Heartwood Color Brown Red Yellow Purple Occasional dark streaks Golden brown or various shades of brown Darkens after exposure Sapwood Color Yellow White Wide Light grayish brown Clearly demarcated from heartwood in old trees Grain Even Straight Interlocked Straight to shallowly interlocked Flat-Sawn timber shows the attractive figure to the best advantage Texture Medium Coarse Medium Greasy feel Even textured Luster Medium Dull Natural Durability Perishable Non-durable Very low natural resistance to decay in ground contact in the tropical regions Susceptible to termite attack Susceptible to attack by powder-post beetle Odor Spicy odor which persists even after the wood is seasoned Kiln Schedules T8-B3 (4/4) T5-B1 (8/4) US Schedule G (4/4) United Kingdom Drying Defects Collapse Internal Honeycombing Possible May distort and end-split slightly during drying Ease of Drying Fairly Easy Slowly Reconditioning Treatement Seasons with little degrade Good drying characteristics Kiln Drying Rate Naturally dries slowly Tree Size Trunk diameter is 150-200 cm Tree height is 30-40 m Tree height is 40-50 m Trunk diameter is 100-150 cm Tree height is 10-20 m The unbuttressed trees are reported to produce straight and cylindrical boles Product Sources Various species in the genus are reported to produce the timber known commercially as Sepetir. Comments Material loss during conversion is rather high because of the wide and unusable sapwood Oily Waste Factor Blunting Effect Severe dulling effect on cutting edges Boring Fairly easy to very easy Carving Fairly Easy to Very Easy Cutting Resistance Easy to saw Difficult to saw Mortising Fairly Easy to Very Easy Moulding Fairly Easy to Very Easy Movement in Service Small moverment after manufacture Good dimensional stability and shows little movement in use Nailing Tends to split during nailing Pre-boring recommended Planing Fairly Easy to Very Easy Woodworking properties usually vary Difficult to work in planing, turning, boring, another machining operations Cutting edges should be kept clean and sharp Clean, finished surfaces Can be planed to a smooth finish Material from swampy locations are somewhat harder and heavier Resistance to Impregnation Permeable heartwood Resistant heartwood Permeable sapwood Resistant sapwood Satisfactory preservative absorption and retention Difficult to treat with presevatives Response to Hand Tools Easy to Work The operation requires sharp cutting edges for best results Routing & Recessing Fairly Easy to Very Easy Sanding Fair sanding qualities Turning Fairly Easy to Very Easy Veneering Qualities Best figure display in veneers is achieved through rotary-cutting Polishing Polishing properties improve considerably after surface treatment Strength Properties Resists wearing, denting and marring fairly well Heavy Fairly hard Density=High Crushing strength = high Compression strength (parallel to grain) = high Bending strength in air-dried condition...is strong Numerical Data Item Green Dry English Bending Strength 9654 14187 psi Density 42 lbs/ft3 Hardness 1529 lbs Maximum Crushing Strength 4861 7669 psi Shearing Strength 1767 psi Stiffness 1603 1908 1000 psi Weight 41 34. lbs/ft3 Item Green Dry Metric Bending Strength 678 997 kg/cm2 Density 673 kg/m3 Hardness 693 kg Maximum Crushing Strength 341 539 kg/cm2 Shearing Strength 124 kg/cm2 Stiffness 112 134 1000 kg/cm2 References Desch, H.
