CH 17 Woodwork Flashcards
What are the 3 grades of Millwork?
Premium: highest level quality in material, worskmeship, and install
Customs: most common, still produces high quality job
Economy: minimum level of quality
These 3 grades are defined by AWS architectural woodwork standards
What is difference between sift wood and hardwood?
Soft wood refers to timber from evergreen trees (pine, fir).
Hardwood refers timber from deciduous tress (oak, maple)
What 2 forms is timber manufactured into for architectural woodwork?
solid stock: thick piece of lumber used alone to form woodwork component.
Veneer: a thin piece of wood sliced from a log and glued to a backing of particle board or plywood
What are the 3 methods solid stock wood is cut from the log?
Plain sawing: most efficient, less expensive - cathedral characteristic gran
Quarter sawing: grain is more uniformly vertical - fewer defects
Rift sawing: even more consistent vertical grain - most expensive, lots of waste
What are the 5 methods of cutting veneer from the log?
Rotary slicing: mounted ion a lathe and turned against a knife - pronounced grain pattern
Half-round slicing: log cut in half and sliced across growth rings- pronounced grain pattern
Rift slicing: log cut in quarters and sliced across growth rings-Straight grain pattern
Plain slicing:
Quarter slicing
What are some of the common wood joints in millwork?
Half lap, finger joint, scarf, rabbet, dado, dovetail dado, miter, shoulder miter, splinted miter
What is a scribe piece?
An oversized piece of plastic laminate or wood that can trimmed in the field to follow any minor irregularities of the wall
What are the 4 basic categories of cabinet door and drawer front construction?
Flush - face installed flush with face frame
Lipped overlay- door overlaps frame
Flush overlay- front door overlaps face of frame
Reveal overlay- face frame is revealed
What door and drawer front construction is least expensive? Why?
Revel over lay -minor misalignments and sagging are not as noticeable
What are the two basic types of wood paneling?
Stile and rail: traditional type composed of vertical pieces (stiles) and horizontal pieces (rails) enclosing a paneled area
Flush paneling: has a flat smooth surface with the edges butted together or joined with a reveal
What are the 3 ways to match adjacent veneer leaves
book matching - symmetrical grain pattern through flipping every other piece
Slip matching - consecutive pieces side by side
Random matching - random sequence from difference batches of veneer
What are the 3 ways to match veneers within a panel?
running match: simply alternate book matched veneer pieces regardless of leaf widths
- Balanced match: veneers trimmed to equal widths in each panel
- Centre match: an even number of veneer leaves of uniform width so that veneer joint in centre of panel
What are the 3 ways panels can be matched within a room?
Premanufactured: least expensive, field cut around opening, loss of grain continuity
Sequence match: panels uniform width, made for specific job
Blueprint match: most expensive, manufactured to precisely fit the room
How is wood paneling hung on a wall?
Wood seats or aluminum z -clips, allows panels to move as the wood expands and contract and removes need for exposed fasteners
What is high-pressure decorative laminate? ( plastic laminate)
Thin sheet of material made by impregnating several layers of kraft paper with phenolic resins and overlaying the paper with a pattern or coloured sheet and a layer of melamine resin. The assembly is then placed in a hot press to fuse all layers together.
