Step 5: Make It STRONG - Outside

Wow! has it really been several days of cutting, folding, and glueing!?  All done? No left over parts?

Cool! So now you have a Halo ODST helmet made out of paper. If done right, your paper model should be strong enough for you to put it on for a test fitting. If your cuts were precise, your folds sharp and your glueing is clean then you should have a very good looking bucket.

But, it's still just paper. we need to make it stronger.

This is a two part process and there are several ways to do things. I will describe the different common methods I have tried.

The first step is to strengthen and seal/waterproof the outside. This is done by applying a thin coat of glue or resin on the outside. We want a THIN, even coat. Too much and you could loose the fine details of the pepakura or colapse the model.

The three most common ways to do this is:
1. Brush on polyester resin.
2. Brush on epoxy resin
3. Brush on wood glue.

Why three methods? Well, it really depends on two factors, your working environment and your budget. 

1. Polyester resin is cheap. a quart cost $12 at Wal***t. Problem is polyester resin puts out lots of deadly fumes. You have to wear a respirator mask and you will stink up the surrounding area. Not great if you live in an apartment. Also not good if the people around you (small children, pregnant spouse, elderly) have to stay away from dangerous chemicals.

2. Epoxy resin. General use fiberglassing EPOXY works great. It has very low odor (smells mildly like popcorn), not as toxic, and is strong. Biggest issue is that it is expensive. A quart will run about $25.

3. Wood Glue is also cheap and is available everywhere. It is non-toxic. Has no odor. Requires no mixing of chemicals. You just brush it on and let it dry. Only issue with it is that it is not as strong. Also, becuase it is water based, too much of it may warp your helmet. Once dry, it is waterproof. This is the method I used for the the helmet in this example.

** Note: I have used all three methods above.  There is a fourth method called AquaResin. Never tried it. ***
<p>is it strong enought to withstand airsoft and paintball?</p>
<p>no. airsoft - maybe. paintball, no. the ammo has too much mass</p>
<p>are you able to trace what you cut out on to eva foam or craft foam to avoid all of the resin and strengthening of the card paper? I have 2 months to make mark IV iron man, soooo... </p>
<p>I found some great armors made out of foam. Mostly is was for Mass Effect armor, but the looks was incredible. What was used was the black/charcoal square exercise/workshop mats. Google that method. It seems to work. You will need a heat gun.</p>
Do you have the exact link for the place you got the visor from?
theres actually a foam method shown on youtube (Backyard FX Sci-fi Armor build) in which they use a foam mat to create what looks like plate metal armor like the halo armor
<p>That works, but isn't as strong, releases toxic fumes when thermomolded, and requires even more work...</p>
I'm in the army and don't have time to build a suit anyone want to make some money?
Just flagged on accident sorry
How many of these have you done?
very good and very detailed, the very best one i've seen. i've learned more from this than i have from from all the other sites i've been on altogether. good job, thanks
AWSOME!!!, but im not bothered making it gonna go buy it instdead(helmet) and i dont get how paper can turn into that. Any way thanks, its AWSOME!!!!
If you coat the card in a layer of petroleum jelly, leave overnight and wipe off, you have waterproof card you could coat with PVA glue/woodworker's glue and the card won't absorb any of the water. When I first started on my helmet two years ago, I assembled it with undiluted PVA glue instead of nitrocellulose glue and it warped. Nitrocellulose isn't the best solution either, when I applied too much, it would bead on the outside of the helmet and leave a hard residue that can't be removed until detailing. But it dries faster than PVA glue so I went with that.<br><br>I found that rubber cement worked the best for this. Glue every tab, leave dry, then press together. It's not permanent but it can be repositioned until you glue it together with PVA glue.<br><br>Hope this helps!
I like the rubber cement idea.
I'm glad this helps.<br><br>According to the bottle, if you let dry and press together, it's a temporary bond, but if you used it like regular glue and pressed tabs together while wet it's a permanent bond.<br><br>Also: excess glue and residue can be erased off the card with a regular eraser.
If you use the wood glue and let it dry, will it still warp if you put another coat on?
What's the pudding for?
it is explained in the painting section
Awesome job. Thanks for the info. I will be able to use this on some other projects of mine. <br>One piece of advice. With all that work you have done take in one step further and make it a real helmet. Look at Helicopter helmets. They are nothing more that what you have made. Your helmets could be much more comfortable and functional with a little more work. Heli helmets are a shell with a suspension system. You could adapt that to your shell and add a chin strap and have a ventilation and a real fit. <br>If you could design the top of the helmet with the visor cover seperate you could have a functioning visor also. <br>check out this website for parts http://www.flighthelmetsltd.com/helmetparts3.html <br>Great work and keep it up. Keep learning always.
Thanks for the &quot;advice&quot;. My helmet is comfortable. The visor works just fine.
Could you use this for the whole helmet? Such as make a mold from the paper model, and fill it with this?
Making a mold is another topic and is easier said than done. It should be noted that many 405th veterans started this way first to make the master cop of the helmet. A mold was then created out of that master copy and then &quot;mass produced&quot; using casting resin.
That was kind of what I had in mind. Make one of these, make a mold from it and use it to cast the resin.
i'm not at that level of technical knowledge yet.
You could also use a stencil and paint them on.
A stencil is actually more work than making a sticker.
if you spray wd-40 on a paper towel (small small misting) and wipe it on the lens, you wont have to worry about it fogging up, the oil based liquid keeps fog from forming.
You can also use a 50/50 mix of shampoo and water. You can either wipe it on with a cloth, let it sit a second or two, then wipe it off again with a dry cloth, or put it in a little sprayer, like the kind hairspray or body spray comes in, spray it on then wipe it off (I use a scrap of flannel as my cloth because it's nice and soft and won't scratch my mask, but anything soft and lint-free would work). If you're reusing a spray bottle, rinse it well (obviously), or just buy a little travel-sized one from the drug store for a couple of bucks. <br><br>I use this for my plastic hockey mask, and it works great. You can also buy anti-fog sprays from sports stores or places that sell eye glasses. I've used that too, and it works just as well; the guy at the sports store told me about the shampoo method as a money saver, which I appreciated because the little bottle of anti-fog spray cost more than my huge bottle of shampoo. It has the added advantage of smelling better than WD-40 too.
Thanks. I will keep that in mind. I may still install a small fan. It gets hot inside the helmet.
is it necessary to use white paint<br><br>cause i want to put gears of war symbols on my helmet but can't i use black paint?<br>
You want to use what ever color paint that is NOT the same as the item you are sticking the sticker on. On the example stickers I made pictured above all the white areas are the parts that the printer did not put ink on. So the white areas actually clear. The clear part I can then spray paint red or blue or silver, or gold or white or yellow or what ever. Once painted then what I have is a color (or white) image on a BLACK background. Use black spray paint and your have a BLACK image on a BLACK background - which makes little sense to me. <br> <br>If you want a black image, then just draw your design in black (reverse from mine where I colored the background black and drew my images white) and print it out. Skip the spray paint. I dont know what color your helmet is, but if the color is black or very dark consider that a black sticker on a dark background will not show very well.

Yeah, walmart, office depot, etc. Just make sure the transperancy is made for your printer type- inkjet or laser. Looking at the images you provided above, just use an inkjet printer and forget the spray paint. just print it in color and stick the double-sided sticky on the printed side.

hey dude! If you use fiberglass resin, how long will it take for the fumes to go away? its just that I have a dog, and I don't want him becoming fatally ill. I'm in a different part of my yard fenced away, but AI know the fumes can go anywhere. Should I just keep fido inside while I fiberglass?<br><br>Thanks<br>pdub92
a couple of hours
Can you resin/glue it in several stages? This would surely stop it from warping or collapsing, so is it just to save time that people do it all in one go?
many resin in stages. it all depends on how rigid the pep is. Some pieces I resin in stages (torso), some I resin all at once (shoulders). It is also about preference and comfort level when working with resins.
Ahh okay... I meant more along the lines of doing each piece in several stages: For example, resining the visor, allowing to dry, resining the upper helmet, allowing to dry, then the mouth guard, etc.<br><br>It seems that would reduce the weight on it, and as most of it would still be dry while the other has resin on, that it would not bow under its own weight.<br><br>Best ODST helmet I've seen by the way =D
thanks. Yeah thats what I meant. For the helmet I resined all at once since the paper form was very regid already. The torso I had to resin in sections - i turned it upside down and resined the shoulder first, waited several hours then resined the rest of it. I did the torso that way because the paper was very floppy when the pep was done. but some parts of the armor are very rigid after the pep is complete and can take a lot of weight.
Here's a little info on AquaResin. It is only available online for around $60 for a 2.2 pound liquid and a 4.4 pound solid but, it's very strong. It has no odor. The only thing to mix is a non-toxic powder and a non-toxic liquid.The only issue is that you need to know is that it is water based so adding thin layers the first few times is a must. The helmet becomes waterproof once dry.
ODST is the best Helmet by far in any HALO game, I believe. Thank you. I may try this... however... I was going to make a Boba Fett helmet... ran out of cardstock when the computer tried to print out the dome first. (I wasn't actually going to use it anyway)
you might try touching up around the visor with some spray paint, maybe make it seem less out of place... By the way this guide has been the best i have seen, i might do this but if i do i will go with the MJOLNER (or however you spell it... you get the idea... (I also think i might try the halo 1 version cause i like the more blocky rigid look...
Thanks for the info on epoxy resin. Can I ask your opinion on something I have found: <br>fiberglas is dangerous and troublesome to work with. The strips I cut tended to fray and unweave when I applied them, and the never seemed to lay flat enough, so I had to sand them after they hardened. The sanding led to toxic glass fibers floating in the air - BAD all around! <br> <br>So I think I found a solution: Denim. While not as strong and light as fiberglas, it's close. It wicks the resins up just as well, ans no tiny glass fibers to worry about. And it's available in any fabric supply store. <br> <br>What is your opinion?
I agree about the fiberglass &quot;dust&quot; being a health hazard. This is why I strongly recommend a respirator. Sanding Bondo and cured resin is also just as dangerous. <br> <br>Demin sounds like a great idea. People have also mentioned burlap, canvas, and hemp fibers. Please let us know how it turns out. <br> <br>
If you don't mind me asking what is the cocktail for mixing the rondo? I'm trying to make some master molds from pepakura and then vacc-form it because I want to make more than one armor . This seems the simplest way to make molds.
I mix 50/50. But it really depends on what I am trying to do. If I am trying to make a smooth, level surface, then I mix 60% resin 40% bondo. If I am trying to build up an area but need my bondo thinner than peanut butter I do 90% bondo. good luck.
By far one of the best instructables on Halo Costumes yet.
Thank you. I should have the torso complete in a few weeks and the arms done a few weeks after that. I have a few &quot;extra features&quot; I am adding to the armor too.
