shot 70 80 feet or is it a low range gunthat can only shot about 20 feet

[Jesus.]

lol it say right there /\ /\ /\ /\ /\

[Skreetsha]

Cool! A bit skeletony but, it probably functions as it looks, and that would be great :D 5 stars!

[I_am_Canadian]

Oh yeah... Nice wheels Nice pictures.

[alfpwns]

*BOOM* OWWWWWWW

[builder968]

pretty cool. I know i dont have any howework tomorrow evening;might build.

[builder968]

then again, i might not. might build on sunday(saturday i have a friend's party).

[arrow shot]

nice, but i hardly believe that cannon barrel is life sized...maybe provide us with a picture? of the real thing>?

[knexkrazy]

This is the cannon I was modeling it after. Of course I can't go true life size without using a TON of parts. But, I called it life size because it is VERY big and looks pretty much like the real thing.

[arrow shot]

Yeah, it actually is almost life sized...If i had to guess, i would say 5/8? Havent built this yet though, so idk...too many peices for me XD

[apples!!!!!]

Now I don't know if I want to work on the one I wanted to....

[yerjoking]

Wow, I'd just love to sit at the back then fire it at someones face, they'd get owned lol.

[Master_Zane]

Sweet! Looks Great!

[knexkrazy]

thanx

[uguy]

Life size?

[knexkrazy]

I said in my intro that it was "almost" life size. Actually, it isn't too much smaller than some cannons, but obviously not "real" life size.

[DJ Radio]

cool, also love the realism of a civil war cannon. 5*

[knexkrazy]

Good, I'm glad you like it. I was trying to make it look realistic.

[I_am_Canadian]

Very nice! A tad "Skin and bones", but there is no great way around that without using a load of pieces. Nice work!

[knexkrazy]

Yes, I agree. I'm working on a second version that has more body to it. You are right though - it takes a ton of pieces to make it fuller. But, this one works very well and is a lot of fun to shoot.

[pls]

thats looks great:)

[the_burrito_master]

lol nice it v=could use some more detail/re-enforcing but pretty good.
