Airbrush to attach directly to a spray paint can

[NortonDommi]

Hi,
Just a thought about using an airbrush away from line power and a compressor. For my daughters use I obtained,(free), some old gas calibration gas bottles from a laboratory. These are very well made but are disposable as the gasses are a specialty use, they are 1/2 a D-size. A couple were used as extra storage and as a base under her small compressor. Another had the valve removed and a ball valve and a T-piece fitted. One side of T has a standard female air fitting and the other a regulator.
To use, a male - male airline fitting is plugged onto the female fitting and bottle charged to 175 p.s.i. which is what my big compressor puts out,( Could be charged at Garage as well),then taken to site.
Airbrushes consume very little air at about 40 p.s.i. max so a charge lasts a very long time. Disposable cans are a waste of money.
Maybe a fitting could be made for old handy-gas torch bottles as well?
