FILENAMES: compressor.jpg DESCRIPTION: This is a picture of a cobbled together air compressor. Posted by John . The following description was provided: ================================================================= This is a photo of an air compressor that I built from salvaged parts. I know the photo's terrible, but it was a test shot from an "I-Zone" toy camera. [ramble] A yard sale provided the motor, the pump came from a scrap metal bin, the pressure switch from eBay, and the tank from the same scrap bin. The tank and motor were sanded down and painted flat olive drab from about 1000 spray cans. That reminded me that a paint gun is one of the best used for a compressor. The pump only needed the crankcase gaskets replaced. It's had so little use that the honing marks in the cylinder are nice and sharp--I have no clue why someone would toss a cast iron compressor. The only other major parts were all the brass tubing and fittings. Sears used some sort of all-in-one manifold (which was missing) for air handling. I had to design my own system for getting the air from the pump, through the check valve, out of the tank, and also to the unloader. I'd have to say that it looks pretty good for generic pipe fittings. It's a 1/2HP, 1750 RPM motor that turns the pump at around 460 RPM. I'll change it to a 1HP, 3540 RPM motor someday, but I'll need to paint it to match first. The tank is a 20 gallon model that was originally a Sears/CH from the '70s. For you safety freaks, yes, I did water test the tank before using it.. The switch is set to go off at 108 pounds and on at about 81. I also have an emergency valve that blows at 150. I'm very happy with the end result, especially the fact that it's so much quieter and more durable than most equal modern compressors. [/ramble] You can wake up now.
