Introduction: Simple K'nex Machine Gun

Picture of Simple K'nex Machine Gun

This is a step-by-step, easy-to-follow, guide to building the simplest K'nex machine gun on the internet.

Step 1: Subassembly I

you can use the single tab end pieces instead of the doubble tabs

Step 2: Subassembly II

It looks complicated, but you really only need to connect all of the subassembly I's together.

Step 3: Subassembly III

the grey spacers can be replaced with three blue spacers depending on how many pieces you have. you can replace the K'nex Ferris Wheel motor for another one, but you may have to add more than one depending on how powerfull it is. If you do this, you will modify the design slightly.

Step 4: Subassembly VI

This is the stand for the Main gun

Step 5: Final

It should be pretty simple to connect the two previous steps.

E-mail me at hillbillyredneck@comcast when you have completed the gun. Pleez make suggestions.

Yes, gatling was the first, but a the first gatling guns were WAY to big to use with a trigger, and a handle, it used to be a cannon/chaingun weapon-_-

Chikara (author)2009-08-02

Okay... people that say this and other machine guns are Gatling guns... check the facts. A Gatling gun is a machine gun, and is hand operated, infact it was the first rapidfire weaponry. So, either way, this isn't and NEVER will be... a Gatling gun. Gatling guns have to be hand operated with a crank. Motor powered Gatling guns are actually called Miniguns, which yes, are real, motorized, army weaponry.

bighead5454 (author)Chikara2010-07-20

you are wrong a gatlinggun isnt the first rapidfire weaponary the first was an auto-loading ballista the romans designed, and used

Chikara (author)bighead54542010-07-20

It's not really rapid fire. Rapid fire, in my definition, is something that can shoot at least 10 shots /second

im tried to amke a gattling gun but i wanna attach a crank so that you can pull it back, how is it possible, i am making snowflake with green rod gears but it doesn't seem to work...

Chikara (author)knex_mepalm2009-09-29

a gatling gun? you are trying to make it spin? more detail plox :D

knex_mepalm (author)Chikara2009-09-30

So a gun in which you spin the crank and it rotates gears which pull back a ram and lets go when it is too far back and then it snaps back forward shooting the bullet, and then again and again and again

Chikara (author)knex_mepalm2009-10-02

oh, make one that isnt chain fed or mag fed, make tons of barrels and fill the ammunithion with them and a rubberband.. make a hole at one point in the front of the gun and spin the barrels, so whenever a berrel makes contact with the hole it fires, in other word, make every barrel into a miniature block gun

knex_mepalm (author)Chikara2009-10-03

"make one that isnt chain fed or mag fed" Thats what i asked, "how do i make it"

Chikara (author)knex_mepalm2009-10-06

lol well you can get innovation from this and put a handle on the end, or look around for "gatling guns" even though they are machine guns, they arent gatling guns rofl

Blackonyx2234 (author)2010-07-18

I'm actually thinking of a minigun that has barrels closer to the center to that it uses less parts (slightly). it might work but may not i just need to see some ways to spin the barrels

sensoryhouse (author)2008-01-30

CAN ANYONE EXPLAIN WHY EVERY TENTH INSTRUCTABLE IS A KNEX GUN i'm not hating it just seems like a seriously weird fetish. keep up the good work, if i happen upon some knex I might just have to build one. AHAHAHA!

knex_mepalm (author)sensoryhouse2009-09-29

Im up to 12th 2 unposted but none of them are guns...

Kaiven (author)sensoryhouse2008-02-28

because, a lot of noobs like to post knex junk, say be nice, know their stuff is bad, and leave it on instructables...

bighead5454 (author)Kaiven2009-01-08

be quiet it isnt 'knex junk' i will bet there is at least one knex gun that can knock you literally onto the ground so plz be quiey

An Villain (author)bighead54542009-04-26

i am canadian heavy cannon v1 is deadly

Kaiven (author)bighead54542009-01-08

... Do you not get the point in my message? "because, a lot of noobs like to post knex junk, say be nice, know their stuff is bad, and leave it on instructables..." I said NOOBS post JUNK not GOOD BUILDERS building JUNK. There are very nice and intuitive guns out there, and I know some can knock you down. I have a few of my own. Please learn how to understand English before posting a comment. (I said please, so it's not an offensive comment.)

It's too hard!

An Villain (author)2009-04-26

TorBomb has the easiest in my opinion

the_TRUE_LINK_OWNZ! (author)2009-03-06

my fingers hurt mmmm-hmm! but then again, i never stopped wotking on ther models today.........................................................................................................................................

sofaking (author)2008-01-23

nice what's the range on this thing? where did you get that moter?

musick_08 (author)sofaking2008-12-28

you can get them in roller coaster or ferris wheel kits

sarcastyx2 (author)2008-12-27

can u plz show us how to make the stand instead of showing us pictures of it

musick_08 (author)sarcastyx22008-12-28

It's easy you just have to go by the pictures.

yerjoking (author)2008-06-12

No and no because i'm in a mood and have no camera =3

yerjoking (author)2008-06-06

i got a knex chaingun, the actual gun is about 20 rods and connectors, except it uses someone elses bullets with like 1 or 2 pieces removed lol

kirdaiht (author)2008-04-22

mine is simpler.

Ikedog1995 (author)2008-03-15

pretty good and simple (for a machine gun) but the part that sets off the bullets is weak and just gets pushed back after 1 shot. Mabee try to fix it by using a rubber band.

Darth Trainman (author)2008-01-25

At least a Gatling gun.

deawon2 (author)2008-01-25

ran out of k'nex got already subassembly1 ,2times connected to the white connectors that are on the grey rod with the spacers and the tan clips

ojochris (author)2008-01-23

looks good, 1 question. why does it look like it is made of miniature pieces?

bruce911 (author)ojochris2008-01-24

Well it is not miniture peices because the half circles are actually red not yellow or grey. The reason it looks like that is probably from the angle he took the picture on.

ojochris (author)bruce9112008-01-24

well I knew they weren't minis, I just wondered why they looked like it.

arrow shot (author)2008-01-24

actually machine guns are the least common gun on this site....well, bulk guns such as rocket launchers and shotguns are uncommon, but snipers, handguns, and rifles are very comon

bedbugg2 (author)2008-01-24

there are SO MANY of these on the site already! havent you seen them!? we want somthing more complicated and new not somthing simple and common

PineapplebobTheGreat (author)2008-01-23

Nice, but gatling gun...
