What happens in this clip
Before permanently installing the treads, dry-fit them into place. Gently slide each tread under the previously installed riser. Check that the tread fits snugly against the skirt board on both sides and that it is tight against the riser. A good fit means minimal gaps on the sides and a flush connection with the riser. If a tread is too tight, it may need slight sanding or trimming. If it's too loose, you might need to adjust or recut. After confirming a good dry fit, carefully remove the treads, ensuring not to damage the risers.
Goal: Verify the precise fit of each cut tread before permanent installation.

About the full video
This video provides a detailed guide on installing wooden stair risers and treads using a unique interlocking joint technique. It covers the preparation of materials, precise measurement and cutting methods for both risers and treads, and their final installation, emphasizing accuracy and the use of specialized tools for a seamless and sturdy finish.
Step 5 of 8: Test Fit New Treads
Before permanently fastening, place each newly cut and sanded tread onto its intended stair. Ensure it sits flush against the riser and any adjacent walls or stringers. Check for any gaps or overhangs. Minor adjustments can be made by carefully trimming edges with a sander or a fine-toothed saw. This step prevents costly mistakes and ensures a professional finish.
