Suitability for Peeling: Not recommended or without interest ^ref
Suitability for Slicing: Good ^ref
Sawing Machining Notes: Careful polishing is necessary due to interlocked grain. ^ref
Assembly Nailing Screwing: Good but pre-boring necessary ^ref
Assembly Notes: Tends to split with nailing. High specific gravity: important that gluing be performed in compliance with the code of practice and instructions for the glue used. ^ref
Additional Notes: Its unpleasant odour may limit the use of this timber. For furniture end, uses, filling, and varnishing are necessary ^ref
