Colors: the heart isReddish brown, Yellowand the sapwoodWhite to yellow, Yellow.The grain isVariable (figure), the textureFine to mediumand the lusterSlightly lustrous The luster is low to medium

Natural durability: Resistant to attack from termites (Isoptera), Very durable

Odor: No specific smell or taste

Kiln Schedules: Kiln Schedule G (4/4); United Kingdom

Drying Defects: Slight twist/warp, Splitting

Ease of Drying: Moderately Difficult to Difficult

Tree Identification: Bole/stem form is unknown

Comments: General finishing qualities are rated as good Machiche is a potential substitute for applications where a dark-reddish wood, such as Mahogany is required

Boring: Moderately easy

Cutting Resistance: Easy to saw

Nailing: Difficult to nail, Pre-boring recommended

Planing: Planes to a satisfactory finish

Resistance to Impregnation: Sapwood is resistant Most species in the genus are rather difficult to treat with wood preservatives

Response to hand tools: Difficult to machine

Sanding: Good sanding properties

Veneering qualities: Veneers easily, Veneers moderately easy

Steam bending: Moderate

Turning: Turns with moderate ease

Polishing: Good; Staining: The wood takes finishes well, except polyurethane. Finishing is reported to highlight irregularities in the grain to make the normally dull wood rather attractive ;
