NB Table – Walnut
Many species of walnut exist throughout the world, but the most common species in North America is Black Walnut. The tree grows abundantly across the continent, but doesn’t yield as much wood as other larger species, such as oak and maple. Black Walnut’s favorable working characteristics and rich color make it one of the most valued domestic lumbers. The heartwood of the tree ranges from dark tan to a deep chocolate brown, sometimes with streaks of purple and green hues. The sapwood is a very pale yellow, and can add a nice touch of contrast when incorporated in a project.
Black Walnut is semi-ring porous, with medium-sized pores throughout and larger pores at the edge of its growth rings. The wood has a low level of shrinkage when drying, and suffers very little seasonal movement. At 1000lbf Janka, the wood isn’t exceptionally hard, but can stand up to a fair amount of abuse. Walnut is straight-grained and remarkably easy to work with in almost every application. The wood cuts and sands evenly, finishes nicely, glues well, and can be steam-bent with stable and predictable results.
