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.

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.
<p>why did u cut off the old chin ? </p>
It was too short and my son's 'real' chin stuck out. Since this was 'build-on-the-fly' we had to make adjustments along the way.
<p>the link to your full build is missing. the link wont work.</p>
Hey, could you substitute the fiber glass with paper miche?
Sure, but it won't be as sturdy so you would have to be careful.
How much would you sell that costume?my gmail is chanceclarkekuzman@gmail.com
This is too near and dear to my son for me to sell. Plus it was custom made and would probably not fit anyone else correctly.
<p>Hi! I am wanting to start this project for my son, but I need to know what pattern you used on pepekura. </p>
<p>I didn't use a pattern. I referenced a couple of pictures from the internet and also the small plastic figure and just started cutting the cardboard. It was built on the fly, so to speak.</p>

Dude thank you so much
I'm using a fiberglassing resin kit that cost AU.$ 30.00
What brand of bondo did you use?
Amazing Halo armor! Great work! May I ask you how much it cost to make the whole suit? I'm planning to make my own Halo 4 suit for Halloween.
It cost me about $150 USD for bondo, hot glue, paint, fiberglass, LEDs and misc. electrical supplies. The cardboard was from old boxes.

ill post the helmant when it is done
If i gave you the material would you make it for me? and if you can how much money do you want?
hay i made the helment and just wont to no how do you make the chest pice
It'd be cool to try to make N.O.V.A. 2 armor with this method. I would if I wasn't dirt poor.
hi I&rsquo;m in the process of making my own costume but having some trouble with codpiece, legs and arms. as fiberglass is relatively expensive I'm using paper mache to cover it. I've currently finished the helmet, chestplate and lower left arm piece. i'd also like to know how to make the halo scout helmet, chest plate, shotgun and should shields.
For the cod piece I just used a strip of cardboard to wrap around my son's waist. Then I added another one that went from the front, down through his crotch, and up the back. That gave me the basic sizing. The then added details. He wore a military style web belt and the cod piece had two velcro loops fastened to it, one on either side, that we tucked under the web belt and back up to attach to the other end to hold it in place. The web belt also had two loops of 1&quot; wide web strapping that had plastic pinch-slide clips. They dangled down under the cod piece sides to hold the leg armor up. <br> <br>The Chest plate was also pretty simple. I made a flat cardboard piece that was the correct shape and size, then added detail by cutting and folding cardboard to give it the 3-d shape. The shoulder shields were done the same way. <br> <br>The scout helmet was built about the same way I made master chief's helmet. The gold face shield was a piece of a plastic laundry detergent bottle that I spray painted gold. There was a slit that I cut near the top so my son could see out of. You can kind of see in the pictures. <br> <br>The shotgun was fashioned from a plastic toy m-16. I hacked it apart and used a length of 1&quot; electrical conduit for the barrel. It was all hot-glued together and then I layered cardboard details on top. <br> <br>Sorry I don't have any pictures of the scout or shotgun build. <br> <br>Good luck.
