How Skateboard Decks are made.
Four holes are drilled in either end for the truck mounts.
At this stage the board is still square so next it is cut to shape. The edges are sanded round and the board is sealed with a clear coat of finish. Finally the graphic on the bottom is applied usually by screen printing. The deck is dried and is now ready for shipping
