Pie-cut Pie cut Method Used when a defect is deep and pie shaped, contained within a sector of a circle The deduction has the same relationship to total scale as the sector does to the circle Deduction estimates of 1/8, 1/4, 1/3, 1/2, or 2/3 are used Defects that this method applies well to include catfaces, catfaces, fire scars, grubworm holes, and rotton knots
Length Deduction Method Used when defects result in lumber shorter than log length It should be used when the deduction for squared defect exceeds the scale of the log length Such defects may include sweep, fire scar, knot clusters, large burls, breaks, crotches, massed pitch, and rot
