Knex Light Hybrid Crossbow




this is my first instructable so please be consrtuctuive with your comments and leave your is a hybrid (hybrid means a cross between to things) crossbow/sniper as it has a crossbow look and design but sights and trigger like a sniper (although most real snipers dont use block triggers).
28 blue medium rods
4 grey long rods
4 black long rods
4 long red rods
4 small white rods
1 tinys green rod
2 yellow 1/2 white circles
6 tand 1 clip connectors
17 grey 1 clip connectors
85 red 3 clip connectors
59 green 4 clip connectors
4 1 clip
ball joint connectors ( 1/2 a ornag 2 clip connector
can shoot 60-70+ feet
black (sharpened if you want ) rods as grey rods bend and snap easier.


Step 1: Crossbow Arms

crossbow arms:
pic1-make this by atatching 17 red connectors to a grey rod and sapcing them like this.
pic2-there is 11 of these. they are green connectors with a blue rod atatched.
pic3-atatch them all onto the part you made in pic1.
pic4-looks similar to the other one but its the other side so follow the steps carefully.
pic5-make 11 of these. they are green connectors with a blue rod atatched.
pic6-atatch them all to teh part you made in pic4

Step 2: Crossbow Barrel and Block Trigger

crossbow barrel and block trigger:
pic1-atatch 6 red connectors onto the two grey rods and then slide on the block trigger.then add and another 10 red connectors in the same way as the first 6.
pic2-atatch these green connectors in this spacing order.
pic3-then add these ones on the other side (don't get confused ive only turned the barrel around).

Step 3: Attatching the Arms to the Barrel

attatching the arms to the barrel:
pic1-clip the arm onto the side of the barrel making sure that the 4 blue rods are with the 4 green connectors and the 5 blue rods are with the 5 green connectors.
pic2-now attatch the other arm to the other side.

Step 4: This Is Just a Small Step

atatching a small green rod:
pic1-attatch a small green rod to the fron of the barrel*

*-the front of the barrel is the part which has four green connectors first.

Step 5: Adding the Sight

adding the sight:
pic1-add these to the front and back making sure these tan clips are in this position.
pic2-make 2 of these (1 for the front and 1 fort the back)
pic3-clip the two grey connector on each side onto the blue rods (at the fornt and back) a side on pic is next>
pic4-here is a side on pic. as you can see the grey 1 clip connectors are glipped onto the blue rods.
pic5-this is the same as pic 4 but from the other side
pic6-same again,just a different angle.
pic7-here you can clearly see both sights in place/position.

Step 6: The Back Handle

the back handle:
pic1-put 11 green connectors onto 2 red rods like this and in this spacing order.
pic2-then add these 9 red connectors like this.
pic3-do the same on the other side.
pic4-this handle then clips into place at the back (remember the back is the part with no small green rod attatched to the barrel.
pic5-this is a pic from the back of the gun to give you a better idea of where it clips in.

Step 7: The Front Handle

the front handle:
pic1-build this peice.its on a red rod.
pic2-another pic of pic1.
pic3-build this peice.
pic4-another pic of pic3.
pic5-another pic of pic3.
pic6-join the two peices together.
pic7-another pic of pic6.
pic8-attatch this handle to the barrel.
pic9-here you can see more clearly where it is atatched.
pic10-now youre almost finished this is what your gun should look like just now....i hope it dose =)

Step 8: The Elastic Band and How to Fit It

the elastic band and how to fit it:
pic1-here is a pic of the elastic band i used.The knot is not needed it was just left over from my last gun.
pic2-fit it like this.
pic3-loading the ammo and another pic of the elastic band.
pic4-another pic of the elastic band.

Step 9: Loading and Firing

loading and firing:
pic1-load the ammo (you can sharpen it if you want). black rods are stronger so try and use them.
pic2-pull the rod back and make sure the elastic band dosent ping of.
pic4-destruction from another angle.

Step 10: The Finsihed Gun

the finished gun:

    I recon it looks pretty cool. I haven't built it, but I think it might go pretty well, but if theres a trigger or whatever, take it off and just pull it back like a bow and arrow and it'll probably work better.
