I cut down and shaped the roughly 10 pieces to fit into there respective slots leaving about 1/8 inch for the material it would be covered with. The next step was to fill in the gaps with styrofoam. The dimensions for this were pulled straight from the blueprints and after an afternoons worth of work, I had skeleton frame work that looked like the body of a turret. This stuff is great because it has no grain and can be cut and sanded smooth with relative ease. My personal material of choice is MDF (medium density fiberboard) which can be picked up at any hardware store in 2x4 foot and 4x8 foot sheets. With the size decided, The first step was building the framework for the body.

The main body and arms will be hollow while all the pieces relating to the legs will be solid for strength. These durable shells will be perfect for the final turret. The best way to achieve this with the body and arm panels is to create molds and cast hollow pieces. The most important thing about this project is keeping it as light as possible. These blueprints will also make a great poster to hang on the wall with the finished project. My friend did an outstanding job adding in little extra details like the Aperture logo and other details on the blueprints. I then printed them out to scale and pulled all the measurements I would need from them as I worked through the project. I had a friend of mine, Tyler Garrison, who is a wiz with Illustrator whip me up a set of blueprints with a height of 38 inches to the top of the antennas. This way it wouldn't take up an enormous amount of space in my place. This also seemed like a great size to display it once it was finished. I decided a more reasonable height to undertake was about 36 inches. Due to the nature of the design, I decided that making one this size would be prohibitively problematic and very expensive. I got in touch with someone at Valve and they told me that the turrets in the game stand 58 inches tall. The very first step in the project was deciding how big I wanted to make the turret. Materials and Tools used are broken down for each section. A little bit more work but definitely worth the effort. Since nobody makes them I had to build one myself.

The Turrets are so adorably deadly that I had to have one of my own.

The turret for which this instructable is about is one of only two characters you interact with in the entire game, the other being GLaDOS. Hopefully there will be a lot of information that you can pull out of this and use for all kinds of different projects.įor those that are unfamiliar with Portal, It is a fantastic puzzle game made by a studio called Valve that requires you to use two portals to solve all kinds of different puzzles. This is a fairly in depth project that will cover every stage of construction and all the techniques I used along the way. In this Instructable I'm going to show you how I went about building my very own life size talking Portal Turret from start to finish.
