Introduction: Lego Portal Turret

These are the instructions for my popular design of a laser turret from Portal. It's all Lego; you won't need any other materials to make this nice display piece.

Step 1: Parts Needed

Here are the parts you'll need. You may have some, most, or all of these in your own collection; if not, you can get them from Bricklink.com (or Lego's Pick-A-Brick , but they tend to be much more expensive, if somewhat easier). Part names may be different between Bricklink and Pick-A-Brick.

An Excel sheet of the parts with links and more information is attached.

Step 2: Step 1

Onto the build! I'll add hints down here for the Lego-illiterate. ;)

Step 3: Step 2

Yes, the tiles are supposed to swing back and forth loosely here. They will be secured later.

Step 4: Step 3

Unlike the previous step's bricks, these have studs (the knobby things) on all four vertical sides -- they are often called "travis bricks". This step ties the whole assembly thus far into one piece.

Step 5: Step 4


Step 6: Step 5


Step 7: Step 6

None of the non-white pieces' colors here matter much; they won't be very visible.

Step 8: Step 7

Notice that you do the same thing on the other side.

Step 9: Step 8


Step 10: Step 9


Step 11: Step 10


Step 12: Step 11

This connection may be a little loose; using newer clips or gently squeezing the clips before attaching the brackets can help.

Step 13: Step 12

The 1x1 slopes are called "cheese slopes", one of my favorite parts.

Step 14: Step 13


Step 15: Step 14

This one can be a bit tricky; the bases of the sticks, when put in together, should stick tight in the red plate.

Step 16: Step 15

Fit the previous assembly in the 1/2-plate gap that goes around the body. Try to fit the balls of the lever handles in the gap in the middle; this may take several tries. Once they're in, gently squeeze the body to slightly shrink the gap, to hold the eye in place.

Step 17: Step 16

Did you get the eye in? Great!

Step 18: Step 17


Step 19: Step 18

The tap's top can move around a bit within the slope, making for some nice angles.

Step 20: Step 19

Depending on the parts you have, you may have to pull the hands out of your minifigs' arms. It's okay, they won't mind.

Step 21: Step 20


Step 22: You're Done!

Once you've adjusted the legs to your liking, congratulations! You now have your very own Portal turret. I recommend using it only as a display trinket; it won't hold up to much play.

Step 23: Credits

These instructions were built in LDraw/MLCad, then screencapped in LDView and edited in Photoshop Elements.

Step 24: ...But What About the Laser?

Oh, right. You're wondering how I achieved the laser in my photograph? Don't worry, your turret won't actually kill you.

Materials needed for laser effect:
Laser light (warning: don't shine in anyone's eyes, etc.)
Misting humidifier or something else that creates a mist or fog

Step 1: Shine laser into turret's eye (it's okay, he can't be blinded)

Step 2: Fog up the area with the humidifier to make the laser visible

Step 3: Take picture


Here's my setup:
