Install Nailers/Blocking for Decking

What happens here

When building a picture-frame deck, it's crucial to install 'nailers' or blocking within the deck frame to support the ends of the interior decking boards where they meet the perimeter. This prevents the boards from 'floating' or feeling squishy, ensuring a solid and stable surface. These nailers are typically cut from scrap wood (e.g., 2x8s ripped down) to fit snugly between the existing joists, providing a solid anchor point for the decking screws. Ensure all nailers are installed correctly before laying the main field of decking.

Goal: Provide solid support for the ends of interior decking boards.
