![]() ![]() Board Feet Chart and Calculator Board feet is used as a volume measurement of lumber.Angle Calculator - Carpenter's Square Calculate angles with a straight board across carpenter's square.Material Properties Material properties of gases, fluids and solids - densities, specific heats, viscosities and more.Densities Densities of solids, liquids and gases.Shrinkage will occurs as a result of the moisture loss - typical 3-4% across the grain. Seasoning is the name of the process where moisture content is reduced to the appropriate level for proposed use. Moisture content should be lower than 20% to stop fungal attack. ![]() Mass and density in the Imperial systemĪfter felling, timber will lose moisture to align itself with the atmospheric conditions.Scans/Pictures: Note the pair of pictures demonstrating the use of a bandsaw in resawing a small piece of Leopardwood to fully display the ray flecks in the wood. Silky Oak, Southern (Grevillea robusta).Silky Oak, Northern (Cardwellia sublimis).Additionally, when comparing the endgrain of these two genera, Leopardwood has wider spaced parenchyma bands: approximately 3-4 per mm versus 5-6 per mm with Lacewood. Leopardwood ( Roupala spp.) can usually be separated from most species of Lacewood ( Panopsis spp.) based upon its darker color and higher density. In its vaguest sense, the term “lacewood” is used to describe any wood that displays figuring that resembles lace, (which would technically include Leopardwood). Attempts to identify a specific board macroscopically may be difficult. Two Australian species, Northern Silky Oak ( Cardwellia sublimis), and Southern Silky Oak ( Grevillea robusta) can both look very similar, and are sometimes sold as Australian Lacewood. Sustainability: This wood species is not listed in the CITES Appendices or on the IUCN Red List of Threatened Species.Ĭommon Uses: Veneer, cabinetry, fine furniture, musical instruments (guitars), and turned objects.Ĭomments:Leopardwood is frequently confused with Lacewood, and is sometimes referred to as such. Pricing/Availability: Prices for Leopardwood tend to be medium to high for an imported wood. Leopardwood glues and finishes well.Īllergies/Toxicity: Although there have been no adverse health effects reported for Lacewood in the Roupala genus, several other genera in the Proteaceae family have been reported to cause eye and skin irritation. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information. Workability: Fairly difficult to work because of its high density and tendency to tearout during planing. Rot Resistance: Most species are reported to be very durable regarding decay resistance. ![]() Grain/Texture: Has a fairly coarse texture and straight grain.Įndgrain: Diffuse-porous small to medium pores in tangential rows solitary and tangential multiples of 2-3 deposits in heartwood occasionally present growth rings indistinct very wide rays easily visible without lens parenchyma banded, diffuse-in-aggregates. Like other woods that exhibit the strongest figure in quartersawn pieces, (such as Sycamore), Leopardwood has the most pronounced figure and displays the largest flecks when perfectly quartersawn this is due to the wood’s wide medullary rays, whose layout can be seen the clearest when looking at the endgrain. The wood itself is a medium to dark reddish brown with grey or light brown rays, which resemble the spots of a leopard. Shrinkage: Radial: 3.5%, Tangential: 8.8%, Volumetric: 11.5%, T/R Ratio: 2.5Ĭolor/Appearance: Has a very conspicuous flecking that gives this wood its namesake. ![]()
