The triangular building square was initially designed in 1925 by Albert J. Swanson. It is a fast and accurate method of measuring roof beams. Today this tool is widely used by carpenters in their projects, be they small or large. The triangular square has marked gradations in degrees and helps to simplify the organization of the material and the cutting of the wood. This tool is very useful and saves a lot of time for those who use it as it allows you to detect the data you need without having to take measurements and make complicated calculations. Use this square to draw straight lines and mark corners in construction work.
Steps
Step 1. Draw straight lines
Use the square to mark lines with exact 90 ° angles on the wood. Hold the tool steady against the table. The border will facilitate alignment. Use the sides to mark the lines on the wood. Use the squares to locate and mark nails, floor joints and to position the star posts.
Step 2. Line up the wood at the exact angle
If building cabinets, boxes, or other similar furniture, hold the square against the wood to measure angles before cutting or adding other pieces.
Step 3. Draw a 45 ° line
Place the square against the board and mark the position of the diagonal edge to create a 45 ° line. As in an isosceles triangle, the angle of the diagonal is exactly 45 °.
Step 4. Read and mark the corners
Look for the pivot point in the corner of the team. Each line along the diagonal represents 1 degree and ranges from 0 to 90. Hold the pivot point against the board and adjust the square until the gradation lines up with the edge of the board. Use a pencil to draw a line along the team.
Step 5. Mark a parallel line
Hold the square against the edge of the wood and put the tip of the pencil in the hole to measure the number of cm needed. Slide the square along the wood with the pencil in the hole. You will draw a straight line parallel to the edge of the wood.
Step 6. Drive a portable circular saw
Place the square on the board to be cut. Slide the base of the saw against the square and cut. The saw will cut evenly and accurately because the square is thicker than a metal one or a combined square.
