Introduction: RMConstruction's Knex Minigun, V2.0

Hi all. i have been studying the vast collecion of minigun pics availible on the net, and the collection of knex miniguns. I believe this is and will be the 1st Knex Minigun instructable (not slideshow). I wanted to make it as realistic as possible, but realised that wasn't 100% possible. Actual Minigun barells are only connecred at one point, but with knex, you would need two points. I took this into account, and eventually decided to connect the handle and barell, which gave a firm base to add the main 'shell' of the gun. If your still reading this, you're probably getting bored. Let's get into pros and cons before ya' decide to just skip.....

PROS
Top handle
Angled back handle (comfortable)
Octapod... aka stand... (not tripod, is an octagon)
Shoots from a chain

Cons
Octapod pivot sometimes snaps (rarely, but happens)
Range varies



Ok. Were ready to start. This is a heck of a project!

Step 1: Firing System

Building the 'boxy thing that goes on the side'
The chain puller basically...

Step 2: Odds N' Ends

Some lil' thigs before we get to the complicated part.

Step 3: Main Shell

The main section of the gun, which pretty much holds it all together.

Step 4: Main Arm/support Thingy. Do I Say Thingy Too Much?!?!?!?

The support arm, connecting the handle with the barrel end. Features a lot of repeating repeating repeating repeating repeating repeating repeating repeating patterns patterns patterns patterns patterns patterns......

Step 5: Back Handle

The back handle & arm assembly.

Step 6: Barell

The barell, fairly simple.

Step 7: Main Gun Assembly

The assembly of the parts you've made already. No, I havent forgotten the chain or Octapod.

Step 8: Chain

Well done! You've completed the main gun! Now for the Chain... And loading....

Step 9: Octapod

Stand for the whole thing. I call it an Octapod as the base is an octagon.

Step 10: COMPLETE!!!!!!!!

Well done! you now have a knex minigun to wreak havoc with! MWUHAHAHAHAHAHAHA!!!!

The main shell is confusing me,how many segments do you make?

poo2thegeek (author)2010-06-04

author
jackatronix (author)poo2thegeek2011-04-01

Yeh and me, it is quite confusing when there is no list of parts etc, but other than that it is freaking awesome!!!!!!!

Oh no. I now have a huge temptation to build this.

Hey can somebody post a firing video and a part list??

author
RMConstruction (author)wwhitt2011-10-13

Doubt either are possible...

How many green rods does it use?

great gun, fun to use, but the octopod is flimsy and keeps breaking on me-probably something i did wrong, but besides that, its awesome

author

Thanks :) I used Cyber K'nex for added strength on the Octopod...

author

hey, i have a problem with it
although you have scrapped it already, i was thinking you may be able to help

when i put in a chain loaded and everything, it only fire the first three or so shots before the chain comes off the gear
i removed the wheel and it helped a little bit, but did you eery have this problem when you had the gun?

author

Does it fall into the gun or out of it? If it's out, the motor may be struggling to pull the weight and will jog the gears in its efforts. Try changing the batteries, or ger a blender ;)

If it's into the gun, the last couple of shots usually fall through without the motor's help because of the weight.

author

sorry, but nevermind, i hadnt put enough lead for the chain to get a good grip (i only have about a foot of chain) so it was just coming off

thanks for replying tho

wow, just asking for help then figuring out what was wrong after you replied, trying to help makes me feel terrible

well, thanks i guess
(i cant really say anything without seeming like a jerk)

author

neither

it just falls off the gear, towards the front of the gun even when it is held out straight or supported by a table

i found that a slower motor actually helped, but not much

can you add a video to see how it shoots?

author

Do you know how old this 'ible is?!

author
jackojack12 (author)2011-03-02

Could u build it with one cog?

author

Nope.

author

and why not use a green connector instead

author

me too

author
RMConstruction (author)2010-12-16

Look at the pictures. Would help if you were more specific!

author
RMConstruction (author)2010-12-16

The handle.

author
RMConstruction (author)2010-12-14

Oh? How did it turn out? Did it fire well?

author
MandH (author)2010-11-29

Pretty Nice. I like how you did not fancy it all up like a lot of K'nex builders do. I think it just wastes time to make it fancy.

author
ryry2011 (author)2010-11-27

what does it fire

author
x-treme (author)2010-11-22

Whoa!
This is amazing!

Even though I don't have enough pieces to build it, If I did, I defiantly would make it!
I'll try to make a smaller version of it and post it.

5*

There are many guns that use the same mechanism. Supapoopa recently posted his take on it I think.

AgentCWG (author)2010-07-18

Is it possible to build this without the whopping long bit on the bottom? I don't hav emany yellow connectors left.

author
RMConstruction (author)AgentCWG2010-07-21

Yes, actually. I'll get you a link to somebody else's mod, because of the same reason.

author
bighead5454 (author)2010-07-20

can i use your firing system for a gun im making?

author
redroo90 (author)2009-08-10

I don't have that motor,so im going to try useing a different one. i will tell u if it works.

author
RMConstruction (author)redroo902009-08-10

OK :) Good luck!

author

hey if you took off the barrels, rigged some gears to another cyberknex motor, and rigged up the motion sensor you may be able to make an Auto-turret

author
stubbopolis (author)redroo902010-06-19
