You can never just have one

.
I current have 3.
1) Husky 30gal 2hp Cast Iron, picked it up for $50 from a painter friend. Nice little unit.
Needed a oil change and some cleanup.
2) Devbliss Pro Air 4000. Oil FREE 60gal 5hp peak. This was free from a friends father shop.
Needed a pressure switch, the armature cleaned up, and some new wiring. Currently serving duty at my fathers shop. Provides dry, oil free air for his wood working and car hobby.
3) Champion R15 5hp 80gal
Purchased this from one of my favorite junk places. I never thought I would find a air compressor there. It was sitting in the yard, looking awful neglected. Thankfully they covered it before it rained. When I asked the yard manager if I could buy just the pump and compressor, he said hell no. Well, I said fine, how much for it. I believe he was joking me when he said take the whole thing for $35. HA! I said sure. Some of the other staff weren't to happy to see me driving away with this thing loaded in the bed... He even tossed 300ft of rubber air hose

Its a Champion R15 pump with a GE 5hp 220v motor. The tank is a 1940's and first on my list of things to replace. I will find a better picture and a before picture when I have a chance. Should be good for 130psi at 18.3CFM. Cant wait. We tore apart the entire thing, cleaned it up, painted it, checked out the pump, new oil, new air filter, rebuilt the pressure switch, and reassembled the entire thing.
Total in to the project is around $240. Not bad for a compressor selling still for $1500+.
*Edit found the picture! Its quite the change...
*Edit 2, better photos. And we fired it up tonight! Runs like a champ!
