1. 0:00–0:03 Cut Stringers From How to Lay Out and Cut Deck Stair Stringers, Step 2: Select Stringer Material

   Begin by acquiring appropriate structural lumber, typically 2x12s, for the stair stringers. Accurately measure and lay out the rise and run of each step directly onto the lumber. Using a carpenter's square, mark the cut lines precisely. Carefully cut the stringers using a circular saw for long, straight cuts and a jigsaw for the inside corners, ensuring "no overcuts allowed" to maintain structural integrity and a clean finish. This precision is crucial for the stability and aesthetics of the final staircase.

   Cut the treads (the horizontal walking surface) and risers (the vertical panels) to the exact dimensions required for each step. Precision is key to a snug fit. Apply construction adhesive, commonly referred to as 'glue,' to the top of the stringers and the back of the riser where it meets the stringer. This adhesive helps prevent squeaks and adds significant structural strength. Then, carefully install each riser, followed by its corresponding tread. Secure both with appropriate fasteners, such as finish nails or screws, ensuring they are flush and level.
