Introduction: K'nex Rubberband Repeat Gun

Picture of K'nex Rubberband Repeat Gun

this is a k'nex gun i found on irwinner's site: here. all design credits go to him, this is just the in-between steps (i think). also, check out my other gun mods. these include a sniper with this base.

Step 1: Make Parts

Sry i didnt like it, the instructions are too blurry at the end and i cant see anything. if you can make it better it would be nice. and work on making it more sturdy. cause the whole thing falls apart when i put a rubberband.

First, this was published over four years ago.
Second, these photos are MUCH less blurry than a large portion of k'nex instructables on this site, may I suggest glasses? This may sound harsh, but I do believe "I can't see anything" is COMPLETELY ridiculous.
Third, if it falls apart when you use one rubberband, you built it wrong. Last time I had this constructed from these very instructions I could load more than 10 on it, without issue.

it depends on what rubberbands you use, if they're too big, there will be no tension, but if too small, they wont stretch far enough. play around with a few sizes until it works well.

fgfhf (author)2008-02-08

i really liked the pictures they where easy to look at unlike the other ones

originalwynne (author)2008-02-03

dont mean to sound like a total NOOB but is a rubberband gun a gun that fires rubberbands or a gun that uses rubberbands to fire other stuff like knex rods?

cobra (author)originalwynne2008-02-03

they can do both.

gunmanx (author)2007-06-09

hey wen ever i fire this the rubber bands get stuck and they juz stay on the thing and dont fire but wen i fire my last rubber band they all come out at once wat do i do to stop this

agent harmsy (author)gunmanx2007-06-16

you need to load from the back, otherwise that will happen. to put more on, pull the back piece down while holding the spindle and move back to expose the unloaded rods.

it slips under pressure

baney (author)2007-05-20

Sweet gun man, it took forever to build but it was nice. The only problem with he gun isnt realy a problem... the fireing lock isn't very strong, so if you hold the fighering thing still and keep adding rubber-bands and let go its -fully automatic-!

knex r us (author)2007-04-22

I think that this is a really kool gun that is awesome because it has a basic design which means u can add lots of mods like a larger stock. now i am tryiong to submit an instructable on mods for this gun. it will be up as soon as i get a cable for my digi camera

gunmanx (author)2007-02-18

DIRTYSHOTZZ (author)2007-01-18

Hey yo Ive posted a reloading knex target. Check it out under my instructables. Tell me what you think!

hobo lord (author)2006-11-14

Oh it is the semi auto rubber band gun. I also doubled the locking mechanism because it always slipped off under high tension

Knex Lego Maniac (author)2006-11-13

NEW REDESIGNED RAM a vid will be up in the next couple of days to demonstrate how to load the ram w/ rubber bands and operate also a SNEAK PEAK at my SNIPER BULLET in action! check it out! thanks, spread the good news

hobo lord (author)2006-10-19

I combibned the basic knex pistl with this gun and made a much simperler design. It uses a lot less pieces

Jaxsun (author)hobo lord2006-11-12

whats the basic knex pistol?

Jaxsun (author)2006-11-12

i have problems with it shooting more than one band at a time

hobo lord (author)2006-10-20

I havent tested it officially but i say with the best rubber band about 20-25 feet

How far does it shoot? You know me

irwinner (author)2006-10-09

agent harmsy (author)irwinner2006-10-14
