Introduction: Bolt Action Knex Gun

this is a small basic knex gun that has some never before seen features.
it is bolt action with a (i call it a percussion cap) that when struck by the ram it will shoot whatever
is in the barrel out with force

Step 1: Parts List

you will need these parts to make this gun

16 gray pieces
5 orange pieces
2 yellow pieces
1 lime green piece
1 knex hand
1 blue rod
1 yellow rod
1 black rod
and the elastic/s of your choice

Step 2: Make the Barrel

start by attaching one orange piece to the end of the black rod and then add 8 gray pieces right behind the orange piece. next take one gray piece and turn it sideways and attach it.
now put the knex hand in the end of the barrel and attach the lime green piece and a gray
piece right after it.

Step 3: Make Hand Hold and Trigger

start by attaching one orange piece just like the other gray piece in the last step.
next take 2 gray peices and attach them behind the hand hold. after that take a orange piece a slide it down the black rod to the gray pieces then attach a gray piece behind the trigger.

Step 4: Make the Ram

take the yellow rod and put a orange piece on one end and attach a gray piece infront of it

Step 5: Make Rear Sight and Slide

take the half finished gun and add one more gray piece to the other gray piece behind the trigger.
then take 1 yellow piece and attach on the bottom of the gun and add a orange piece behind it.
take another yellow piece and a gray piece and clip them each other. take this piece and attach it to the black rod

Step 6: Insert Ram Into Gun

slide the ram into the back of the gun

Step 7: Add Elastics

add the elastics as shown in the picture

Step 8: Add Slide Elastic

wrap elastic around this area. go to next step for next picture

Step 9: Slide Elastic Part 2

now loop the elastic around the front of the gun and wrap around the gray piece thats in front of the hand hold

Step 10: Done

there you made it and now you can fire it.

pull the slide back like this
and put something in the barrel and pull the trigger

This is actually a very good concept. I quite like it :)

I don't have either the lime green piece or the black thingajigger(no not the rod...the other thing), can I still make this?

author

Hahahaha. Yes, yes I was. I've moved on to more challenging mediums since. I'm not anti-knex - just anti-bad ible. ;)

There is no doubt in my mind that you've given up on this, but yes and no. The lime green piece can be replaced by a gray one-slot clip. The black thingajigger isn't needed, but it won't work the way it was intended.

author

Hahahaha. Yes, I did give up about two years ago. Thanks for the reply though!

i tried making one like that before i saw this instructable. It sucked in every way it's possible to suck, and in some that are essentially IMpossible it had a reload time of something like 4 days, and i can't possibly guess about range and power because i only fired it twice

a few months ago i made a magnum/shotgun/grappling gun and it was so powerful the firing pin would come off and shoot out with the ammo.It used 12 rubber bands

author
Nyanman made it!(author)2008-06-07

i think somone should totally build a big rifle one of these with the firing pin the size of a grey peice! that would hurt! oh and great gun. my bolt wont fly back on its own tho. i put a orange connector w/ a blue rod for the bolt handle on mine.

A really cool thing to do is put a drill bit in the gun and fire it, it is deadly and it makes a cool sound

author
the+deadly+pigeon made it!(author)2007-06-06

my gun broke as soon as i fired it but it is pretty cool.

author
JR-9979 made it!(author)2007-04-04

have you made it or just looking at it. if the projectile is touching the black Y piece in any way it will fire. i actuly made this to fire shotgun style firing only birdshot and i needed a way to contain the shot as i was breaking parts just pulling back a rod and pouring the shot in and firing so i thought this gun design up.

author
I+make+cool+crafts made it!(author)2007-04-04

how does this thing shoot? the black y peice stops it frop shooting the blue rod.

thats one of its problems that i'll be fixing soon by puting a balljoint connector in place of the black knex hand and adding more elastic bands.

author

Mine only shoots about 2ft

author
Aeshir made it!(author)2007-03-04

I made this but I can only get it to fire the little purple/blue rods. The other ones don't do anything. I don't know what's wrong with it.

bolt action is when you pull the bolt back then twist it to the side and push it back again. just like a door bolt

author
Ryan+Fanshaw made it!(author)2007-03-04

author
Vertigo666 made it!(author)2007-03-02
