Hard Maple Bark Pockets

Question: When grading hard maple in central pa we often see ingrown bark on the opening face of the board but on the back it is clear. It is difficult to determine if the bark will surface out to standard surface thickness, should we stay fast to grading by the side with the least amount of units determines the the grade? Answer: One thing to note is that on page 4, paragraph 4 of the rules book it states: “Lumber shall be inspected and measured as the inspector... Read More

Pin Knots in Red and White Oak

Should sound pin knots in red or white oak be cut over?  This question is a very interesting question and has been a question for years from many different areas of the country. The short answer is no, you are not allowed to cut over pin knots in a clear face cutting in RO or WO unless there has been an exception written on the purchase order.

If only one side of an FAS red oak board exceeds the mineral limitation than it would be reduced to a F1F.  Read More

Cherry 1/8" Knot Clusters

Question: When grading cherry, I am hesitant to cut over the "Cat's Paw" clusters of pin knots for clear-face cuttings.  Each individual pin knot does not exceed 1/8 inch, but clustered together so tightly, the appearance is that of a knot larger than 1/8 inch.  Further, many of these boards have numerous clusters, giving the entire board a "dirty" look.  Can I cut over these clusters? Answer: On page 25 of the 2011 rules book it states under the species of cherry that... Read More

F1F Pith Rule

Does the FAS pith rule apply to F1F lumber?   The FAS pith limitation is: “56. No piece shall be admitted which contains pith, boxed or showing , exceeding in the aggregate in inches in length the surface measure in feet.”  I interpret this to say that if I see pith on the FAS side at all than I would have to say that it is boxed for a portion of its length and that is what I would use to determine if it exceeds the limitation for the FAS side of the board.  If...
