Using a Rafter Angle Square
A rafter angle square is an essential tool for any carpenter or builder. It is used to measure and mark angles on rafters, joists, and other building components. The rafter angle square is also known as a framing square, speed square, or try square.
Step 1: Identifying the Parts of the Rafter Angle Square
The rafter angle square consists of two arms that are connected at one end. The longer arm is called the blade and the shorter arm is called the tongue. The blade has a scale marked in inches along its length. The tongue has a scale marked in degrees along its length.
Step 2: Measuring Angles with the Rafter Angle Square
To measure an angle with the rafter angle square, place the blade against one side of the angle and align it so that it is parallel to the other side. Then, read off the degree measurement from the tongue. This will give you the exact angle measurement.
Step 3: Marking Angles with the Rafter Angle Square
To mark an angle with the rafter angle square, place the blade against one side of the angle and align it so that it is parallel to the other side. Then, use a pencil or marker to draw a line along the edge of the tongue. This will give you an accurate marking of the desired angle.
