Mean Green KNEX Machine Spider




About: Just Your Average 13 year old DooM Fan

(NOTE: This KNEX gun is VERY powerful)

Yet this is my second instructable but my first KNEX.

And just to keep in mind...don't be fooled by the size of
this thing because it is proven very powerful.

Sorry if the picture quality is not the best in the world.

(Thanks to cowscankill for the spider name!)

Step 1: Getting Started...

Here are the KNEX pieces you will be needing...

Green Jigsaws - 10
yellow/onix rods - 2
yellow connecters - 1
black/rod connecters - 8
white connecters - 2
rudderband - 1
small rods - 6

(NOTE: Different colors dont mean anything!)

Step 2: Setting Up the Base...

You will need...

8 Green Jigsaws
All black connecters/rods
both yellow/onix rods,

just look in the picture on how to put it together.

Step 3: Putting Together the Base...

You will need...

4 green rods

connect the 2 base parts together shown in the picture.

Step 4: Connecting the Front End...

you will need...

2 gray connecters,
2 green/black rods,
2 Green Jigsaws
1 yellow connecter,

connect them as shown in the picture...

Step 5: Connecting the Rubberband...

You will need...

1 rubberband(Duh!)

connect the rubberband as shown in the pictures...

Step 6: Setting Up to Fire...

Place a gray rod inside the yellow connecter and pull it back until
it touches the rubberband. pull the rubberband back while still holding the gray rod. pull it back far enough until the gray rod's
other end touches the yellow connecter. let go of the rubberband and the gray rod and the gray rod should fly a very long distance.

    Also, I haven't found it to be that powerful.
    Kind of interesting shot, though.

    I've also done something so I can shoot a longer rod with an orange/brown piece on the end to be able to pull back more.
    Kind of simpler to do this for people using multiple, smaller bands.
