HARDNESS (JANKA): 1010 DIMENSIONAL STABILITY:

Average – American black walnut has a dimensional stability factor of 5.5 percent (radial) and 7.8 percent (tangential), meaning this species may shrink/swell up to 7.8 percent of its given width, depending on how it’s cut, when going from green (30 percent MC) to oven-dried. DIMENSIONAL CHANGE COEFFICIENT: .00190 (radial), .00274 (tangential) SPECIFIC GRAVITY: .55 NAILING: No known issues, but can sometimes have a tendency to split the tongues dependent on fastener placement and grain orientation. SANDING: A softer species that sands satisfactorily. It can be difficult to sand because of the density, which can make sander marks show more than on some woods. Some people are very allergic to walnut dust; respirators are highly recommended when sanding. Normally required to bring sanding sequence to a higher grit to minimize visible scratches. When sanding walnut that has been installed along with harder, denser species, it is important to sand on diagonal and/or use a hard plate or multi-disc sanders to minimize dish out. Staining walnut can minimize long-term effects of the inherent lightening properties to which walnut is prone.
