Workability
Sawing
The timber is reported to saw fairly easily.
Rotary Veneer Cutting
It is interesting for peeling, but particularly for slicing.
Sliced Veneer
It is interesting for peeling, but particularly for slicing.
Blunting Effect
The wood is reported to exert a slight blunting effect on cutters.
Planing
It is easy to plane, giving a smooth surface.
Moulding
It is reported to require sharp cutting edges to prevent grain tearing.
Turning
30
Boring
End-grain material is reported to require adequate support during boring operations to avoid breaking away.
Nailing
Nailing properties are satisfactory, but pre-boring is recommended since the wood splits rather easily.
Gluing
Gluing properties are rated as good.
Finishing
The wood is reported to finish rather well after the grain is well filled.
Steam Bending
This wood may bend to a moderate curvature.
Response To Hand Tools
Response to hand tools is reported to be good, but cutting edges should be kept very sharp to prevent grain from tearing.
Substitute Species
Teak (Tectona grandis)
