Air is free! So why would you spend money buying it in an aerosol, while you can simply make your own DIY refillable compressed air duster!

► YOU WILL NEED
- Empty aerosol can
- A bicycle tire valve (I'm using a valve type "Woods/Dunlop")
- Drill
- Filler metal
- Flux
- Source of heat (I'm using here a Chef torch)
- Hot water for final quenching/cleaning

► DISCLAIMER
Always make sure you operate in a safe and secure manner.
For this project this means, make sure to pressurize the container to a level that is safe and compatible with the max supported strength of the metal joint and of the used container. Failure to do not so may results in serious injuries.
