Understanding Stair Stringers

Before diving into the cutting process, it's important to understand what stair stringers are and their role in staircase construction.

Understanding the type of stringer that suits your design will guide you in making the right cuts and measurements.

Tools Required

To cut stair stringers accurately, you'll need a few essential tools:

Measuring and Marking

Accurate measurements are crucial for cutting stair stringers. Here's a step-by-step guide on how to measure and mark your stringers:

  1. Determine the Total Rise: Measure the height from the lower floor to the upper floor.
  2. Determine the Total Run: Measure the horizontal distance the staircase will cover.
  3. Calculate the Rise and Run per Step: Divide the total rise by the number of steps to find the individual rise. Similarly, divide the total run by the number of steps for the run.
  4. Mark the Stringer: Using the square, mark the rise and run on the stringer board at the appropriate intervals.

Cutting Stair Stringers

Now that you have measured and marked your stringers, it's time to cut them. Follow these steps carefully:

  1. Set Your Saw: Adjust the depth of your circular saw to match the thickness of the wood.
  2. Make Straight Cuts: Align the saw blade with your marked lines, ensuring a straight cut.
  3. Cut the Notches: If using open stringers, use a jigsaw to cut out the notches for each step.
  4. Check for Accuracy: After cutting, lay the stringer against the staircase to ensure it fits correctly.
