12.4.6 Layout Rod A layout rod is a record of often-used distances. Plan to make one for standard cabinets you produce. It eliminates the need to measure repeatedly with a rule. A layout rod can also help with machine setups. The rod is marked with important cabinet dimensions, Figure 12-35. These may be the loca- tion of shelves, doors, and joints. Measurements are marked full size. Make the rod slightly longer than the greatest dimension of the cabinet. The rod can be used for height, width, and depth measurements. A rod is made of 1 × 1 or 1 × 2 lumber. It is sur- faced on all four sides. One side may contain width measurements. A second side may contain height measurements. Other sides are used for depth and other important dimensions. 12.4.7 Story Pole Similar to a layout rod, a story pole is used to mark the exact locations of items found in a room. It is usually made of 1 × 3 lumber and is as long as necessary (up to the room width). A second pole is made equal to the height of the room, or the top of the highest cabinet. In addition to marking cabinet locations on the story pole, mark all other items in the room, such as electrical outlets, switches, doors, windows, vents, radiators, plumbing, and light fixtures. 12.5 Digital Measuring Devices There are many digital measuring devices avail- able. Lasers are now commonly used on jobsites for measurement. They can be used to quickly and accu- rately record the dimensions of a space. Electronic calipers can switch from inch to metric with the push of a button. See Figure 12-36. Machine accu- racy and repeatability is now so precise that cabinet- makers frequently measure to within thousandths of an inch. As parts are created, they must be measured to ensure accuracy so assemblies will fit together properly. Some digital measuring devices have the ability to send data to a computer for collection. See Figure 12-37. This record of parts in production can help resolve any machining issues that may occur. Goodheart-Willcox Publisher Figure 12-35.
