We have been using empty cans prepared exactly like this in RC planes to operate the landing gear for decades. I fill mine usually up to 5-6 bar. Thus far I never heard of any exploding. On the other hand, RC modelers usually know what they are doing when it comes to soldering and other technical stuff.
Long, long ago I had thought of doing the exact same project, but I decided not to, when I considered the following: 1. The propellant in a normal spray can is NOT compressed air. Used to be cfc or some other gas which becomes liquid when compressed. During manufacture, the can is filled with the liquid propellant, the liquid to be sprayed, some air space, then the whole thing is sealed up. Some of the liquid propellant becomes gas and builds up pressure. Eventually enough pressure is reached to stop further evaporation. The problem is, what is that pressure, and what is the pressure the can will take before exploding? It may not be as high as you think. So I decided it was too risky to try making. 2. To pump air in to a safe pressure (how much is that?) is good advice. However, unlike the propellant which constantly evaporates to maintain the pressure in the can as you spray, in this diy can with pressurised air, you will very rapidly reach the point where the remaining pressure is not sufficient to be of much use. That is why I decided way back then that it was not advisable to try it. Probably safer to use a Tubed tyre, with a high pressure hose leading from the valve to an air spray gun.
Without some sort of activation energy in the presence of a combustible fuel, an explosion from atmospheric air is not possible. This project is missing 2 parts of the fire triangle. So fire is not a concern here. Even when he was soldering. Unless the can wasn’t rinsed. Even then, with that drilled hole, no way enough pressure could build up (during solder).
@@johnsanchez8029 didn't mean explosion in the sense of the Fire Triangle. Was thinking of explosion due to too high pressure being pumped in. How high is too high? No one knows as commercial spray cans were never meant to be used for this purpose, so it is very unlikely that the manufacturer would specify what is the max pressure the can is able to withstand.
if you put it into a metal cabinet you can then pump it till it blows up then you'll know what that is, just an idea. But yeah you should not try any of it if you don't feel smart enough for compressed air, there have been indeed some deaths. Another thing is you will discover that it is your newly attached refill valve the first to go, way before the can explodes, and it might shoot into your face, so it is to be positioned in a safe place and not up there into your face.
Much easier to remover diffuser at the top. Place automotive valve stem over pin and add compressor air. Control pressure with line valve on compressor. Safety issue addressed.
Yep, pretty well covered BUT.. a note to: A' confirm the can is empty before drilling.. B. purge explosive gasses from can prior to soldering. C. fill cup around nozzle with water to avoid over heating the plastic valve during soldering. and all is good. PS, most spray cans have a design limit of 100psi, so use caution when filling, a rupture would make for a very bad day at ICU.
@Scio qui sum -Je sais qui je suis I have a cheap Pneumatic air hand pump that goes up to 1,500 psi. Don't listen to scio's info. Anything dealing with compressed anything has a danger.

This really works and is practical, but don't expect it to last anywhere as long a new compressed "air" can on one inflation. The "air" in new cans is actually any cheap gas that can be compressed until it's liquid in room temperature (usually butane, propane, relatively non-toxic refrigerants are said to be used as well), and air unfortunately can't be, so there is much less of it than weight. If you can only find bike tubes with plastic valves that have metal thread, they can probably also be used, as they are actually brass inside, just scrape off the plastic. Solder holds better if the can and the outside of the valve are brushed with a metal brush. A can inflated to 6 bar is enough to dust a keyboard thoroughly once, and in some other video a guy (ruclips.net/video/rR-S7-fAVTg/видео.html) inflated a spray paint can to about 15 bars, and the top dome moved out a bit around the rim, but it remained intact until it was inflated to 25 bar, and the bottom lid came off, sending the rest of the can in opposite direction at high speed. But for this you need a good big shop compressor, not the cheapest car tire compressor that also happens to be ten years old.
Good idea! Depending on the contents of the can the flame could cause an explosion, that would be exciting. A big soldering iron might be safer, you would then have something left in the can to spray!
The drill shards enter the can and then get stuck in the spray head? Might be wise to punch a hole with a super sharp nail if it doesn't deform the surface any for soldering.
This will only hold a very small amount of compressed air, because air cannot be liquified. So you would have to refill it after a few seconds of use. Thats why commercial compressed air cans are filled with lighter gas (butane gas).
I have a heap of compressor gauges and outlets so my plan is... do above with a larger vessel, valve will ensure a pressure limit. Provided I can fill with my air compressor, it has a 3 stage moisture trap... so I can finally de-dust my pc without having to disconnect and take outside.
You can also do a painting can with this . If you drill a second hole and add a filling cap, with a seal, with the same method . Rinse the can, dry it . Now, you have to fill a half of the can with liquid paint , close the cap and introduce air through the valve, using a compressor , until you reach 6 or 7 bar pressure . And just painting .
Yes , you're right, but it seems to me that can be difficult to add paint through the little hole of the valve, you don't think ?? And over time, the paint could partially clog the valve ?
Nice! next I'l have to figure out how to reload the can with color medium.... Could of course try to enter it through the same hole. But that hole afterwards is soldered so I would need to perforate ad infinutum to make this a good reusable toy.
If you oh so desperate for an expensive can of air. You can use propane can for dusting. Same stuff they use. If safety is your concern and being a cheapskate too. A tire inflated to 40-50 psi with an appropriate attachment would do nice too. I airbrush toys using car tire as an air source. A nice learning experience.
Safety Police Comment: At 0:32 video shows an awl trying to indent a hard curved surface. The action of the awl is directed at the opposing hand. Clearly an opportunity for a slip of the tool to perforate that opposing hand. Take note of shaky herky jerky action at 0:32. Never place yourself in the line of "fire" when using hand tools. Always wear your work gloves.
all this while adding a valve stem to a spray can that could pop off at any time and poke your eye out while filling it, using it, or just sitting there because soldier weakened too much from the pressure.

No to bond metal on metal you use flux and 60/40 solder. 60% tin, and 40% lead. Electronics solder uses a flux core solder. This is a different type of solder and does not create the proper bonding of metal on metal, It is used to bond a copper, brass, or gold surface to a tined PC board surface.
how to create something that can easily explode in your hand. the aerosol can is only designed for one fill-empty cycle. Each cycle stresses the can. A few cycles and that thing is going to pop. DO NOT DO THIS.
I pump bicycle tires to. 85-110 psi easily even that is more than enough for a duster. Personally I'd thread a fitting in through a hole then solder it.
i think bevore the aerosol can explode will the valve pop up from the can. The solder connection will never be stronge than the steel. I think this construction is idiot safe^^ But only a Test can 100% prove this^^ who test it^^
Just use an air nozzle with a rubber tip. It will both fit over a stem if the spray nozzle is removed and just hold it against the hole if he nozzle and stem are connected.
So this is just regular solder brazing? I didn't know it was that simple to work with aluminium. Making a few of these so you can have unlimited rechargeable air would sure be handy - even if they wont last so long. I really hate to pay for compressed air cans. It just seems like such a waste - but in some cases they are just the perfect tool. I would definitely find a can to use that can use a long straw
I'm surprised that it worked so well,my dad had a similar idea and when trying to solder a fitting to the can the plastic spray nozzle melted,his idea was for making a cheap refillable paint can though.
Probably should have mounted the valve on the bottom or side that way you can keep the plastic parts and nearby metal immersed in water to protect them. though you need to pressurize the paint and it cant be too viscous and if it dries within the nozzle its over

someone is going to lose a hand maybe a life doing this crazy stuff. that cans not made to take near the pressure that a compresser or even a bicycle pump puts out. and pouring water on a fresh solider join makes it weak. cools it to fast.
Just like everything in life, excess is bad and can lead to injuries. So yes, over-pressurizing a container can cause it or the joint to fail. This as a result can hurt you, yes. Also, good point about the fast cooling, quenching/cleaning of the flux was done here with hot water.
Areosol can has on average about 40-60PSI (2,7-4BAR), and has to be tested to 120PSI(8BAR+). On average the can is damaged at over 200PSI (almost 14 BAR). Average good quality bicycle pump is rated up to 85PSI (6 BAR). As a matter of fact, pumping air into areosol can is very inefficient- because of quick loss of pressure. Standard cans use liquid propellant, which vapouring is providing constant pressure for long period of time (in comparison to compressed air).
@@TheLabOtomy Okay!...In your case, common sense is an endangered species. Nothing in the world is more dangerous than sincere ignorance and conscientious stupidity.
Room air is not dry. The moist air is not a great idea for cleaning electronics, but for blowing general

How long does the can spray continuously,??? Please anyone help me find the answer
Dangerous. and whats the point.
BIEN EXPLICADO MASTER, EXCELENTE APORTE, GRACIAS...
someone is going to lose a hand maybe a life doing this crazy stuff. that cans not made to take near the pressure that a compresser or even a bicycle pump puts out. and pouring water on a fresh solider join makes it weak. cools it to fast.
Just like everything in life, excess is bad and can lead to injuries. So yes, over-pressurizing a container can cause it or the joint to fail. This as a result can hurt you, yes. Also, good point about the fast cooling, quenching/cleaning of the flux was done here with hot water.
Areosol can has on average about 40-60PSI (2,7-4BAR), and has to be tested to 120PSI(8BAR+). On average the can is damaged at over 200PSI (almost 14 BAR). Average good quality bicycle pump is rated up to 85PSI (6 BAR).
As a matter of fact, pumping air into areosol can is very inefficient- because of quick loss of pressure. Standard cans use liquid propellant, which vapouring is providing constant pressure for long period of time (in comparison to compressed air).
Data driven answer, I like
ice bank myself
You realize that the CO2 in canned air is 145 PSI, and bike pumps barely put out 40... right?
itu pake air cairan soldernya pake air keras ya gan??
Drilling on a round surface while holding the can in your hand? 0:36 You're not too smart, are you?
No, am not, so please explain!
@@TheLabOtomy Okay!...In your case, common sense is an endangered species. Nothing in the world is more dangerous than sincere ignorance and conscientious stupidity.
@@250rapid What do you mean?
True that was pretty stupid
Chill out. 0:32 The guy punctured it first!
