How it's built
The 6 top deckboards (3/4 in thick) are nailed through 3 stringerboards into 9 blocks, 5-1/2 in × 5-1/2 in × 3-1/2 in.
The base is a perimeter frame: bottom boards on all four sides, 3/4 in thick. The openings between the blocks take forklift tines from all four sides (full 4-way entry). Pallet-jack wheels need an opening in the base, so a perimeter base takes jacks from the ends only.
Nails follow the Uniform Standard for Wood Pallets minimum per joint by board width: 42 in the top deck and 27 in the bottom deck, 69 in total, 2-1/4 in helical.
