Finally, a quiet, powerful air compressor. Here's my newest addition to the aircraft factory tool crib. I found it on craigslist late Wednesday night. It was in San Antonio and very close to my Dad so I asked him to go by and look at it Thursday. It was owned by an older gentleman who appeared to have only used it a couple of times. The oil is still a golden color. I gladly paid $160 (sells new for around $500-$600 plus tax and shipping) for a belt driven, oil fed, cast iron twin cylinder, 5.5cfm @90psi, 115v, 20 gallon air compressor. That's about the biggest you can get and still run off household current. Any bigger and you'll need 220v. Now, I need some wings to drill and rivet to really put the compressor to the test.
