What are the Skills and Practices to be Developed in Marking and Measuring in Doing Woodworks?
Now that we are already familiar with the uses of tools in woodworking, we are now ready to do some wood works. It is essential to a mechanic or carpenter to know all his/her tools prior to the job he will be doing. Tools must be used properly where it was intended to. In measuring and marking there are some practices that a carpenter must kept in kind. Accurate measurements and marking properly is one of the most important processes to have a good work in the shop.
Below are the following practices and skills that a carpenter must have in order to maintain the quality of their jobs.
- The ruler must be put on the end so that the graduation touches the work that is being marked to have an accurate measurement.
- It is a good practice if you will not be raising the ruler on and off the board as you are measure a straight line.
- Place the ruler across the board at an angle in locating the middle of the board so that a major division coincides with the edges of the board. The midway b/w the two major divisions of the ruler is the middle part of the board.
- It is a good idea to think of a measurement as a major fraction subtracted a small fraction in measuring fractions.
- Never drop it as the try square is use in accurate measurements.
- Using try square as a hammer is not a good idea.
- Handle must be held fine against the working surface when squaring the work.
- If you have doubts if the try square is not accurate and straight, examine it first by putting the equipment in a straight edge by marking a line across the board. And if it doesn’t match the square is not true.
1. It is used in checking and laying angles and bevels
2. Protractor is used in measuring and laying an angles
Marking with a pencil or a knife:
1. You should be close to the edge and use try square or ruler in marking using a pencil.
2. In cabinet making it is preferred to use a knife and a metal ruler to have accuracy.
3. Pencil is used for ordinary works, use a hard pencil, with sharp and longer mark fo it is better than soft one.
- The gauge spur must be filed to a sharp point and should protrude through the beam about 1/8 in. to make a fine line.
- Ruler will be use in checking the setting
- In the line where head is being gauged, it must be held firmly against the working edges.
- Roll the gauge slightly forward to allow spur to drag and prevent gouging, this must be with a slight angle
- Ordinary ruler and a pencil can be used in gauging if you don’t have gauge.
- Thumbscrew must be loosened until the legs are on its place in setting a pair of dividers before tightening it.
- In measuring equal distances divider is used.
