12.6 Measuring and Layout Tool Maintenance Measuring and layout tools need very little maintenance. There are few moving parts. However, care is needed during handling and storage of the tool. Some measuring tools, such as framing and try squares, have scales stamped on them. They may become difficult to read over time. If so, wipe across them with a cloth pad containing white paint. Then remove the excess from the surface of the tool with steel wool. The measurements should be readable again. Many tools are plated or painted to prevent rust. If rust does occur, such as on the blade of a try square, remove it with steel wool. Then rub the blade with paste wax. Oil should be used sparingly with woodworking tools because it can stain wood. Moving joints should be rubbed with paste wax for lubrication. However, be careful when lubricat- ing firm-joint tools, such as calipers. This might cause the joint to move too freely. Knives and awls require sharpening. Refer to Chapter 39 for tips on sharpening. The points on dividers, compasses, trammel points, and marking gauges may need to be touched up occasionally. Safety in Action Measuring and Laying Out Workpieces When measuring and laying out workpieces: • Hold sharp points of tools away from you when carrying them. • Cover sharp tool points if you must have them in your pocket.
