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!

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

There are two...

and by the way, if you don't wanna be flagged as a noob, get a profile pic.

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

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

RMConstruction (author) in reply to wwhittOct 13, 2011. 12:51 PM

Doubt either are possible...

How many green rods does it use?

bighead5454 says: Jul 21, 2011. 1:03 AM

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) in reply to bighead5454Jul 21, 2011. 10:47 AM

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

bighead5454 in reply to RMConstructionJul 21, 2011. 11:50 AM

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) in reply to bighead5454Jul 21, 2011. 4:39 PM

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.

bighead5454 in reply to RMConstructionJul 21, 2011. 9:10 PM

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)

bighead5454 in reply to RMConstructionJul 21, 2011. 9:04 PM

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) in reply to kwintisolo12234Mar 13, 2011. 3:13 AM

Do you know how old this 'ible is?!

jackojack12 says: Mar 2, 2011. 2:06 AM

Could u build it with one cog?

RMConstruction (author) in reply to jackojack12Mar 2, 2011. 7:35 AM

Nope.

jerrywu123456789123456789 says: Feb 6, 2011. 6:34 PM

jerrywu123456789123456789 says: Feb 6, 2011. 6:31 PM

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

MandH says: Nov 29, 2010. 5:04 PM

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.

ryry2011 says: Nov 27, 2010. 6:46 AM

what does it fire

x-treme says: Nov 22, 2010. 8:10 AM

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.
