Heartwood Color Red White Pink Brown Green/grey Yellowish tan Reddish brown Pale grey Occasional brown streaks Sapwood Color Red Brown White Same as heartwood Not clearly differentiated from the heartwood Color not distinct from heartwood Grain Even Closed Straight Interlocked Straight to shallowly interlocked Quartersawn material exhibits a very attractive figure Texture Medium Fine Coarse Non-uniform Coarse Luster Low Lustrous Natural Durability Perishable Non-durable Susceptible to insect attack Non-resistant to powder post beetles Non-resistant to termites Non-resistant to marine borers Non-resistant to termites Non-resistant to pinhole borers Heartwood susceptible to attack by insects Heartwood has very low resistance to decay Odor No specific smell or taste Kiln Schedules T13 - C4S (4/4); T11 - D3S (8/4) US The timber needs to be kiln-dried very slowly in order to avoid twisting and checking To avoid darkening, US schedule T10 - D5S has been suggested for 4/4 stock. Drying Defects Distortion Splitting Checking Rapid drying may cause checking and twisting Ease of Drying Fairly Easy Rapidly Reconditioning Treatement Medium to High Shrinkage Kiln dry slowly to avoid defects Radial - 1.5% Tangential - 3.0% The standing tree is girdled before felling. Shrinkage from green to 12% MC Kiln Drying Rate Rapid Naturally dries quickly Drying rate is fairly rapid to fast Tree Size Tree height is 20-30 m Bole length is 0-10 m Tree height is 30-40 m Trunk diameter is 100-150 cm The trees are reported to develop straight boles that are often 30 to 35 feet (9 to 10 m) long. Trunk diameter is commonly 24 to 36 inches (60 to 90 cm), but may reach 72 inches (180 cm) Comments The timber is described as moderately light with good strength properties Blunting Effect Slight dulling effect on cutting tools Boring Fairly easy to very easy Fair to good results Fairly good results Easy The timber bores readily and easily to produce smooth, clean surfaces, with only slight dulling effect on cutting edges Carving Fair to Good Results Fairly Easy to Very Easy Good results Cutting Resistance Easy to saw Slight dulling effect on saw teeth Easy to saw Gluing Glues well Mortising Fair to Good Results Very Good to Excellent Results Fairly Easy to Very Easy Good mortising properties Moulding Fair to Good Results Fairly Easy to Very Easy Good moulding properties Movement in Service Fair to Good Stability - Medium Movement Excellent Stability - Small Movement Medium The timber exhibits medium movement after manufacture Nailing Fairly Easy to Very Easy Very Good to Excellent Results Fair to Good Results Poor to Very Poor Results Good nailing characteristics Planing Fair to Good Results Fairly Easy to Very Easy Very Good to Excellent Results Responds well to hand and machine tools Easy to plane Resistance to Impregnation Permeable sapwood Permeable heartwood Moderately resistant to preservative treatment The timber is moderately resistant to preservative treatment because of irregular penetration. Treated wood may be used in teredo infested waters.
