Knex Mini Bow





Introduction: Knex Mini Bow

For my first instructable I decided to make a mini knex bow. This bow does not require a lot of pieces and is way more powerfull than I expected

Step 1: Step1: Very Simple

Make theese, if for some reason you can't tell there are eight of theese.

Step 2: Step2: Yet Again, Very Simple

Step 3: Step3

Sorry for bad pic but, I think you can figure it out.

Step 4: Step4

Place ruberband around one of the pullies, as this will be diffucult but possible later on.

Step 5: Step5: Almost Done

Put theese together so you get this,(see below)

Step 6: Step6: the Final Touches

Make this. (3 blue spacers = 1 grey) also the green rods are the same as red rods.

Step 7: Step7:done

Attach what you made in step 6.

Step 8: Step8: Loading and Firing!!!!!!!

When you load push the grey rod inbetween the orange and brown connectors in the middle. I would suggest cutting a slit in the end of the grey rod (ammo) but, be careful as shown in pic2,ouch that hurt my finger. When your done it should look like pic3 when loaded.

    cool! but when firing you have to place it properly or else you will hurt your self

    good job. i like the look of the whole thing. generly bows are more powerful because of the shorter berral and no need for a ram.

    Because... Direct transfer from rubber band to projectile instead of rubberband to a ram then to the projectile.

    Actually, when a large object hits a small object, the small object will travel faster than the large object was initially moving. So using a firing pin will shoot harder with a well-made gun (unless the bullets are bigger than the firing pin).

    actually the ram makes it go shorter i have theoretical and practical proof because energy is lost in the transfer from the ram to the bullet in the form of sound and heat which is also lost from the ram traveling down the barrel. this is the practical proof, think of any slingshot mech gun such as the sr-v1+v2 the sipriani rifle they have good range but a gun with a barrel and ram of the same size will go shorter. but i do admire your reasoning oodalumps.

    An intelligent response from an Instructables Knexer? I thought it was impossible. You are right that firing pin guns are inefficient. So I guess one could argue for both sides. It depends on the gun. But generally a slingshot will shoot large ammo better, and a firing pin will shoot small ammo better.

    who thinks i should post my full size bow?
