Compressors

The 56-pound Craftsman "pancake" compressor, so called because of its flattened air tank, powers intermittent-draw tools, such as nail guns. It's 6-gallon tank offers enough air volume to feed a 1-quart spray gun for applying thin finishes such as oil-based varnishes, urethanes, or lacquers.

Compressor (includes brad nailer): 3.7 cfm at 40 psi; 2.6 cfm at 90 psi; 2-gallon tank; 82 decibels; approximately $220, Sears
