Measuring Tools and How They Work
|
|
|
GOAL: To understand the four types of woodworking measurements and the tools designed to assess them.
As woodworkers we need to be able to measure four things: alignment (straightness), planar accuracy (twist), angular accuracy (angles) and linear dimension (length). Of the tools we use for our measurements, only the dimension measures are calibrated so that we can say the measurement is too small or too large and by how much. The rest tell us right or wrong but not by how much. In other words, we rely on our eyes to gauge a given measurement. In this lesson, you will learn the five primary types of measuring tools and how they serve as important visual aids. |
