TRABAJABILIDAD
Aserrado
It saws easily, with a slight tendency to produce woolly surfaces.
Corte de chapa rotativa
It is interesting for peeling.
Chapa tranchada
It is interesting for peeling.
Pérdida de filo_romado
The wood may have a moderate blunting effect on cutting tools.
Maquinado general
Machining operations are reportedly easy, but it has a tendency to produce woolly surfaces. It behaves better when seasoned.
Cepillado
Seasoned material planes well to yield relatively smooth surfaces.
Clavado
Good nail-holding properties.
Encolado
The material is reported to glue easily.
Lijado
Sanding qualities are reported to improve in seasoned wood.
Acabado
It needs care in finishing, because of the resin present in the wood.
Doblar al vapor
This species has moderate steam bending properties.
Facilidad para herramientas manuales
Dry timber is reported to work well with hand tools.
