Years ago a friend of mine had one of the neatest set ups for airbrushing in an apartment I've seen. He had found an article in a British model mag on setting up a foot operated airpump and an old inner tube as a source of compressed air (the pump is designed to be carried in the trunk of your car and used if you had a low tire and no filling station was available -think you can still find them in an auto supply store). You filled the tube with the pump, disconnected it and connected your air pump (usually about 40 to 45 lbs of pressure initally available.
Bill went a step further. He had a machinist friend built him a T fitting that threaded onto the valve stem. The side of the T fitting that the compressor attached to had a valve stem installed and line to his regulator hooked to the opposite side. When he wanted to airbrush, he would steal the spare tire from his wifes car (which was good for giggles occasionally), pull the valve core, install his fittings and hoses, lean the tire against the wall under his bench, pump up 60 psi (took about 5 minutes)and start airbrushing. When the tire got low enough, he would pump pressure up and continue (couple of minutes). When he was done, he would pull everything he had installed, reinstalled the valve core (only forgot once that I know of), pumped the tire up to 32 psi and put it back in the car. Extremely quiet. I did once ask him why he didn't go to the junk yard and just buy a tire and rim, to which he replied, "why heck do I want to spend 5 bucks when I have a perfectly good tire out there doing nothing?"
