Re: At Home air compressor (cheap)
About 40 years ago I built one with the York-type compressor from a deep freeze we got right after the war. By the early '60s the box was rusting out so I got the compressor. Put a pressure switch and relief valve on it, and a pressure head tank from an old steam heating system. The pressure switch was set for 125 PSI. It ran for another 35 years, and the compressor was still working but the tank finally rusted out. It only had a 1/4 HP motor on it, and was pretty slow to fill the tank, but the tank was about 35 gallons, and I always left it plugged in, so I always had plenty of air for blowing stuff off and inflating tires. Any significant air tool ran the tank down, and then it took half an hour to get pressure back, but it was a great machine for many years, and only cost a few bucks for the switch and relief valve.
