    Good surface quality can be achieved on both cants and lumber produced on chipping headrigs and on edgers, but meticulous maintenance of feedworks, setworks, knife sharpness, alignment, and security in the cutterhead is required. Straight logs with small knots yield cants with smoother surfaces than crooked, butt-flared, or knotty logs. Surface quality is also inversely proportional to pulp chip length in that feed speeds yielding short chips provide smoothest surfaces.
