The Benefits of Black Walnut Planed Timber

Part of our American Hardwoods range, Timbersource’s made to measure black walnut planed timber is stocked in square edge 4" and wider, generally 4" - 7" boards within a FAS graded pack. A popular choice due to its inherent practicality and premium appearance, this wood is easy to machine, and great for nailing, screwing and gluing. It can also be painted easily, and can be polished to a dazzling finish, though the fact that it dries slowly means that care must be taken to avoid kilning degradation.

Though usually extremely durable, even under conditions in which decay becomes likely, the benefits of black walnut planed timber are mainly enjoyed for either light construction projects, high class joinery, or in the making of quality home furnishings. The heartwood itself is strongly resilient towards decay, although the sapwood can be targeted by powder post beetles. Overall, black walnut is a strong timber with low stiffness, and moderate bending and crushing capabilities. It is also a good choice for steam bending.

What is FAS Grade

The FAS grade, which derives from an original grade "First And Seconds", will provide the user with long, clear cuttings - best suited for high quality furniture, interior joinery and solid wood mouldings. Minimum board size is 6" (152mm) and wider and 8' (2.44m) and longer. The FAS grade includes a range of boards that yield from 83.3% (10⁄12ths) to 100% clear-wood cuttings over the entire surface of the board. The clear cuttings must be a minimum size of 3" (76mm) wide by 7' (2.13m) long or 4" (102mm) wide by 5' (1.52m) long. The number of these cuttings permitted depends on the size of the board with most boards permitting one to two. The minimum width and length will vary, depending on species and whether the board is green or kiln dried. Both faces of the board must meet the minimum requirement for FAS.
