What happens here

To ensure accurate cuts, first mark your desired measurement on the wood using a pencil and tape measure. Then, identify the side of the line you want to keep (the finished piece) and the side you want to discard (the waste side). Place an 'X' on the waste side. Position the saw blade so that its teeth are aligned just outside the marked line, on the waste side, ensuring the kerf removes only the waste material and not part of the finished piece.

Goal: Correctly mark and position the saw blade to achieve accurate cut lengths

That's because your blade isn't infinitely thin. Every time you make a cut, your blade removes material. That width is called the kerf. So, when I mark 12 in, this line isn't where I want the center of my blade. This is the side I want to keep, and I put an X on the side I want to get rid of. Put the edge of my tooth on the waste side of the line. But, here's where things get interesting. Not every blade has the same kerf. Different blades can have different kerfs. Changing blades can change exactly how much material disappears. I take this 12-in piece and I want to divide it into
