OUVRABILITÉ
Sciage
The timber is reported to saw fairly easily.
Coupe de placage de déroulage
It is interesting for peeling, but particularly for slicing.
Placage tranche
It is interesting for peeling, but particularly for slicing.
Effet d'émoussement
The wood is reported to exert a slight blunting effect on cutters.
Rabotage
It is easy to plane, giving a smooth surface.
Moulurage
It is reported to require sharp cutting edges to prevent grain tearing.
Tournage
30
Perçage
End-grain material is reported to require adequate support during boring operations to avoid breaking away.
Clouage
Nailing properties are satisfactory, but pre-boring is recommended since the wood splits rather easily.
Collage
Gluing properties are rated as good.
Finissage
The wood is reported to finish rather well after the grain is well filled.
Cintrage à la vapeur
This wood may bend to a moderate curvature.
Compatibilité avec outils manuels
Response to hand tools is reported to be good, but cutting edges should be kept very sharp to prevent grain from tearing.
