5 CO_Q0_TLE-Carpentry 7/8_Module 5 Selecting the measuring instruments or tools is one of the carpenter’s routines which require know-how, initially, in choosing what measuring tools to use in a specific carpentry work. Through the knowledge and skills you possess, you can easily perform the activities not only in the creation of projects but also in ensuring the accuracy of measurements for the dimensions of your output. Practically, ample know-how on these measuring equipment or tools can give you benefits. These benefits are efficient in the preparation of materials and accuracy of work. They enable you to successfully produce quality output in your future ventures in carpentry. To start mastering this lesson, let us have an initial activity which can help you think about the categories of the tools and equipment. What’s New Congratulations, learners! You have proven that you really learned a lot in your previous lesson. Now, you will be harnessed with new skills in identifying linear measuring instruments appropriate for a given tasks. Do you have any idea about the linear measuring instrument and their uses? Let us take a look on how much knowledge you already have doing this activity. Are you excited, learner? So, get it on! Activity 2- Match the Tools Directions: Identify the correct linear measuring instrument in Column A that is appropriate to measure the materials in Column B. Write only the LETTER of the instrument. Notes to the Teacher For this lesson, learners might be exposed to the different materials which can be harmful to handle. Proper guidance of the teacher is advised. Ensure that the learners wear their protective gears before bringing them to actual performance using the materials. This precaution is made by the teacher when the learner will use actual tools.

7 CO_Q0_TLE-Carpentry 7/8_Module 5 What is It Wow! You have successfully identified the correct linear measuring instruments. This time, you will learn more about the linear measuring instruments and their uses. Please learn it by heart. Types of Linear Measuring Tools 1. Pull-push rule – used for measuring long pieces of stock. 2. Zig Zag Rule – a folded measuring tool. 3. Ruler – used for measuring short pieces of stock. 4. Caliper – used for measuring diameter. 5. Try Square – used for checking flatness and squareness. 6. Meter Stick – a measuring device which is up to one (1) meter in length, used to measure dimensions. 7. Compass – used for scribing arcs and circles. 8. Protractor – used for measuring and laying out angles.
8 CO_Q0_TLE-Carpentry 7/8_Module 5 Handling of Measuring Instruments / Tools A. DOs 1. Wipe measuring tools/instruments before returning them to the storage room. 2. Oil the movable parts of the measuring tools such as zigzag rules, calipers, dividers and compasses to avoid stock-up. 3. Make sure that grits like sand do not get inside the housing or case of a pullpush rule to avoid wearing off of the graduations. 4. Check the lock of a pull-push rule if it is working. B. DON’Ts 1. Do not wipe off edges of the steel tape of pull-push rule with bare hands to avoid injury. 2. Do not pull the steel tape of pull-push rule too much to avoid its coil spring from damage. 3. Do not use the caliper as tongs. Measuring Instrument – a device used for measuring physical quantities. Linear Measurements – a distance between two given points in an object or in the material used for carpentry. Measurement – the size, length, or dimension of something as established by measuring. Linear Measure – a measurement of length. An example of linear measure is using meter stick or stick yard to find out the length of the table. Linear measure
9 CO_Q0_TLE-Carpentry 7/8_Module 5 Units of Linear Measurements Study the chart below: U.S. Customary Units/ English System International System/ Metric Units Units Abbreviations Units Abbreviations inches foot yards miles (in) (ft) (yd) (mile) millimeter centimeter meter kilometer (mm) (cm) (m) (km) With linear measuring instruments like ruler, meter stick, and tapes, you can take measurements of materials that you need in your carpentry projects. You can also obtain the linear measure of tools such as hammer, screwdrivers, plier, and more. The example below illustrates the placements of the ruler along the hammer to measure its length. To measure the length of a hammer, place it close to the ruler as shown above. Make sure that the tip of the object is aligned with the zero (0) marking on the ruler to which the measurement of an object begins. Then, mark the ruler where the other tip of the object ends. Things to Remember 1. There are nine (9) linear measuring instruments or tools that can be used in measuring various materials. These linear measuring tools are caliper, compass, divider, meter stick, protractor, pull-push rule, ruler, try square, and zig zag rule. 2. There are several things to remember on how to take good care of the measuring instruments. These are the do’s and don’ts in handling the linear measuring tools. Through these guides, we can be able to protect the tools from any mis-use or damage. Thus, we can prolong its usefulness. 3.
