Make the grid on tracing paper placed over your working drawings. Then trace the shape from the working drawing, Figure 12-34A. Cut a sheet of heavy wrapping paper for the full-size pattern. Lay out the proper size squares on the paper. Place a dot on the pattern grid where the design crosses it. See Figure 12-34B. Connect the dots to complete the full-size pattern. Cut out the pattern with scissors. Then lay the pattern on the wood and trace around it. Templates A template is a permanent full size pattern used for guiding a tool. For example, you may lay a tem- plate over material to guide a router bit to cut out a shape. It may be made of cardboard, hardboard, or thin sheet metal. Make a template when you intend to use the shape several times. When duplicating irregular curves, use a profile gauge. Refer again to Figure 12-27. This is much simpler than trying to measure the original part to make the pattern. Goodheart-Willcox Publisher Figure 12-33. Full, half, and detail patterns are valuable layout devices.
