FIRST OF ALL: i know there are other instructables related to this...

they both involve placing a container inside the can, so what do i offer you guys with this instructable?
I offer you an idea, thats about it, this is the way i have been doing these kind of containers for a while now, i think the design is pretty simple and i hope you guys like it, i just thought another instructable on the subject would do no harm
but anyways lets get to it...
I WELCOME ANY SUGGESTIONS PLEASE COMMENT IF YOU HAVE ANY
Step 1: Gather Your Tools and Supplies
1 Empty Spraycan (press on the nozzle, you shouldnt be able to hear any air escaping the nozzle)
1 Empty Soda can
1 xacto knife OR any knife you dont mind abusing
1 ruler (the thickness of the ruler might be important, ill tell ya later)
some clear tape
some paper glue
some contact cement
Step 2: Getting Started
IF you want to use the same label either cut the label off as one piece of carefully cut it at the same level in wich you made the line
Step 3: CUT... Put Some Elbow Grease on It...but Not Too Much
Feeling Lazy??, the text in bold letters is what you have to do!, the other text is what you have to do to stay out of trouble in this step
i set up my workbench as shown in the pictures, it helped a lot in keeping the can in place; find something similar and it will be easier to work with
grab that useless knife...
this is the knife i use to cut through plastics, i bet we all have at some point heated a blade for this purpose.... i just gave it a few strokes with a coarse sharpening stone and i got a coarse cutting edge on it wich is what we need (a serrated blade might also work id look for one with small teeth)
I AM NOT RESPONSIBLE FOR ANY INJURIES OR DAMAGE TO PROPERTY OF ANY KIND
FOLLOW THESE STEPS AT YOUR OWN RISK AND USE COMMON SENSE IF YOU HAVE ANY
start trying to cut through the line but do not put so much pressure on it cuz you will dent the can (once you have no pressure inside anyway)
IMPORTANT! FIRST concentrate on one spot , dont move your blade along the line just yet, slowly but firmly notice how the blade starts to take metal away on that spot UNTIL some air starts to come out, IF you do this with much force you might make a big hole and the leak of air will be bigger and LOUDER so, do this slowly, AND AFTER YOU SEE AND HEAR A LEAK LET IT VENT OUT, keep the hole facing upwards so you dont get paint all over your project
CAUTION: this might be a flammable gas (im actually 99% sure it will be) so keep away from any ignition source
when the can is done de-pressurizing (youll notice it gets really cool while it does this XD ) keep cutting through the line, use the edges of the last spot you cut through and continue from there, its a bit easier that way, be careful not to make too may dents (we'll take care of small dents later on)
Once you are halfway through the can's perimeter the first orifice will be at the bottom (where any leftover paint might be) so you might want to place a container on the floor , in case your setup is different from mine its ok, just know youll have to do something about the paint issue
I DO NOT USE POWER TOOLS IN THIS PROJECT BECAUSE OF THE "GETTING THINGS ON FIRE" FACTOR,
THERE IS A WARNING IN THE CANS THAT SAYS "DO NOT PUNCTURE" FOR A REASON, I FOREFEIT ANY RESPONSABILITY FROM THE SPRAYCAN COMPANY AS SOON AS I IGNORED THAT WARNING AND SO DO YOU!
im sorry, im a bit paranoid when it comes to covering my "behind" from legal issues
the last part where the sheet metal was joined can be cut by rocking back and forth the pieces, IF you already weakened that spot by making a good line with your knife
Step 4: DETAIL
remember those smalll dents i told you about?
use your soda can to smooth them out as shown in the pictures , the remaining imperfections can be corrected using your fingers
Step 5: Put It Back Together
well grab your scissors and cut a strip from your aluminum can
as you can see in the picture i cut a strip along the whole perimeter of the can, and then i made a diagonal cut to open the "ring" this was an intentional step
on the second picture i show you how this works to get the exact diameter we need, press with your fingers in the direction shown by the arrows to get a good fit , then with a marker draw a line at the bottom to even out the bottom, and then cut along that line, do the same for the top part
now apply some contact cement on the inside of the can and insert the ring as you did before, (this has to be done quickly so practice first)
for an easy opening and closing of the can i recomend doing some V shaped cuts (not any deeper then 1/8" )along the whole edge and bend the spaces in betweed slightly inward
i only made one since i wont be opening this regularly, and i want those stinky cubans to stay sealed
Step 6: Testing....
Step 7: The Creative Step
use any image editing software you want, just make sure it has rulers on screen and adjust as necessary... i scanned one of my drawings and resized it
i decided to cut my image a bit short on the cap end and a bit longer on the body end so it wouldn't get too messed up when closing it, it was a mistake! not only does it get messed up but its also harder to close it and take care of the design at the same time
next time im going to cut it the exact distance on each side...
Step 8: Finishing Up
we will be using the line where the sheet metal was joined as a guide for this step
place the body part of your label in place , to make sure its aligned properly check that it can go all around the bottom edge staying inside as shown in the second picture, and also align it as best a s possible with the line i mentioned before
hold it with some tape (picture 1)
repeat process for the top part
after you have secured both parts of your label with tape, put some paper glue on the overlapping side of your design and ... um just glue it together, i dont think i need to explain much here
i understand there are other ways to do this, this is just the way i did it, as long as one person gets an idea to do something using whatever "technique" i used here even if it has not much to do with a spray can the effort was well worth it
