J. Gibson McIlvain uses a grueling, minutia-filled process to grade their lumber. Customers who internalize the following 10 foolproof steps will be able to understand the process, and even do a bit of wood grading on their own. An amateur will not assess lumber with the quick assurance of a trained professional; however, these steps, along with a basic knowledge of NHLA terms, allow anyone to relatively determine the grade of a board.
Step 1: Find the specifications for the particular species of lumber.
Step 2: Find the board’s SM (surface measure).
Step 3: The grade relies on the lowest graded face, the poor face. Find this and begin.
Step 4: Each species has specific grade rules. Follow those to decide the grade of the poorest face. Re-check the decision again the specifications for the grade.
Step 5: Measure the board for size requirements.
Step 6: Determine the amount of clear and sound cuttings available. Check against the grade requirement.
Step 7: Multiply the specific cutting yield by the SM
FAS = by 10
No. 1 = by 8
No. 2 = by 6
No. 3A = by 4
No. 3B = by 3
Step 8: Determine the amount of maximum cutting area and how many cuttings it will yield. Check the cuts for specific size requirements.
Step 9: Repeat steps 1-8 on the other side of the board. The final grade will depend on both sides.
Step 10: Review each qualification again. Include allowances for wain, pitch and imperfections. Only now can a grade be assigned.
