Processing
| Sawing | power required; fairly difficult; tendency to spring |
|---|---|
| Blunting effect | moderate to high |
| Drying | kiln-drying difficult and slow; quarter sawing and slow drying are recommended U.S. kiln schedule T2·D4 for 25-38 mm (4/4 to 6/4) stock and T2-D3 for SO mm (8/4) stock; British schedule A (25 mm); or kiln schedule for 4 Imm listed below risks of distortion: more: or less high risks of checking: more or less high |
| Machining | difficulties due to hardness and highly interlocked grain (pick up and chipped grain) |
| Gluing | special precaution needed |
| Nailing | good holding of nails; pre-boring necessary |
| Finishing | good |
| Veneering | – |
