Step 10: Pump it Up!
Unscrew the tire valve cap, and hook it up to your pump.
Pump it up until the gauge reads about 35-40 PSI. You probably shouldn't pressurize it more than 50 PSI.
Check for leaks. If there are any, it might work if you seal it up with more PL Premium (I don't know for sure if this will help) and let it dry.
Detach the air-osol can. (Yay, you can finally call it that!)
Spray to your heart's content (or until the air runs out)!!

I got 18 AXE cans saved for inventions. I would prefer using the original spray valve (opens when pressed down), just making an adapter for it . It would be safer than having an AXE can go BOOM in your hand or face.
I wanted pressure calculations, so this is what I came up with:
The can comes with 150ml deodorant.
The can's volume is 200ml
That means that 50 ml (actually a little more) is compressed propane in a new bottle.
When the can is empty, the propane is at atmospheric pressure (15 PSI), and occupies 200 ml.
That means when the propane is compressed from 200ml to 50ml it reduces to 1/4 it's volume, thus (if the temperature is the same) its at 4 times it's original pressure
That is 15 PSI * 4 = 60 PSI Very Safe Pressure FOR AN UNMODIFIED CAN
These calculations are very rough, because the can actually releases a lot of propane while spraying, and an empty bottle might still have gas left inside.
I suppose that they fill at 75 PSI.
Another test method would be:
Dig a hole about 75 cm down, get a long extension for your compressor, and put the can in the hole. Get pressure into the can. Keep an eye on the PSI meter and stay away from the hole. When the can goes BOOM check your PSI meter and subtract 10-15 PSI to get a safe pressure level due to heat expansion.
Nice 'ible BTW
I've pumped the can up to 60 PSI with no problems... i guess the bond is good. But those safety rec's are helpful.
If you do manage to make an axe valve adapter so you don't have to hack out the can, please post an ible! I'm sure I and others would love it. On a side note, though, if you're going to do that much to an AXE can, you might as well somehow attach it to a soda bottle or other bigger (whip cream or air-duster size, or aerosol suntan lotion) container. It would just be more useful that way, and you could fill it with paint, alcohol (flamethrower, anyone?), or chemicals to kill pests and weeds, etc.
