I returned to the job site with my new goodies and soon discovered that I had indeed made the right choice. The compressor started right up and was soon pressurized and ready to go. I hooked up the hose and gun, filled the reservoir with stain, and started systematically applying it to the siding. The portable air compressor was on wheels, and easy to maneuver. I could see the dry wood soaking up the stain and I was happy I'd opted for this method of application. I dreaded the idea of having to brush stain on for hours on end. Once I had the first coat on I let it set for a couple hours while I took a break, then went back out and applied a second coat. This probably would have been sufficient, but I had read that the very best thing to do when applying stain with a sprayer is to go back and brush over the job. Doing this really drove the stain into the wood and allowed it to fill every little pore.
Like most other machines and even robots, this kind of machine has its types that serve a particular kind of industry, or even hobby. The evolutions did not only make the air compressor pump dependable equipment it has become more reliable too.
Years later, I built a smaller woodworking shop in my home which only required one air sander running at a time. For that shop, I purchased an air compressor half the size and isolated it in a soundproof room in one section of the shop. I ran galvanized pipe under the shop floor to three regulators at three different connection locations. The machine I purchased for that shop as a 5 HP Ingersoll Rand model with an 80 gallon tank. At the 80 PSI required by my Dynabrade sander, the compressor would produce enough air from morning to night. I must say that that compressor was very well built. All I had to do was keep an eye on the oil level in the sight glass. At night, I would turn off the master air valve on the side of the air compressor, leaving the electricity on, to silence the compressor until the next work day.
