Converting a Propane Cylinder

Ok so here is the cylinder I have got. Its rated to 30 bar, or at least it says 30 bar on the side. How to I convert this to use as an air tank? I would like to keep the threads on the top as they fit my gun I am making. http://i1238.photobucket.com/albums/ff481/nathanhd123/5557f305.jpg http://i1238...

It would be attached to a 3/4" female tee. What kind of pressure can the soda stream bottles hold?

Is a fire extinguisher the best option for an air tank on the gun or is there another cheap option that can take a decent pressure?

With this setup what fitting would you use to attach the barrel to the rest of the gun. Also with the fire extinguisher do they just screw straight on if you remove the normal valve and use a connector?

Definitaly having it air tight helps. However I dont think ist the end of the worl if it leaks a bit.

Thanks, I did try google but after researching I didn't realise it was a straight conversion like that.
