<< Lumber Species

Distribution: Australia (Queensland)

General Characteristics: The tree is of tall and straight with heights of 100ft with a trunk diameter of 48". It is Reddish-brown color with a moderately coarse even texture. Wood matures to a brownish color with age. The grain is straight with large rays; rays are especially visible on quartersawn Lacewood.

Weight: Basic specific gravity (ovendry weight/green volume) 0.53; air-dry density 33 pcf.

Working Properties: Good workability but a reduced cutting angle should be used when planing. The rays on quartersawn Lacewood may tend to tear out. Use sharp cutters and a reduced angle of about 20 degrees.

Durability: The wood is reported to have fair resistance to decay and high resistance to wear.

Preservation: The heartwood is reported to be moderately resistant to chemical treatment but the sapwood is permeable.

Mechanical Properties

Bending Strength:
Green: 6,235 psi
Dry: 9,715 psi

Modules of Elasticity:
N/A

Maximum Crushing Strength:
Green: 3,190 psi
Dry: 5,800 psi

Drying and Shrinkage:
Dries slowly and can be difficult to season. Careful air-drying followed by a mild kiln drying is recommended. Checks, distortion, and splitting, especially in thicker stock, are expected. Kiln Schedule T3-C2 is suggested for 4/4 stock and T3-C1 for 8/4. Shrinkage green to ovendry: radial N/A; tangential N/A. Its stability is moderate after drying. Medium movement is to be expected in use.
