A study of methods of piling silk-oak in Hilo, Hawaii, showed that drying was more rapid and degrade less in piles spaced 5 feet than in those spaced 1 foot. Roofing had no influence on drying rate or degrade due to drying. Principal drying defects were blue stain of sapwood, end splitting, and surface checking.

Shrinkage, specific gravity, and hardness of two shipments of silk-oak (Grevillea robusta) from Hawaii were evaluated to provide basic information pertinent to the use of the wood for cabinet and furniture purposes. The wood resembles Hawaii-grown shamel ash (Fraxinus uhdei ) in the properties evaluated. Shrinkage compares well with that of black cherry, silver maple, or red lauan. Side hardness of green wood considerably exceeds that of black cherry and paper birch, but that of air-dry wood is closely comparable to that of those two Mainland species. End hardness of green wood compares well with that of black cherry, but that of air-dry wood more closely resembles that of paper birch Density of the wood is generally comparable to that of paper birch.
