Thanks for the recommendations. I checked Harbor Freight and some other places. What I wound up doing was taking two old compressors to make one that works. About 30 years ago I bought a complete air compressor (pump, motor, and tank) at a yard sale. It was old then. The motor is a Dayton and the brand name was something like Speedco or something along that line. The pulley on the pump worked loose and ruined the end of the shaft. A couple of years ago a retired farmer in the area was doing a bit of  cleaning up around his place and he gave me another one that had the John Deere logo on it. Not sure who actually made it. Its motor was wired for 220 and I don't have a 220 plug available so I swapped the motors and fired it up. It worked but sounded terrible so I took it apart and found that the connecting rod on one of the pistons was broken. I removed that piston and used it as a "one cylinder" until it quit working recently. So I disassembled both and used the good parts from each to make one that works. Mounted it on the "John Deere" tank with the Dayton motor. So far, so good. If I counted my time anything I didn't save any money but the only thing I had to buy was a quart of motor oil. I don't need very much of an air compressor since I only use it to air up car, lawnmower, and bicycle tires. Occasionally a small sand blasting job for paint prep. Here's what I wound up with. Still had to install the guards.
