Geographic Origin
Black walnut is native to eastern and central North America.
Workability
Generally works well with hand and machine tools; irregular grain may tear out during planing. Glues and finishes readily; predrilling is useful near knots.
Finish Recommendations
Sand carefully, seal knots or cracks if desired, then use oil, shellac, lacquer, or polyurethane; test finish on an inconspicuous area.
Notable Features
Valued for rich color and figure; visible knots and a crack add rustic character but may affect usable yield.
