Read blueprints, drawings, or written specifications to determine sizes and shapes of patterns and required machine setups. Lay out patterns on wood stock and draw outlines of units, sectional patterns, or full-scale mock-ups of products, based on blueprint specifications and sketches, and using marking and measuring devices. Verify dimensions of completed patterns, using templates, straightedges, calipers, and/or protractors. Set up, operate, and adjust a variety of woodworking machines such as bandsaws and lathes to cut and shape sections, parts, and patterns, according to specifications. Trim, smooth, and shape surfaces, and plane, shave, file, scrape, and sand models to attain specified shapes, using hand tools. Fit, fasten, and assemble wood parts together to form patterns, models, or sections, using glue, nails, dowels, bolts, and screws. Correct patterns to compensate for defects in castings. Construct wooden models, templates, full scale mock-ups, jigs, and/or molds for shaping parts of products. Compute dimensions, areas, volumes, and weights. Mark identifying information such as colors or codes on patterns, parts, and templates to indicate assembly methods. Finish completed products or models with shellac, lacquer, wax, or paint. Glue fillets along interior angles of patterns. Select lumber to be used for patterns. Repair broken or damaged patterns. Maintain pattern records for reference. Inventory equipment and supplies, ordering parts and tools as necessary.
