Grain Pattern
Mostly straight, with mild cathedral and irregular grain; broad tangential-sawn face and some surface tearout are visible. No clear figured pattern can be confirmed.

AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.
- Wood Age Estimate
- The board’s age cannot be determined from the photograph; weathering indicates exposure, not necessarily old wood.
Common Uses
Furniture, cabinetry, flooring, veneer, gunstocks, turning, carving, and architectural millwork.
Geographic Origin
Eastern and central North America, especially the Midwest and Appalachians.
Workability
Generally machines and sands well, but changing grain can cause tearout; predrilling improves fastening and standard adhesives work well.
Finish Recommendations
Sand carefully and use wiping oil, shellac, lacquer, or polyurethane; a conditioner or washcoat can reduce uneven absorption.
Notable Features
Moderate density, attractive brown color, good dimensional stability, and occasional curl or crotch figure.
