Some types of wood are sold at a specific width and “per lineal foot” of length. This is in contrast to “per board foot,” which is a volume measure, and can be used to tally lumber of random widths. Example: If a 1 in. X 4 in. X 10 ft. board is priced by the … Continue reading Lineal Foot (“LF”)
“BF” is a volume measure of lumber. It is calculated using the dimensions of the lumber in the rough. This means that it uses the measurement of a board prior to planing or the application of a straight-line rip. How to Calculate: Thickness (in inches) X Width (in inches) X Length (in feet)Then divide the … Continue reading Board Foot (“BF” or “Bd. Ft.”)
Lumber size is often referred to as 4/4 (pronounced FOUR-QUARTER), 5/4 (FIVE-QUARTER), 6/4 (SIX-QUARTER), etc. This refers to the thickness of the lumber when it is first sawn and in its rough dimensions. 4/4 lumber is sawn in the rough to a full 1 inch. The size increases in 1/4″ increments. 5/4 lumber is sawn … Continue reading Quarter Measure
This is the hardwood grade which includes the superior “furniture grade” hardwoods. This grade is typically free of defects, but some defects are allowed.
“RGH” indicates that the specified material is being sold as it came off the saw. It is in its “rough” state. This material is not planer-finished and will have no jointed edges.
The abbreviation “S3S” is a description of surface finish, usually pertaining to hardwood species. It stands for “Surfaced Three Sides”, which, as used in Goosebay’s hardwood lumber descriptions, indicates that two faces have been planed, and one edge has been processed with a “straight-line” rip saw, rendering the edge straight and smooth. The other edge … Continue reading Surfaced Three Sides (“S3S”)
“S4S” is an abbreviation for “Surfaced on Four Sides”. It indicates a finish which renders both faces and both edges of a board planer-finished.
“D4S” indicates that the materials have been surfaced on all four sides. NOTE: Dressing will change the actual size of a rough cut measurement. For example, a 4 X 4 piece of lumber dressed on four sides will have an actual measurement of approximately 3.5 X 3.5.
“S1S2E” indicates that the material has been surfaced on two edges and one face, leaving the second face rough. See “S3S.”
Quarter sawn lumber has been cut through the heart of a log and thus the annular rings are perpendicular or 90º to the face of the board. The result is an extremely stable board and can produce spectacular grain patterns (i.e. Ribbon Stripe Sapele or Leopardwood). This is usually more expensive lumber since only a … Continue reading Quarter Sawn Lumber
A board sawn through the heart of a log is called quarter sawn and the annular rings are 90º-60ºto the face, As the log is further sawn, the ring- to-face angle will progressively flatten. A rift sawn, or rift cut, board has an annular ring angle to the face of 60º-30 º. Rift sawn boards … Continue reading Rift Sawn Lumber
