Although cabinetmakers generally prefer hardwoods, many fine pieces of
furniture have been built with softwood. There are good reasons for using
hardwood's less expensive cousin: Softwood is generally more readily available
than hardwood, and is easy to work.For more, if you want to know more about the
softwood balsa, then you
can take a look into our website. You know that the balsa wood can make your
different kinds of model.
Pine is one of the most popular choices of cabinetmakers. Its varieties
include Eastern white pine, Southern yellow pine and species from the West, such
as sugar pine, Idaho white pine and ponderosa pine. Douglas-fir, another Western
softwood, is also gaining popularity as a cabinet wood. Sitka spruce and Western
larch are two other good choices.
For cabinetmaking, you should restrict yourself to grades of softwood.
Remember that softwoods are generally sold S4S-that is, planed smooth on both
faces and jointed on the edges. And they are graded based on the board's best
face after surfacing.
Unlike hardwoods, softwoods are graded differently depending on the species;
the grade for a California redwood board, for example, does not apply to a piece
of ponderosa pine. You can obtain information about softwood grading standards
from the American Lumber Standards Committee in German town. Maryland.
Softwood grading takes both strength and appearance into account. Three grade
categories-Select, Finish and Common-are often used for woodworking. Select and
Finish grades must be clear of defects, while boards in the Common grades may
contain defects such as tight knots. Select and Finish stock are seasoned to a
moisture content of 15 percent or less. Common boards, used mainly in
construction and home building,g4nmkvkz may have up to a 19 percent moisture
level. The quality of Common grade boards is further divided into categories 1
to 5, with the highest number corresponding to the lowest grade.
Some boards display a grade stamp. The stamp displays information about the
species, moisture content when surfaced and grade of the stock. To avoid marring
their appearance, however, 1-inch-thick boards in the better grades are often
not stamped after surfacing. The stamp may also be missing from lesser grade
boards that have been cut into shorter lengths by retail lumber dealers.
Keep in mind that softwood is sold according to nominal size, or green
dimensions, which is different from a board's actual size. A2-by-4,for example,
actually measures 1.5 by 3.5 inches.Here to know more about end
