A simple, ridiculously strong and powerful gun made out of K'nex. True Trigger. Not rapid fire. Build time: 35 minutes
What you need:
44 yellow semi-circle connectors
21 green connectors (not rods)
82 green rods
50 blue rods
26 white rods
6 white snowflakes
15 grey connectors (one thing-that-connects-to-other-things)
5 light grey connectors (two things-that-connect-to-other-things)
4 red connectors
2 orange connectors
1 blue/black movable connector thing (not all kits have it). A picture of this piece is below.
Step 1: Barrel
Make 6 of what's in the picture, as the barrel of the gun.
Step 2: Front Portion
It's just what's in the picture.
NOTE: The green pieces are connected to BOTH of the upper blue rods.
Step 3: Rear Portion.
Again, make what's in the picture.
Step 4: Handle
Make what's in the pictures. There are two things to make. One of them is depicted in the first two pictures, the other in the rest. In the first picture of the second object, it's inverted.
Step 5: Trigger
Pictures 1 and 2 = Trigger A
Pictures 3 and 4 = Trigger B
Picture 5 = Trigger C
Picture 6 = Trigger support (make 2)
Step 6: Bottom Attachment
Make two of the first picture, three of the second.
Step 7: Assembly
Put all six pieces of the barrel together (picture 1)
Add the front portion (picture 2)
Add the rear portion (picture 3)
Put together the handle (picture 4)
Clip on the first part of the trigger to the bottom part of the rear portion and add the handle (picture 5)
Add the second part of the trigger (picture 6)
Add the third part of the trigger (picture 7)
Add the fourth parts of the trigger to both sides (picture 8)
Clip on the first parts of the bottom handle (picture 9, inverted for the picture)
Put on the rest of the bottom handle (picture 10)
Step 8: Loading and Shooting
Put a yellow connector in between the two orange rods and the blue rod in front of it. The third prong down from the edge of the yellow piece goes in the hole of the orange connector. It should stay put. I used a connector from a different set so you could see it in the picture. It's grey.
Take a rubber band (the best ones to use are said in the next step) and put it from the two green prongs in the front (picture 2) to the space in the back of the yellow connector that you just put near the back. BE CAREFUL! Press on the orange connectors to keep the yellow piece from sliding out.
After the rubber band's on, slowly remove your hand from the orange connectors and pull the trigger!
Step 9: Tips
Rubber bands: Go to your local food store and buy some vegetables that are confined by a rubber band that says "Produce of Peru" on it. They're usually purple or something. If you can't find those, just get some rubber band off some vegetable in the produce section.
Replacing Ammunition: If the trigger seems very sensitive, replace the ammunition. Also, this gun has a huge reputation of breaking the ammo. Make sure you have a lot!
If you find anything wrong with the documentation or the gun (primarily the trigger), please tell me about it.
