Put a piece of news paper down on your work surface to protect the top. With the rounded edge facing down, position the assemble table apron unit in the center of the top. Measure 2 inches from the edge of the apron edge and position the hinge. Take a pencil and mark the holes where the holes need to be for the screws. Put a piece of tape ½ inch from the end of the 1/8 drill bit and drill the holes. Be careful not to drill all the way thru the wood.
Position the hinges and attach with the STEEL screws.
