Air compressor I\'ve been building in my spare time Not the most economical way to go about getting an air compressor but it has been a fun project just the same and I get a hell of a big aircompressor out of the deal and didn't have to pay for it all up front. I got the pump from a guy that said it was shot for 25 buck. Turned out it needed two new valves which put the pump expense up around 85 bucks. Made the cage for the tanks myself and don't know how much is there in steel but I did that before the big price hike insteel so not too bad. The coallescing filter and regulator I traded a set of factory rear springs for. Made the block for the air lines out of some aluminum tube and tigged end caps on. Gauge was a freeby and I don't want to go into how I got all the air hose couplers. All the lines are rated for 750 psi and up. The tanks I got for ten bucks. They were being dumped because of the valve change over on propane tanks. The tanks are rated for 250 psi so should be good to go. Need a motor and pressure on/off switch and she is ready to go. Even got a little bling bowtie on there. Was a drop out from a custom grill I made a while back.
