About: I need... a tailor...

This is my first Instructable and it is a knex tank it is pretty powerful, I mean it.


Step 1: The Peices You Need

you will need:
  • 7 orange connectors,
  • 2 rubber bands,
  • 4 red connectors,
  • 16 purple connectors,
  • 13 blue spacers,
  • 13 blue spacers,
  • 13 green rods,
  • 11 white connectors,
  • 1 piece of tape,
  • 4 wheels,
  • 13 white rods,
  • and 3 red rods, I know it says 2 but I messed up.

Step 2: The Ram

build the ram. you need the tape on it or it will fall off when you fire it.

Step 3: The Barrel

build the barrel it fires best with the blue rods.

Step 4: The Shell

build the shell to hold the barrel.

Step 5: The Platform

build the platform, the right is the back and the left is the front.

Step 6: Put It All Together

put it all together. I have a lot of pictures to help.

Step 7: Add the Rubber Bands.

add the rubber bands as shown. now pull back the ram load in a blue rod and fire it!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Step 8: If You Want To

If you want to you can get x32 chain link, 4 red gears, and replace the two green rods in step 3 to white rods and put on x16 chain link on each side of the red wheels. :D :D

    what do u have against block trigs, huh? theyre the sturdiest and most relibale ones, and they work better than true trigs. this is revolutionary! think of all the possibilities we can do ! block triggers with wings! Block trigger on a stick! block trig alarm clocks! block triggers on block triger! the sky's the limit!

    no username is right true triggers are best but block ones are a little more compact and simple, good for small spaces..........not for a machine pistol :D

    yes that is true but which trigger breaks mre pieces THE TRUE TRIGGER i recently made a gun and was suprised tp see that after about 5 shots a piece broke then i made a block trigger fun and guess what

    dude, be quiet. If i recall... Easy Knex Pistol This pistol is easy to build. It is powerful for it's small size. This is my first instructable. This gun shoots about 25 feet. Which is also a block trigger. You made another gun for your first and only, he made something with an immaginative idea, and got a great result!


    you could make it so that if it bumps something, The ram hits the thing at hi power. That would be a "bee sting " machine. It would hurt.
