4. How to Use a Speed Square

Using a speed square may seem simple, but it requires practice to master. Here’s a detailed step-by-step guide:

Step 1: Measuring Angles

To measure an angle using a speed square, place the square against the edge of the material, ensuring that the 90-degree angle is at the corner. Rotate the square until the desired angle aligns with the edge. Read the measurement from the scale.

Step 2: Marking Cuts

Once you have your angle set, use a pencil to mark along the edge of the speed square. This will give you a clear line to cut along.

Step 3: Checking for Squareness

To ensure that your cuts are square, place the speed square on the corner of your material. If both sides touch the edges of the square without gaps, you have a square cut.

Step 4: Using the Notches for Depth Measurement

The notches on the edge of the speed square can be used to measure depth when cutting. Simply place the square against the material, and use the notches to mark the depth required.

Step 5: Creating Rafter Cuts

To create a rafter cut, align the speed square with the edge of the board and mark the angle. This is particularly useful for roof framing where precise angles are critical.

5. Advanced Techniques with a Speed Square

Once you’re comfortable with the basic uses of a speed square, you can explore advanced techniques. Here are a few:

Creating Compound Angles

To create compound angles for intricate cuts, you’ll need to use both the degree markings and the pivot point effectively. This technique is useful for projects like custom furniture or complex roofing structures.
