Finish Carpentry Flashcards
Finish carpentry includes
factory finished items like finished cabinetry & shelving, wall paneling, custom doors; also exterior siding, interior trim, stair framing, door & window framing
Common hardwoods
red & white oak, mahogany, birch, ash, walnut, cherry, poplar, maple
Finish carpentry grading
by Western Wood Products Assn (WWPA): selects (B/better, C/select, D/select), finish (+superior, prime, E), paneling, commons, alternate boards (+ VG = vertical grain)
Lumber cutting
plain sawing = cutting straight across the end of the log, makes ‘cathedral’ shape, least expensive quarter sawing = cutting into quarters, then relatively perpendicular to grain rift sawing = quartering, then radially cutting to stay 90 to saw cut, stays parallel to grain, most expensive
Wood siding
bevel (shingle), shiplap (bad at moisture drip), rabbeted bevel, square edge TNG, v-TNG (good at moisture drip), channel rustic - usu. softwoods bc of natural insect repellent (redwood, cypress, cedar)
Wood stair construction
Wood trim profiles
Architectural woodwork
items made in factories where control is greater than in the field (machines!) - graded by the American Woodwork Institute (AWI): grade I, II, III, also premium, custom, economy grade for construction standards
Types of veneer cuts
plain slicing = plain sawing
quarter slicing = quarter sawing
rotary slicing = oblong shapes (least waste)
half-round slicing = less oblong shapes, as log it cut in half before (less than even plain slicing)
rift slicing = quartered, cut at 15 deg, reduces medullary rays (radial cells in oaks)
source log = flitch
Types of arch woodwork joints
Cabinetry door/drawer types
flush (expensive, need field/shop skill & good materials), flush overlay (millshop needs to be skilled), reveal overlay, reveal overlay
Types of veneer matching
bookmatching = most common, as if a book opened, slip matching = consecutive sliced placed side by side, random matching = no particular sequence, even from separate flitches
running match = bookmatches finish wherever, uneven ends
balance match = each veneer pc is equal in length
center match = ends of panel have equal veneer pcs
Types of veneer panel matching
not matched/premanufactured = least expensive, field cut around openings
sequence matching = panels made for job, attempts to keep grain continuity (loses at openings a bit)
blueprint matching = made for job, at openings, very litte grain continuity lost
Stile & rail panels/doors
vertical = stile, horizontal = rail, may have grooves to hold panel = sticking, center = panel, may have rim around it, held on by wood clips, z-clips or screwed to grounds (battens)
Plastic laminates
common = plam, HPDL, high pressure decorative laminate, phenolic resins w/ melamine resin on top
types of plam = colorthrough (no visible backing), fire-rated (adhesive, substrate less flammable), chemical-resistant (lab-grade, non-corrosive), static-dissipative (for high traffic, electronics, non-conductive), metal-faced (look like metal, v fragile), natural wood (thin veneers of actual wood)
