Today's project is the Weighted Companion Cube from Portal, and in honor of the fact that Portal 2 is on it's way I would like to present you with my instructable on how to make a Weighted Companion Cube.  For this project you will need a somewhat moderate skill at carpentry and a significant amount of familiarity with your Tablesaw, Router, and a chisel.

****WORD OF CAUTION AND DISCLAIMER********
This project puts you in very close proximity to a lot of sharp blades etc.  Proper safety measures as well as safety equipment should be observed and worn at ALL times.  Basically, if you lose a finger it's on you.  So here we go.  

Tool List:
10" or greater Table Saw
Router with a 45 degree chamfer bit (I prefer Diablo myself but you pick)
Shaper Table with a v-groove bit
Drill Press 
3-1/2" Holesaw
1" Holesaw
5/8" Hair pin nailer (check Harbor Freight tools it's indispensible if you are a carpenter!)


Materials List:
1 piece of 2'X4'X1/2" Medium Density Fiberboard (MDF)
1 Piece of 2'X4'X1/4" Medium Density Fiberboard (MDF)

Step 1Let the cutting begin!!!!!!

Let the cutting begin!!!!!!
The cube itself is 5" by 5" finished measurement.  First things first, rip a 5" strip out of your 1/2" sheet and cut that strip into six 5"x5" squares.  Mark center on each of the squares and grab your 1/4" stock.  Second rip a 4" strip out of your 1/4" piece of MDF and cut into 4"X4" squares.  These will be your interior cube and believe me it makes the whole process a lot neater.  You will have scrap of both left over but save the 1/4" scrap for the emblems at the end.  At this point you should have six (6) 5"X5"X1/2" squares and six (6) 4"X4"X1/4" squares

Great instructable, I used this as a base for a 12" one for my Sons Birthday, Used a swivel head lathe for the round bits (including the glued up sides, scary stuff) and 132 passes on the table saw at 45 degrees for the facets etc. Thanks for the guide. My 6 year old is over the moon with it.

Ended up with:

Any chance you could make an instructable for how to make the newer portal 2 companion cube? most of it would be similar, but there is no piece sticking out of it with a heart. instead there are some indents, etc...

I'm going to make this, and it will be so much fun!

I am very much impressed. :) I lack proper tools to do this however. Perhaps my father can assist.

If not, purchase might be considered. This really is the most impressive looking one I've seen. <3
