Workability
Generally excellent with hand and machine tools; machines smoothly, glues well, and takes stains/finishes exceptionally well, though dust can cause mild respiratory irritation.
Finish Recommendations
Penetrating oils (tung or linseed) and wipe-on polyurethanes highlight its rich depth; clear shellac or lacquer works well for fine furniture after light sanding.
Notable Features
Faint distinct nutty aroma when worked; moderate natural decay resistance; high dimensional stability once seasoned properly.
