Step 2: Mark Out and Cut Sheet Metal

First you need to figure out how wide your torso is. For the armor in the first picture we cut our pieces 18 inches long x 8 inches wide for the two top pieces and 18x4 inches for the lower eight. You will also need another two 18x4 pieces for the shoulder straps. It is important to not make the pieces too wide and to mark them all out on the sheet before you cut in order to make sure you have enough sheet metal. I would probably not go over 20 inches wide for most anyone. It is easy to cut once you have the pieces marked out. We used a square to mark everything, but a ruler will work just as well if your careful to keep things square. Use the kitchen shears to cut out all your pieces at once.
<p>Nice dude. I've got some old road signs I'm gonna do this with for homecoming next week.<br><br>Kitchen shears... Ever hear of tin snips? </p>
Hey, I'm loving this instructable and I'm looking to make it my first project from this site. =] <br><br>I have a couple of questions, though. What sorts of places might I go looking for the tin sheet, if not Home Depot? I went to the one closest to me, and they told me they have little sheet metal selection in any of their locations. I'm having trouble finding places online at the moment but I'm still looking. <br><br>As well, the &quot;tin&quot; also being galvanized steel? I didn't know this, and none of the sales associates in Home Depot, Rona nor Canadian Tire told me that they were the same thing when I asked for tin compared to galvanized. If this is the case, I may actually know where to look [if I can find the 30 gauge]. Can I just look for 30g galvanized steel [to make life easier asking people]?
<p>Just get any thin steel metal. Doesn't particularly matter what it is as long as it's steel.</p>
Hmmm....I wonder if this could stop Steel Arrowheads from a 10-pound fiberglass bow.....
Just wondering how flexible the arm our is
Okay, But can it defend against a bite from a dog or human? That is, if the human couldn't feel pain, and would just continuously chew.<br/><br/>Call me messed up, call me a geek, but seeing as this is in your spirit I guess I can say that i want to make full arm armour (I already have chainmail gloves)<br/>because in every zombie movie, someone sticks their arm in a hole and they get bitten, Not me, I'm sure I'll save some people's lives this way =D<br/>Hehehe, Kinda JK,<br/>
i made a breastplate from solid aluminium sheet metal. i used a ball pien hammer to make abs and breast depressions in the armor. the doming dramatically increases the armor's strength. i took it to school one day and let people unleash on me with punches, kicks, chairs, drumsticks, etc. the only thing that almost hurt was a kick from a strong junior, but it stopped it and it make a noticable dent. all i had to do was just hammer out teh dents and i reinforced the main area of the breastplate with 2 more sheets. took it to school again a few days later, not even the kick would hurt (though i stumbled a few steps back) and it didnt even dent it. i fired an arrow from the 10 pounder and it didnt pierce. tried stabbing with a knife, didnt pierce, shot it with an air rifle, didnt pierce and a small dent. the only thing that would pass through it would be a pickaxe or a bullet
what was the thickness of the aluminium? That doesn't sound like aluminium.
umm maybe 1 millimeter sheet. one layer of it is pretty weak, but 3 layers is pretty decent. the arrow will penetrate anywhere where all 3 layers are touching, but the ab and breast areas it wont. it's pretty solid because of the doming.
A 10 pound bow? TEN? It better...
well the fact that this is very thin metal it probably wouldnt. I shot from a bow with a sharp arrowhead can peice 1/2 in. cardboard, pierce sheet aluminium, and with a large arrowhead pirce through 3/8 plywood.
Yeah, but, a 10-pound bow? I've had toys with suc-cup arrows stronger than that. And it isn't a very realistic test, since any bow reasonably expected to kill anything larger than a dog would be, like, at least 50. But I like how your breastplate sounds (if only I had some aluminum).<br/><br/>Coincidentally, you mentioned being hit with drumsticks. I feel obligated to tell everyone that *PERCUSSION OWNS* and to ask whether or not you yourself are a member of our elite....percusserhood.<br/>
&nbsp;drummers rock best in the band
Apparently you've never seen an accordion. <br /> Accordionists trump all. : 3<br />
you wish<br /> i play drums at school and in a rock band
BASS IS BETTER!!!!!!!!!!!!!!!!!!!! And it has alliteration!
This is awesome!
Romans called this type of armor <em>lorica segmentata</em>. Great job!
Well, I went ahead and made this 'able. What I ended up using was a piece of sheet metal [of a gauge and type unknown to me, but harder and less malleable than the suggested metal] and a small piece of a softer tin to make the shoulders with, for material needs. I went with 20&quot; long plates and that was perhaps a bit much, but all in all okay. I completed the armour over a 5-day stretch with help when it came to drilling. The tunic and skirt of the costume were made for me by my sister, the bracers I made really simply, and the legwarmers came from the dollar store. <br><br>I would definitely try this again and have likely an easier time with it provided I got the right materials.
I like it. I think we got our &quot;tin&quot; from the air duct area of the Home Depot where they have metal parts used in heating and cooling ducts. <br><br>To answer your question my understanding is that &quot;tin&quot; is any thin galvanized steel. The confusion comes from the elemental &quot;tin&quot; (Sn) which is actually called &quot;pewter&quot; and really isn't suitable for this project because it is too soft and doesn't come in large sheets. It is also pretty expensive and lower quality pewter generally contains lead. Looks like you found some heavier gauge galvanized steel, and think your costume really turned out well. Thanks for your comments and sorry for the slow reply. :)
Also, the cape was made hastily from leftover material used for the tunic with 2 grommets, some leather cord, paper clips [lol] and a decorative silver-looking cross.
Pretty good stuff, I took the liberty of adding shoulderbads and the red robes. but thanks for a great 'Ible and a super simple project!
Nice. I like the shoulder pads. And the cape of course.
nice job
&nbsp;how do i bendit just press it over my chest?
good question, I was wondering the same thing<br>Although I figure you're probably gonna be able to bend it with your hands
i used abucket it is thinner than my body but the metal popped out a little
sounds like a good idea thx
i made it a little thicker and it's the armor that i use when my freinds and i go bike jousting
I would like to reiterate that this design is for COSTUME USE ONLY. IT IS NOT DESIGNED TO BE USED AS ARMOR IN ANY CIRCUMSTANCE!
&nbsp;arent the edges sharp &nbsp;put hot glue on all the edges to stopit
Make pauldrons Or I'll go shoot up the mcdonalds about a mile from here
no duh
made of steel that is about 3 layers thick... (i know that wcould not deflect much but it can defect cheap cardboard and nerf spears lol
&nbsp;this thing is a awsome piece of a costume
The real Roman shield (I have no doubt that someone knows the Latin word, and will let us know too) was a laminated wood with an overlay of metal.
I believe it is 'scutum'.
it is <br />
What's the best thing to use to cut 1mm or slightly thicker steel.
Personally, I would use a jigsaw with a metal-cutting blade mounted on it. Use cutting fluid to keep your jigsaw blade sharp, and as always, USE EYE AND EAR PROTECTION. Drill ~1/4" holes wherever the outline takes any sort of corner or tight curve, as trying to simply turn the saw through these areas may snap your blade.
Could you recomend a good jigsaw brand or model. I'm sorta short of cash right now and i don't want to waste my money on a cheap piece of junk or an exspensive piece of worse junk.
If you can afford a Craftsman jigsaw, I would go with that one. My jigsaw is a Craftsman, and it is still kicking at about 20 years old.
<strong>ive cut and made armor out of 2mm thick stainless steel and it is heavy but cool</strong>
20 years? Wow. Thank you.
thank you
Far out.... Very Sexy.... You can now start your own interblock / neighbourhood arms race. Make some enemies... get them to develop spears, then you make thicker armor, then they develop cross bows, they you develop long bows, then they make gun powder and firing tubes, then you make thick armor plate and better guns, then they make armor piercing shells....... Now if you play your cards right.... and pick the brightest kids for your team, you can develop the ultimate weapon - gravity bombs.. that explode an expanding gravity wave that collapses inward to generate the core of a black hole..... Now lets see the other kids top that..... Yes... clever you are.
<p>what the @#%&amp; is wrong with you man?</p>
3KRPM M134 Nuff said.
How thick is this? Is it as strong as a pop can? I need armor that is "Bite-proof" Yet is also strong enough to be made into a melee weapon (Put it on my arm and bash people in the head with it) Or is it weak enought that it can be cut with scissors? Or do i need tin snips?
