A simple knex crossbow that uses few pieces. Many different types of ammo and modifications. Includes Flighted Crossbow Bolt simmilar to the sniper round but I did not copy KILLERK! I made it when I was 10.
Length=40 Cm Height 16 Cm
Step 1: Collecting the Materials and Constructing the Crossbow
4 light grey
1 medium strengh rubber band
3-5 smaller rubber bands
Follow the steps through the pictures
Step 2: Stringing the Crossbow
Add extra rubberbands to the trigger if the bow rubberband is too strong.
The trigger rubberbands will counter act the bow rubberbands.
Step 3: Constructing Crossbow Bolt
1 black socket
Construct the rod then tape on the paper fletching at both ends and back. The fletching size depends on the power of the crossbow. Keep testing it until it is good.
Step 4: Firing and Loading the Crossbow
This crossbow is only the basic form. You can make it smaller and also make it shoot two bolts at a time.
The bolt keeps falling out:
Put some grippy tape in the trigger area.
The Rubber band keeps jamming into the gap between the yellow and green connectors at trigger:
Also use tape, but use smooth tape.
This is my first instructable, tell me if it is good!
