TRABAJABILIDAD
Aserrado
Although the wood is non-siliceous, it is reported to be abrasive to saws due to pinching and subsequent burning of saw-teeth as a result of residual stresses relieved in the wood.
Corte de chapa rotativa
The veneer produced is of good quality, light and smooth, with curly figure, and can be dried easily.
Chapa tranchada
The veneer produced is of good quality, light and smooth, with curly figure, and can be dried easily.
Maquinado general
It is easy to work with machines and hand tools.
Cepillado
Sharp knives are needed to produce smooth surfaces, if not, grain may pick up badly after planing, especially on radial surfaces. Best planing results are obtained when a 20 degrees cutting angle is used.
Moldurado
Molding operations are reportedly easy, but tension wood, if present, will give woolly surfaces.
Torneado
30
Taladrado
It is easy to bore.
Escopleado, caja y espiga
Mortising is reported to be easy.
Clavado
Nailing properties are rather poor.
Encolado
This species is easy to glue.
Lijado
Sanding properties are rated as fair to difficult.
Sacar lustre
This species has a fair to difficult behavior in polishing.
Facilidad para herramientas manuales
This species is easy to work with hand tools.
