Measuring and Marking

 

Measuring and Marking

1. For measurements less than 1', we suggest that you use a rigid metal rule. Unlike a tape measure, a metal rule will lie flat on your workpiece, won't flex, and doesn't have a riveted end.

For measurements greater than 1', a trusty tape measure works fine. Just remember that two tape measures often will give you two different measurements. So, always use the same tape measure throughout the construction of a project. If you and someone else are working on the same project, both of you should use the same brand and length of tape measure. It's a good idea to double-check their accuracy by laying them side by side, as shown above, to make sure that they measure the same.

 

2. When cutting pieces to length, always square one end before you mark anything. Never mark both ends for length before cutting -- you double your chance for error.

3. The riveted end on a tape measure can contribute to inaccuracy if its rivet holes become elongated over time. Unless you're certain that the end of your tape measure is dead-on, you should avoid using it. Instead, line up the 1" mark with the squared end of your workpiece, and then add 1" from the reading on your tape when marking the other end of the cut.
