Of course, the oomph for pneumatic tools has to come from an air compressor.
Many woodworkers now use brad and finish nailers to greatly speed assembly of projects.
To see how the compressors stack up in this popular operation, we set their regulators at 90 psi and drove 1-inch brad nails into 2x4 material with a single brad nailer, holding the trigger and firing nails until the compressor cut in. We did this three times with each machine and averaged the results. Again, we timed each unit three times and took the average. Finally, we put each compressor to the test spraying water-based polyurethane. First, we determined the pressure that best atomized the finish, then set each compressor to this specification.
