Maple
Description
Maple (Acer spp./Aceraceae). The genus Acer (Maples) is comprised of about
120 species native to temperate and sub tropical regions of the globe. Maples attain
heights of 120 ft with diameters of 3 ft. Some large, trees in natural forests may
have clear trunks of 60 ft. The woods can be separated into Soft Maple and Hard Maple
groups based on hardness and microscopic ray width. Maple sapwood is white to light
brown, while the heartwood is a light red-brown. The species in the Hard Maple group
have fine, uniform texture that is easy to work w/ power tools. It is heavy, strong,
stiff, hard, and resistant to shock, and it has large shrinkage. Sugar Maple is
generally straight grained but the grain also occurs as “birds-eye,”
“curly,” and “fiddleback” grain. The wood of Hard Maple is
hard and heavy and the color of the wood can range from white to reddish brown. It
has a fine, uniform texture that turns well and is resistant to shock and abrasion.
The grain can be straight, curly, wavy or bird's eye. Wood of the Soft Maple group
is similar to wood of the Hard Maple group, but it is less heavy, strong and hard.
Maple wood works well with most tools under most applications. It is rated as
slightly or nonresistant to heartwood decay and is moderately resistant to
penetration with preservatives. It is used for bowling alleys, bowling pins, boxes
and crates, crossties, cutting blocks, dance floors, distillation, flooring,
furniture, handles, lumber, novelties, pallets, paper pulp, piano frames, pulpwood,
shoe lasts, spools and bobbins, turnery, veneer, and woodenware.
