Picture of RMConstruction's Knex Minigun, V2.0
PICT0265.JPG
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...

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

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
RMConstruction (author)  bighead54544 years ago
Thanks :) I used Cyber K'nex for added strength on the Octopod...
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?
RMConstruction (author)  bighead54544 years ago
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.
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)
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?

RMConstruction (author)  jackojack124 years ago

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.

what does it fire
x-treme4 years ago
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.

Is it possible to build this without the whopping long bit on the bottom? I don't hav emany yellow connectors left.
RMConstruction (author)  AgentCWG5 years ago
Yes, actually. I'll get you a link to somebody else's mod, because of the same reason.
