Bigfigs are like minifigs, but they are larger, and have more posing possibilities. The original design of the legs was Moko, but I modified it a little bit. NOTE: Bigfigs contain all official pieces.
Pieces:1 Full minifig, 4 lever bases, 2 lever handles, 6 round studs or 2 round bricks, 1 grill plate, 2 square studs or "teeth" pieces, 1 rubber band piece, and a harpoon piece or other small not sharp pokey object.
The fig without a gun.
Comparison to a normal minifig.
Step one: Get all of the pieces shown and assemble them
Step two: Place the levers through the grill plate and attach to the lever bases
Step three: Slide the rubber band through the hole of the minifig's torso, and out the bottom end
Step four: Using the harpoon piece, push the end of the rubber band out the other hole. (This step may take some time to do, it can be difficult)
Step five: Pull the rubber band ends out and put the minifig legs on. (Only temporary)
Step six: Put the lever base on the rubber band loop and pull it out with a harpoon piece.
Step seven: Pull the rubber band out and put the arm in place. (The rubber band should form a tight loop around the bump in the arm)(This connection is FRAGILE, so be careful)
Repeat step six and seven for the other arm
Step eight: Put the two parts together, they should look like this now...
... notice the division the rubber band creates,the back section is where the lever bases will slide into, locking the legs in place
I hope this helped you create your very own bigfig!
