Locust

Scientific Name: Balata ­ Hymenaea Courbaril – (Family: Caesalpiniaceae)
A.T.I.B.T. Standard Name: Courbaril
Other Names: - Copalier, Algarrob, Gaupinal, Jatoba

THE TREE

Locust is a large, nearly evergreen tree growing to 130 feet high and 5 feet in diameter; but normally it is less than 100 feet high and 2-4 feet in diameter. Boles measure 60-80 feet in height.

WOOD APPEARANCE

Locust heartwood is light brown to brown often with dark streaks and at times may show a golden luster. The sapwood is of whitish grey color, which is sharply defined. Locust grain is usually interlocked, but is occasionally straight; the texture medium to coarse. The wood is particularly attractive, resembling sugar maple and having a high lustrous sheen marked with scattered lines.

PHYSICAL PROPERTIES

Locust is very hard and strong, with good mechanical properties. Locust is also especially elastic.

Weight: In the green condition the timber weighs 70 pounds per cubic foot, and 57-62 lbs/ft3 (910-1000 kg/m3) when air-dry.

Specific Gravity: Air-dry wood averages about .84 based on air-dry volume and weight, and averages .67 based on green volume and oven-dry weight.

NATURAL DURABILITY

Locust is very resistant to decay.

TIMBER PROCESSING

Seasoning: Dries readily without distortion or splitting.

Working/Machining: Moderately difficult to work due to the high density of the wood. Planes and turns without difficulty. Good bending to steam process.

Assembly: Glues well. The wood is difficult to nail but has good screw-holding power.

Finishing: Finishes smoothly. Polishes and varnishes without difficulty.

USES

Locust provides as a good wear-resistant surface, which takes a fairly good polish. Locust is a wood of decorative appearance suitable for use in the manufacture of high-grade furniture, cabinet work, decorative joinery and veneer. It is also for ship-building, general construction, flooring, cross-beams, and the high shock resistance makes it ideal for sporting goods and tool handles.

SUPPLIES

Occurs widely but not abundantly in Guyana forests. Regular supplies in modest quantities are available.
