Peruvian walnut, which grows throughout central and south America, is an imported hardwood from the same species of trees as black and English walnut. The grain is typically darker than others from within this group, but can have streaks of lighter red and oranges, throughout. These trees tend to grow taller and straighter than its American counterparts, and thus the grain tends to have less variation than other offerings. Grain is generally straight with a slightly course texture. It works similarly to other walnuts, with the caveat that the more uniformed grain will reduce tear out found in the higher figured domestic versions. It turns, glues, and finishes well, and has been used for flooring, cabinetry, mill work, musical instruments, and furniture. Peruvian walnut has a Janka rating of 950 and weighs 3.5 pounds per board foot.
VARIATIONS AND OPTIONS
4/4 refers to lumber that was cut at 1 inch thickness
15/16ths has been skip planed (a majority of the surfacing work has been done, there may be a few spots that are still rough, but the grain of the particular piece of wood should be visible)
13/16ths is commonly called finish planed. This should be ready for sanding and finish
Ripped 1 edge is lumber that has been run through a straight-line rip saw. This allows for easy squaring on a table saw.
Sanded refers to a select few lumber options that have been run through a belt sander and are 100% finish ready.
5/4 lumber was sawn at 1.25 inches in thickness.
6/4 lumber was sawn at 1.5 inches in thickness.
8/4 lumber was sawn at 2 inches in thickness.
