Using the measuring tape, measure the size of your wood thickness together with the blade’s exposed part; else if you fail to take this step and the wood thickness happens to be more than double the blade’s saw exposed then you will have to choose another kind of cutting tool. If you measured and found that the sizes differ then you will have to change the blade, there exist different sizes of blades as 6.5 inches to 8.65 inches diameter blades.

Step 2: Secure the wood onto the stand

Place the wood on the stand after ensuring that the stand size is in union with the wood that you want to cut. Then place the wood in a manner that the area you want to cut is at the far end of the stand. This step is important to avoid injuries when cutting.

Step 3: Mark with the Pencil

Having decided where you want to cut, using the square ruler makes straight mark lines using the pencil. Make sure that you mark all around the wood for accuracy purposes. After creating your line use the measuring tape and measure from one end of the wood to every line. Make sure that all the lines are at the same distance from the end of the wood.

Step 4: Adjust the blades of the circular saw

The cutting process starts from one side of the marked line and doesn’t force the saw forward when cutting. Hold the wood with one hand and with the saw blade riding through it as you cut.

Step 7: Flip and Finish

After you are done cutting one side of the, then rotate the wood at an angle of 180 degrees as you cut the other marked line. Once you complete this rotation now re-clamp your workpiece to grab your saw again. Do this step for all the marked lines.

Step 8: Storing your circular saw

Storage is also one of the most essential steps, if stored wrongly then the lifespan of your saw will be reduced by far therefore after use you should wipe the saw, remove the blades and wipe them and ensure every piece is dry before attaching them back.
