Introduction: K'Nex Semi-Auto

This is a gun I made in my free time, and my new hobby is making harmless and useless weapons from household junk. My first one is my K'Nex 3 round semi-automatic rubber band shooter. NOTE: this is a prototype! I know i can make it better so please leave your comments and pictures!

Step 1: Create the Frame

Look at the pictures to figure out how to make the shooting frame thing

Step 2: Make the Handle

Again, look at the pictures.

Step 3: Connect the Two

Pictures, pictures

Step 4: Conect the Two Frames

Use blue sticks to connect the frames. Look at ALL of the pictures in this step if you want to do it right.

Step 5: Make the Barrel

I forgot this step...

Step 6: Connect the Barrel

PICTURES, YOU FOOL!

Step 7: Add These Cool Things.

These things just look cool

Step 8: The Hook

Add the hook, look at the pictues.

Step 9: Loading the Gun

Place the rubber band on the hook and pull back and under the frame. Hook the first rubber band on the second barrel thing. Then load the second one on the first hook of the barrel

Step 10: Shooting

Basically, hold the hooks until you want to shoot. To shoot one, release the hook and put your finger back on the second one. To fire the next one, let go.

This is almost 7 years old, so of course it's not as good as todays guns. Back in 2006, it was one of the first k'nex guns, so don't call it a piece of junk.

Please reconsider your statement, because this was made back in 2006, where innovation was just beginning with the subject of Knex. It developed over years into greater weapons we know today, but this is like one of the original guns made out of Knex that actually work..

No. You WILL injure someone really badly/kill them if you fire KillerK's gun at a person.

well it's pretty easy to slide an orange connector upwards so i wouldnt doubt it... but it would be an accident though.

author
I_am_Canadian made it! (author)I_am_Canadian2008-10-24

You would have to tell him how to use it.

author
grevious made it! (author)grevious2008-10-25

i could, but i wouldnt because it would we too dangerous. but it coul still be an accidnet to just slide it up, it's not that hard.

Well, I made my first knex gun at 7, and it was just 8 red rods on ? white connectors ( enough to fill it) And a simple on piece block trigger , shot through windows. Then I stopped a bit, found my stash of knex in attic at 11, used for a project, and have joined instructables in april a few months after. So I beg to differ

Ok, no shame should be pointed towards him. Just because his design may be bad in your opinion doesn't mean he has to completely stop making them. Nor does it mean you should shame him. Its kind of rude.
