TRABAJABILIDAD
Aserrado
Peltogyne is reported to be moderately difficult to saw. Tools usually require frequent sharpening.
Corte de chapa rotativa
This species is interesting for slicing, thermal treatments are recommended.
Chapa tranchada
This species is interesting for slicing, thermal treatments are recommended.
Pérdida de filo_romado
Cutting tools may be gummed up if they are not very sharp. Blunting is rated as moderate.
Maquinado general
Peltogyne is reported to be moderately difficult to work in most machining operations including planing, turning, boring, and molding. They respond rather poorly to ordinary tools, and working with dull cutters may cause the wood to heat up.
Cepillado
A reduction of the cutting angle to 15 degrees is required, when wavy or interlocked material is present, to obtain satisfactory results in planing.
Torneado
30
Taladrado
Boring is difficult, the wood has a tendency to burn
Escopleado, caja y espiga
To get good results in mortising end support is needed.
Clavado
The wood requires to be pre-bored, but nail-holding capabilities are reported to be good.
Encolado
The material is reported to be easy to glue.
Lijado
The material is reported to be fairly difficult to sand.
Acabado
Organic solvents remove the characteristic purple color. To preserve the natural color, wax finishing is recommended.
Barnizado
For this species water-based finishes are reported to hold color better. The use of spirit finishes may remove the purple coloring in the wood.
Sacar lustre
Polishing properties are reported to be rather good.
Doblar al vapor
The wood steam bends fairly well.
Facilidad para herramientas manuales
Response to hand tools is reported to be only fair.
