Introduction: Worlds Smallest Firing Knex Gun

Picture of Worlds Smallest Firing Knex Gun

i made this when i was bored, i am not 100% sure that this is the worlds smallest so please post if it is not ( it only uses 4 pieces)

Step 1: What You Need

Picture of What You Need

this is what you need:
1 white conector (8 slots)
1 blue rod
1 black rod/ conector

Step 2: Adding Ruberband

Picture of Adding Ruberband

make the ruberband only go over the hole once, with the rest keep wrapping it round somewere away from the hole

Step 3: Add Blue Rod

Picture of Add Blue Rod

push the blue rod into the hole on the side were the rubberband isnt covering up

Step 4: Add Black Connector/rod

Picture of Add Black Connector/rod

push it on the end of the blue rod which has been through the hole and should have a bit of elastic on the end of it

Step 5: Firing the Gun

Picture of Firing the Gun

to fire the gun, hold onto the black rod/connect and pull it back, this should force the blue rod to get forced out of the hole, if the rubberband is weak try a yellow rod

well, it's been over a year, are you going to post it?

sammyb (author)The Jamalam2008-06-21

i have already posted it

The Jamalam (author)sammyb2008-06-21

it says you haven't posted anything under your name. Can you post a link?

sammyb (author)The Jamalam2008-06-21

I posted it at the very beginning when knex guns were first around but Instructables deleted it because it got to old.

Bartboy (author)sammyb2008-07-22

yeah...right, Along with your 1000 shots a second fully auto knex gun with a clip of 10000000000 pieces .

HOLY "bleep" man He must be good.

sammyb (author)Bartboy2008-07-23

What?, an 8 shot pump action rifle is not revoloutionary, I was not even boasting. Think before you type next time.

Bartboy (author)sammyb2008-07-23

They don't delete stuff for being old.

including ammo or not? because i made a peashooter type thing (fires actual knex pieces) out of 2 pieces including ammo.

I made a very mini bow with 1 knex piece and rubberband excluding ammo.

oh, mine uses no rubber bands.

Surely you'd need one for apt power?

no, just rubber bands.

michoi (author)An Villain2009-06-08

ya three pieces triger body and the ammo

An Villain (author)michoi2009-06-09

in mine the ammo is the trigger and it is true-ish.

Bartboy (author)2008-09-06

Have you seen the "be nice" comment policy Id be careful if I were you. Stevolution says: K'nex guns rule, K'nex instructables rule and this rules.

this is my first instructable, posted it on here so that people that just want to make a knex gun in a few secounds they can, it can fire 15ft woth the right rubber band, sometimes more

JJrulz (author)2007-03-15

do u count ammo and rubber bands as pieces if not i reckon i could make 1 usin 3 peices( not yet tho, im still in the process of actually getting some knex)

david_troub (author)JJrulz2007-03-15

yes i counted the amo and the rubberband as pieces

crestind (author)2007-03-15

I must say- severely lacking in all aspects. This didn't even need instructions.

Whaleman (author)2007-03-14

Once again, what I said earlier. Please regard it seriously.

Kaiven (author)2007-03-14

bunduk (author)2007-03-14
