Verify dimensions or check the quality or fit of pieces to ensure adherence to specifications. Produce or assemble components of articles, such as store fixtures, office equipment, cabinets, or high-grade furniture. Measure and mark dimensions of parts on paper or lumber stock prior to cutting, following blueprints, to ensure a tight fit and quality product. Set up or operate machines, including power saws, jointers, mortisers, tenoners, molders, or shapers, to cut, mold, or shape woodstock or wood substitutes. Establish the specifications of articles to be constructed or repaired or plan the methods or operations for shaping or assembling parts, based on blueprints, drawings, diagrams, or oral or written instructions. Attach parts or subassemblies together to form completed units, using glue, dowels, nails, screws, or clamps. Reinforce joints with nails or other fasteners to prepare articles for finishing. Install hardware, such as hinges, handles, catches, or drawer pulls, using hand tools. Trim, sand, or scrape surfaces or joints to prepare articles for finishing. Match materials for color, grain, or texture, giving attention to knots or other features of the wood. Cut timber to the right size and shape and trim parts of joints to ensure a snug fit, using hand tools, such as planes, chisels, or wood files. Perform final touch-ups with sandpaper or steel wool. Bore holes for insertion of screws or dowels, by hand or using boring machines. Repair or alter wooden furniture, cabinetry, fixtures, paneling, or other pieces.
