A couple of years ago I thought I needed an air compressor but wasn't quite sure why. I bought a paint sprayer that I didn't use. I bought an air nailer and an impact wrench I occasionally use. The most common use of the air compressor is to fill up tires. It seems like all of the tires have a slow leak. In a way I am glad to see all that I have more use for the compressor than I originally thought. The bad news is that by thinking about the air compressor reminds me how much I underestimated the work involved in keeping a farm running.
