Cardboard/Fiberglass Halo 3 inspired Master Chief Costume

Cardboard/Fiberglass Halo 3 inspired Master Chief Costume
I made a complete Halo 3 Master Chief Halloween costume for my Son out of cardboard and fiberglass. I started with the helmet. Here are the steps I followed. A small action figure and images found on the internet were used as patterns. The proportions and details may not meet the scrutiny of many 'super fans' but I'm sure my ten year old will like it just fine.

He has two Spartan weapons, a Sniper Rifle and an M6G Magnum

I have only detailed the build of the helmet here but you can see
the Complete Build here.

October 27th 2009 - I have just added pictures of the new helmet, chest plate, should shields and shotgun I built to modify the Master Chief costume from last year into a Halo Scout for this year.

Step 1

I used thinner corrugated cardboard for the helmet. A bucket was made which was used as a base to build from. I measured from the top of my Son's head to the base of his skull where it meets the neck. I cut a 7" tall piece of cardboard and wrapped it around his head to get the right size and taped it to make an oval tube.

The first photo shows how I traced the outline on another piece and then drew about a 1" larger outline. I made sure both halves of the oval lid were symmetrical. I 'tabbed' the oval as seen in the second photo to fit inside the tube.

The last photo shows the flat piece hot glued to make the 'bucket'. Center lines drawn for reference.

DUDE! REALLY HOW DID YOU MAKE THOSE BOOTS!
May 11, 2011. 2:39 PMender23 says:
DUDE! Awesome! but I noticed on the complete build you highlighted that you didn't have the pictures or instructions on the m6g magnum or the gloves and boots. Do you think you could add that and add some instructions to the; chest plat, arms and legs, guns, lighting, and gloves and boots. PLEEEEAAAASE MAN PLEASE I'm making this for the comic conn this year and I really want to make it.
