ON MEASURING AND MARKING
Quality work starts with careful measurement, accurately marked. These tips will help, as will a No. 2 pencil, whose medium-hard lead leaves a readily visible line.
To draw an accurate line with a ruler, hold a freshly sharpened pencil at an angle, so the point meets the work surface precisely where the ruler does.
Ensure the accuracy of a measurement from an edge by abutting the edge with a stop block, then holding the ruler against it.
Holding a ruler on edge, so its graduations meet the work surface, improves accuracy. With a tape measure, hook the end over one side of the workpiece, then roll its blade to meet the surface.
