I designed this arm gun about a year ago, it has eight barrels that hold up to 10 rubberbands each, I am going to tell you right now that I am not going to post this version in full instructions. I have doubled my knex amount since then and can make many needed improvements. but that will have to wait a month or two.

 =O....... holy hell.. how big id that thing?!?!?!?!?!?!?!?!?!... ITS FREAKIN HUGE!!
matstermind (author) in reply to Ben_the_BuilderNov 28, 2009. 6:51 AM
if i remember correctly, it weighed 8 pounds, was 20 inches long, and 8 inches in diameter. but that's just my best guess, its not exact. i will be working on version 2 soon, i got distracted from building it before.

you said 8 barrels that hold 10 rubber bands... Do you mean 8 barrels that hold 10 ammo each? If so, this is awesome! Like an arm shotgun :p
heatblast in reply to arrow shotJul 11, 2009. 11:20 AM
to me it looks alot like the firestorm cannon from turok 2: seeds of evil
matstermind (author) in reply to heatblastJul 11, 2009. 11:32 AM
never played it, or seen the gun
heatblast in reply to matstermindJul 12, 2009. 10:32 AM
i used to play it alot, when i wasn't as grown up as i am now... that was several years ago. but yeah, this thing looks alot like it. if you have an n64 youll know what game im talking about. oh yeah LOL, i hope you realize you're talking to a pyronite :)
matstermind (author) in reply to heatblastJul 12, 2009. 10:46 AM
i have had every game for the nintendo 64 emulator that i can find for while, and i don't know what your talking about, i hope you realize your talking to a computer geek :)
heatblast in reply to matstermindJul 12, 2009. 11:08 AM
1. i mentioned the game in my previous comment. 2. if you claim you have every then it should be somewhere in your pile, and 3. a pyronite is living fire of coarse :-p
matstermind (author) in reply to heatblastJul 12, 2009. 11:11 AM
1. i know, 2. yes i have it, 3. i know
heatblast in reply to matstermindJul 12, 2009. 11:18 AM
that's good to hear :) i don't think we've been introduced, you new here? i've been here awhile, 2 years to say the least.
matstermind (author) in reply to heatblastJul 12, 2009. 1:13 PM
i've been here about a year an a half
heatblast in reply to matstermindJul 18, 2009. 2:32 PM
killerk has been here longer than any of us. sorry for the late reply, ive been busy.
matstermind (author) in reply to heatblastJul 19, 2009. 8:27 AM
a lot of people have been here longer than a lot of people
heatblast in reply to matstermindJul 22, 2009. 12:35 PM
i couldn't agree with you more... some have been here forever. others, only a couple of years... yet again another late reply,you probably think it's a habbit... sorry man, it's my sisters computer, so i hardly ever get to use it, only if i'm lucky enough... oh yeah my birthday's coming... i'll be 18 soon, so feel free to celebrate with me. your new friend, heatblast
matstermind (author) in reply to heatblastJul 22, 2009. 1:20 PM
you did not reply late, I've waited nine months before someone replied to one of my comment questions.
heatblast in reply to matstermindJul 23, 2009. 12:49 PM
your arm gun looks interesting... though it might need some reinforcement .anyway, i thought i'd give you the heads up man... and wish you good luck with the instructable. :)
matstermind (author) in reply to heatblastJul 23, 2009. 1:46 PM
thanks, the only reinforcement it needs is on the front of the gun barrels, and where you hold onto it inside the gun
heatblast in reply to matstermindAug 8, 2009. 8:02 AM
anytime, :)
matstermind (author) in reply to heatblastAug 9, 2009. 6:33 PM
?

mastermind says: thanks, the only reinforcement it needs is on the front of the gun barrels, and where you hold onto it inside the gun. sound familiar ?
matstermind (author) in reply to heatblastAug 12, 2009. 9:27 PM
it's my comment above, what did you mean by "anytime"?
heatblast in reply to matstermindAug 13, 2009. 5:11 PM
means your welcome. :p
matstermind (author) in reply to heatblastAug 13, 2009. 5:18 PM
oh, thanks.
heatblast in reply to matstermindAug 19, 2009. 6:08 PM
no problem.....
matstermind (author) in reply to arrow shotMay 21, 2009. 5:25 PM
they don't all shoot at the same time. it's more like eight semiauto rubberband guns attached together
knexxpro says: Jul 22, 2009. 8:42 AM
Im thinking " Hmm ... If I put this on, will I look like MegaMan ? " Lol.
