Intro: Knex Crossbow

Fires up to two shots at once, and has adjustable power. This design, with less power, can also fire 'spodies at short range.

Step 1: Pieces

Rods:
yellow-14
blue-12
red-8
white-20
green-36
gray-2*

Connectors:
yellow-24
blue-4
red-19
white-6
green-6
gray-7
orange-4*

Other:
blue spacers-16
sm. wheels-2
black connecing pieces-12
rubber bands-8 or more
string-about 1 foot

*need one to make one shot*

Step 2: Connecting Pieces and Trigger

The two connecting pieces should be opposites (as shown).

Step 3: Ammo-locking Thing

Step 4: Assorted Other Pieces

The last four are used to adjust the power.

Step 5: Arms

Make two opposite arms, and tow pulleys (to be used later).

Step 6: Put Pieces Together

Step 7: Attach String and Rubber Bands

Step 8: Attach Arms and "bowstring"

The bowstring is made by connecting about 6 rubber bands together on a string, and making a loop by tying the two ends together.

Step 9: Loading the Crossbow

This may be difficult at first, so point it downrange, so to speak. Two shots can be loaded side by side.

Step 10: Adjustable Power and Sharpened Ammo

Adjusting the power is done by moving the arms forward on their hinges, and locking them in place using the four extra pieces.


A pencil sharpener easily sharpens the tip of the ammo, but the blade dulls faster.

*Note: Caution is strongly suggested when using sharpened ammo. It is not recomended to use sharp ammo on your first try, or at anything living.

*Also note: If you didn't figure the first warning out already, it is suggested that you permanently dismantle the crossbow.

    This model can shoot only one at a time. It just has the ability to shoot two or one at a time.
