Abstract: A base-supported rotatable frame assembly that defines four upwardly and inwardly extending side frames. A pressurized fluid-actuated mechanism intermittently rotates the frame assembly through first, second, third and fourth stations. Stringers are removably placed in fixed positions on a side frame when it is at the first station, and deck boards are placed in abutting contact with the stringers when the stringer-supporting side frame is at the second station. The deck boards and stringers are nailed together at the third station to provide a single face pallet, which pallet is removed when the supporting side frame moves to the fourth station. A second of the inventions may be used to transform the single face pallet to a double face pallet if desired.
