CHARACTERISTICS |
| GENERAL CHARACTERISTICS: |
Wood light tan to brown, hard and heavy, grain fairly straight to roey; texture médium. Odor and taste not distinct. |
| WEIGHT: BASIC SPECIFIC GRAVITY: |
(oven-dry weight, green volume) 0.55 (35 Ib. per cu. ft.) |
| WEIGHT: AIR DRY SPECIPIC GRAVITY: |
0.58-0.77 (36 to 48 Ibs. per cu. ft.) |
| DRYING AND SHRINKAGE: |
Timber is somewhat difficult to season without degrade due to checking and collapse. Quarter-sawing ¡s recommended and combina-tion of air drying and kiln drying may be used to reduce degrade.
Total shrinkage from green to oven-dry as % of green size ¡s: RADIAL: 6.7%, TANGENTIAL: 14.1%, VOLUMETRIC: 19.9%. |
| NATURAL DURABILITY AND PRESERVATIVE TREATMENT: |
Strong, but not durable where exposed to weather, sapwood permeable, heartwood extremely resistant to ¡mpregnation. |
| WORKING QUALITY: |
Timber ¡s fairly difficult to work due to inter-locked grain. Lumber from young trees tends to twist and warp badly. Good machine finish and polish can be obtained. Glues, satisfactorily. |
