Chapter 17 - Architectural Woodwork Flashcards
_______ is custom, shop-fabricated millwork built primarily of lumber and used for interior finish construction and specialty furnishings
architectural woodwork
architectural woodwork is sometimes referred to as
millwork
architectural woodwork can have what incorporated into the item?
ornamental metal, tile, stone, glass, leather, and fabric
three levels of millwork
premium, custom, and economy
premium millwork
highest level of quality in materials, workmanship, and installation
custom grade millwork
most common and still high quality
modular casework
prefab cabinets that are selected from manufacturer’s standard line. used in residential kitchens and baths, laboratories, schools, and other areas where quality cabinets are required but custom construction is not
raw material for architectural woodwork is broadly classified as either ____ or ____
softwood or hardwood
softwood
evergreens- pine and fir
hardwood
deciduous- oak and maple
timber is manufactured into two forms for use in architectural woodwork:
- solid-stock lumber
- veneer
solid stock lumber can be cut in three ways
plain, quarter, rift
plain sawn
most efficient use of the log and is the least expensive of the three methods cathedral patterning
quarter sawn
produced by cutting the log into quarters and then sawing perpendicular to a diameter line.
the pattern is more uniform.
tends to be twist and cup less, shrink less in width, hold paint better, and have fewer defects than plain sawn
rift sawn
most consistent vertical grain because the saw cuts are always made radially to the center of the tree.
there is more waste
can you get any type of cut for any type of wood?
no
not all types of lumber cutting are available in all species
veneers can be cut in five ways
- plain slicing
- quarter slicing
- rotary slicing
- half-round slicing
- rift slicing
plain slicing and quarter slicing are produced in the same way as is with solid stock, except
the resulting pieces are much thinner
quarter slicing (veneer)
produces a more straight-grained pattern than plain slicing because the cutting knife strikes the growth rings at apprximately a ninety degree angle
rotary slicing
the log is mounted on a lathe and turned against a snife, which peels off a continuous layer of veneer
produces a very pronounced grain pattern that is often undesirable in high quality woods
half-round slicing
similar to rotary except the log is cut in half, and the veneer is cut slightly across the annular growth ringspronounced grain pattern sim to both rotary and plain slicing
rift slicing
like quarter slicing, it results in a straight-grained pattern. commonly used with oak to avoid perpendicular markings
