Lay the 2-by-4-inch plank on a large flat surface. Arrange the garden tools so their handles or widened ends cross the plank where they can hang from installed hooks or prongs. Use a marking pen to draw a dot on each side of each tool. Mark the dots about 1/4 inch from the lateral margins of the tools so that the hooks or prongs, when installed, support the tools and allow for easy removal. Remove the tools one at a time. As you remove each tool, write the name of the tool on the plank above the corresponding marks.
Use a drill and drilling bit to bore pilot holes, about 3/4 inch deep, at each mark. The drilling bit must be slightly smaller in diameter than the threaded shanks of the hooks or prongs.
Screw a hook or prong into each pilot hole. Turn the hooks or prongs until the threaded shanks are no longer visible. If necessary, use pliers to increase torque for easier turning.
