A semi-automatic, hand-operated, pallet building machine is disclosed wherein a gantry assembly is movably mounted to a pallet bed assembly. The gantry assembly is provided with an operator handle, a pair of roller assemblies, and a hinged, spring-retracted nailer carriage which contains a plurality of impact dischargable nail guns. The bed assembly is provided with adjustable slots and jigs for receiving, supporting and aligning the stringer boards and deckboards of a pallet. In operation, pallet stringer boards and top side deckboards are placed and properly positioned on the pallet bed assembly utilizing the adjustable slots and jigs. An operator moves the gantry assembly, using the operator handle, into position over the initial pallet deckboard whereupon the operator, again using the operator handle, causes the spring-retracted carriage of the gantry assembly to move downward until the nail guns come into contact with the deckboard thereby causing each nail gun to discharge one or more nails into the board. The operator then causes the gantry assembly to move to the next deckboard and repeats the securing operation for as many deckboards as are required for the top side of the pallet. Once the top side deckboards are secured, the partially completed pallet is turned over, the bottom side deckboards are then placed in proper position and the securing process is repeated for the bottom deckboards.
