It is also found in Trinidad, and is a common tree in the Wallaba forests of Guyana. It is also regularly found in the forests of Belize. Heartwood Color Brown Yellow Purple Red Yellow to golden-yellow to orange Greenish to greyish Pale brown Brown Reddish brown Olive-Brown The heartwood has a variegated yellow-brown to olive-brown color, occasionally with clear reddish stripes or streaks. Sapwood Color White to yellow Same as heartwood Not clearly differentiated from the heartwood Different than heartwood Grain Figure Interlocked Straight Stripe (figure) Wavy Crossed Closed Even Irregular Growth rings (figure) Rippled (figure) Spiral Variable (figure) Weak (figure) Texture Medium Medium Fine to medium Luster Lustrous Pronounced Medium to high Natural Growth Defects Trees with trunk diameters above 20 to 25 inches (50 to 62 cm) are often hollow at the center. Natural Durability Durable Durable Susceptible to marine borer attack Resistant to attack from termites (Isoptera) Moderately resistant to termite (Isoptera) attack Moderately durable Very durable Pinworms (ambrosia beetles) often present in the standing tree Pinworms (ambrosia beetles) are commonly present Susceptible to attack from powder post (Lyctid & Bostrychid) beetles Susceptible to attack from termites (Isoptera) Susceptible to attack by subterranean termites Resistant to wood staining fungal attack Resistant to attack from powder post (Lyctid & Bostrychid) beetles Resistant to attack by dry-wood insects Heartwood has high natural resistance to decay Species should preferably be used under protection from the elements since it has little or no resistance to the destructive effects of the weather. Weathering Good Odor Has an odor No specific smell or taste Kiln Schedules Dry at a slow speed UK=C US=T3C2/T3C1 Fr=3 Dry at a moderate speed UK=B US=T2C2/T2C1 Fr=2 T3 - C2 (4/4); T3 - C1 (8/4) US Drying Defects Checking Distortion Severe surface checking Severe end splitting Slight twist/warp Moderate surface checking Moderate end spitting Slight end splitting Severe twisting/warping No surface checking May warp, check and split during degrade Ease of Drying Rapidly Reconditioning Treatement Little degrade Difficult Variable results. Moderate Center of thicker material is decidedly difficult to dry out. Tree Identification Bole/stem form is buttressed Bole/stem form is straight Bole/stem form is cylindrical Comments General finishing qualities are rated as good Blunting Effect Severe dulling effect on tool edges Blunting effect on machining is moderate Boring Fair to good results Easy Responds well to boring operations Carving Fair to Good Results Relatively good response to carving operations Cutting Resistance Fairly difficult to saw Gluing Easy to glue Moderate gluing properties Glues well Difficult to glue Mortising Fair to Good Results Easy to mortise Good mortising properties Moulding Fair to Good Results Easy to mould Fairly easy to mould Movement in Service Medium Dimensional changes in response to fluctuations in atmospheric conditions are moderate after manufacture. Nailing Possible if prebored Pre-boring required Difficult to nail Planing Fair to Good Results Easy to plane Planes well, to a good finish Straight-Grained material is easy to plane. Wood with roey grain may pluck or tear in planing and may require reduced cutting angles for better results. Resistance to Impregnation Permeable heartwood Permeable sapwood Sapwood is extremely resistant Heartwood is extremely resistant Sapwood response to preservative treatment is variable Heartwood responds poorly to preservative treatment Response to Hand Tools Easy to Work Difficult to machine Easy to machine Responds poorly to hand tools Moderate working qualities Routing & Recessing Fair to Good Results Sanding Good sanding properties Screwing Possible if prebored Good screw holding properties Difficult to screw Turning Fair to Good Results Good results Easy to turn Good results Veneering Qualities There is slight to moderate drying degrade and the potential for buckles and splits Moderately easy to veneer Drying degrade is often moderate to severe, with collapse, buckles, and splilts Diifficult to veneer Steam Bending Poor Moderate Very poor Polishing Satisfactory results Good results Poor results Polishes to a smooth finish Staining Finish is generally satisfactory Finish is generally good Strength Properties Modulus of Elasticity (stiffness) = medium Max. crushing strength = medium Max. crushing strength = high Hardness (side grain) = medium Density (dry weight) = 46-52 lbs/cu. ft.
