I’m so pleased. I’ve got two air compressors. One of them is one of those little ones with a small tank that is good for a nail gun but any air tool that runs continuously like a grinder or air sander it can’t handle.
I’ve had a used 5hp air compressor in the garage for a long time. I’ve never used it. It works great but was miserably out of adjustment so it wouldn’t turn off by itself. Pressure would build up and the bus fuses would blow in my shutoff box after awhile.
Well, a couple of days ago I decided to get on it. I ran a 220 wire and plug to it. I set it up with a shutoff valve and let it charge and discharge air while I kept trying different settings in the switch. I finally got it to start at 80lbs and turn off at about 122lbs. This range is just right for most air tools.
Today, I silver braised some copper pipe with quick disconnects in the garage, outside the garage (driveway) and upstairs in my shop. I ran a connection overhead right over my bench and with a 20ft springy coiled hose hanging over my bench on the ceiling. I made a hook for my finish nailer.
Air is very handy. I’m also a welder and use a grinder a lot. An air grinder, cutoff too, and chipper make things so much easier, and even though not any better than electric, I’ve got an air drill. Now I can look into a few other tools like sanders. Also, being able to blow the dust off everything is a nice little bonus with a setup like this. I was fortunate to get this compressor. I felt bad that it was going to waste. Satisfying.
