Appearance of American Soft Maple Timber
Soft Maple is visually similar to Hard Maple, featuring greyish-white sapwood and heartwood that ranges from light to dark reddish brown. Its colour can vary significantly depending on the region where it is grown. The timber is typically straight-grained, although a distinctive wormy figure may occur, adding unique character that is not regarded as a defect. Soft Maple's ability to mimic other species, such as cherry, when stained enhances its appeal for decorative projects.
Applications of American Soft Maple Timber
American Soft Maple is prized for its flexibility and is used in a variety of interior applications. Common uses include furniture, cabinetry, veneer panels, mouldings, and doors. Its excellent workability makes it a popular choice for woodturning and carving, and it is often used in the construction of musical instruments. Its ability to take stain and polish to a high finish also makes it suitable for decorative purposes.
Workability of American Soft Maple Timber
Being about 25% softer than Hard Maple, Soft Maple is significantly easier to work with. It machines, nails, screws, and glues well, and its fine texture allows it to achieve a smooth, polished finish. Soft Maple also responds well to steam bending, adding to its versatility. While it dries slowly, it maintains good dimensional stability, making it reliable for various applications.
Durability and Maintenance of American Soft Maple Timber
Soft Maple is less dense than Hard Maple, offering moderate bending and crushing strength, with lower stiffness and shock resistance. While not as hardwearing as Hard Maple, it remains a durable choice for many interior applications. Proper surface treatment, such as staining or polishing, enhances its appearance and longevity.
Origin and Availability of American Soft Maple Timber
Native to North America, American Soft Maple is sourced from both the eastern United States and the Pacific Northwest. Its widespread growth ensures a steady supply, and availability in Australia is expected to increase as demand grows. Consult Kosny Timber for specific regional options and grades.
