I wanted to see if papercrafting was possible using aluminium cans (ie. Coke cans), I did a bit of a google around and there doesn't seem to be a lot of information on the subject, so I figured I'd do some research and try a few techniques out to see what I could come up with.  I've split this into sections to make it a little easier to read.
If you've never made anything out of papercraft before, I suggest you look elsewhere Papercraft Museum and make something out of paper, it takes a significant amount of more effort (and time) to work with aluminium.

Step 1: Flattening Aluminium Cans

First up, I used a knife to cut the top and bottom off the can (you can use scissors, but you'll need to use a knife to get a start to it) and then using scissors to chop the cans into a piece I can flatten. After you've cut them into sheets like that, neaten the edges by using a pair of scissors to cut them straight and make sure there's no little sharp bits.
The method for flattening the cans that I've found works best is to use a sandwich maker (an old one, don't ruin your good sandwich maker!!). Before turning it on, lay down a piece of baking paper on the bottom, put about 4 cans in, then add another layer of baking paper on the top (this should help prevent at least a little bit of damage to the sandwich maker).
Hold the cans down flat as you close the lid, once you've done that, turn the sandwich maker on.
I haven't fully experimented with getting the best efficiency here, but I left it on for 10 minutes with 4 cans in there, then turned it off and let it cool before I opened it.
Taadaa! Flat cans!
Other methods I have tried are:
* Ironing (Does nothing)
* Ironing and bending at the same time. This method works, but you end up with your piece looking a little bit bent as it's hard to get it as flat as you would in a sandwich maker.
* Clamping it between 2 pieces of wood. This does absolutely nothing, if you leave it for a day or a week, they bend right back to their natural shape.
It seems like heat is very important in getting these things to stay flat.
<p>You need heat to flatten the sheets because they're covered with a plastic film, that's why they will always get back to their round shape unless you heat them or grind them thoroughly (the inner side which is in contact with the drink).</p><p>The good thing with the heating method is your sheets will tend to come back to their flat form if bent moderately (i.e. as long as the plastic film is stronger than the aluminum lack of elasticity), while they will remain bent with grinding (no counterforce).</p><p>If you want to give your sheets a specific shape, e.g. to sheet a wing or a hull, pin them (liquid side outwards) and use a (cooking) blowtorch to set them to shape. When unpinning, they will keep their form.</p><p>Epoxy (or most plastic glues) will work on the liquid side if you sand it lightly first (100 grit or lower), don't go to the metal. Nothing will work on the outside (the layer of plastic is too thin).</p>
Oh wow, that's awesome :D
For those of you thinking to try Epoxy glue, this is what happened: <br> <br>1. Mixed the Epoxy resin stuff with the hardener <br>2. Stuck the pieces together and held them for 5 minutes. <br>3. Let go of the pieces. <br>4. Observed as the aluminium flexed itself back to how it was before being glued (apart!) <br>5. Stuck it back together and used a weight to hold them together <br>6. Let it sit overnight <br>7. Tested the glue strength, seems to be holding well... <br>8. Flexed the metal <br>9. Glue breaks off, metal falls away. Sadness ensues. <br> <br>Basically: Epoxy works if your metal isn't going to bend at all.

You can also reach me at norma.eslick@gmail.com<br><br>If anyone else if reading this and wants to make a little extra money by selling me a sandwich maker with flat surfaces (no ridges to cut thru bread) please let me know by contacting me at the above email address. I would pay the cost of the sandwich maker, shipping, and $20 above that for helping me out with this. <br><br>Thanks,<br>Norma
Lucky you, my sandwich maker has a pattern.....
Over the years we've gained 4 sandwich makers, I was glad to put one of the old ones to use :P
Hi duk242, I hope I'm not being a pain in the ass but I'm leaving this message b/c the email I rec'd from instrtuctables (to leave messages here) made me think I'd put them in the wrong place and perhaps you hadn't rec'd either of the 2 messages I'd already sent to you.<br><br>Long story short: I'd like to purchase one of the sandwich makers you mention in the comment shown above. I expect you to make some money for your time and effort as well so let me know how much you want and of course add in the cost of shipping.<br><br>Hope you get this message. <br>Norma<br>
<p>I'm trying to find a flat-surfaced sandwich maker (without a ridged pattern). I would be happy to take one off your hands if you'll tell me how much you want for it. I'd pick up the shipping cost as well. Thanks, Norma</p>
<p>Forgot to mention: I live in Texas, USA, so let me know if you don't want US dollars and I'll find out where to get Australian currency. Pounds?</p>
<p>Hey Norma, shipping from Australia to the US would be insane cost wise (that and our appliances run on 240volts instead of 110).</p><p>However, I think I found the right one for you on Amazon, check it out here: </p><p><a href="http://www.amazon.com/GAU-80102-Electric-Panini-Sandwich-Nonstick/dp/B0018E6HGI/" rel="nofollow">http://www.amazon.com/GAU-80102-Electric-Panini-Sa...</a></p><p>If that link doesn't work, just do a search on Amazon for Sandwich Maker and there's quite a few flat ones on there :)</p><p>Thanks,</p><p>Ducky</p>

Thanks for sharing your findings! I'm working with aluminum right now too and found this information very valuable. <br>For another adhesive option, try Glue Dots...you can find them in the scrapbooking section of a craft store. They're super sticky for an instant bond. You can also find Mini Glue Dots for smaller work. <br>For others on this thread...I finally found a flat sandwich maker - it's a Cuisinart panini press/griddle with removable plates...the plates you remove have grooves, but once you remove them, you're left with two flat surfaces :)
ah. found it! <br>
what is the template called?
You could try soldering the aluminium pieces together. then you only have to wait 10 sec for it to cool.
I considered trying that.. then my 3D Printer arrived so I put it on the backburner for a while... I might give it a shot some time though (I'll post here if I do)
If by solder you're thinking of using a regular soldering iron and solder used with electonic circuits, make sure you buy solder for Aluminum. Regular solder won't work... it'll slide right off. (Nice work by the way) :)
One thing to try is using sandpaper to roughen up the parts you want to glue together.
I sort of tried that, I used my scoring tool thing to scratch up the surface a bit, it helped a little bit but not as much as I had hoped...
Aluminum is difficult to work with. You'd think it was the easiest stuff on the planet to work with, since it's used in so many ways, but it isn't. It actually is really hard to glue or paint, because it forms a film fairly fast on the surface that must be removed right before you glue or paint it. Aside from that, cans have a plastic coating which glue doesn't stick to. Scratching it with pointy tip isn't going to do anything, considering the &quot;scratched&quot; surface is such a small fraction. You really need to physically remove the impurities with fine sandpaper or chemically with harsh cleansers. <br> <br>Anyway, if you prepare it properly, good epoxy glues will hold well. Of course, you'd want to form the pieces first, so they don't want to pop apart, especially if the glue surface is going to be small, but that can be overcome with reinforcements possibly (depending on design I guess). <br> <br>End result of your instructable came out great. I'm going to have to give it a try.
this is awesome. great instructable.
Just a little tip, if you sand the pieces you were to glue together and clean them with acetone than water, it might stick better.
the result is really cool, thank you for sharing all the gluing information you learned as well
