Cut four pieces of 2-by-4 75 inches long with a circular saw. Cut four pieces of 2-by-4 39 inches long, using a circular saw. Cut 10 pieces of 2-by-4 10 inches long. Cut two sheets of 1-inch thick hardwood 75 inches long and 18 inches wide. Cut two sheets of 1-inch thick hardwood 39 inches long and 24 inches wide. Cut 23 pieces of 1-inch thick hardwood 37 inches long and 2 inches wide.
Fit the 1-inch pilot bearing into the router. Cut a groove 1-inch deep and 1-inch wide into one edge on one of the 2-inch wide faces of a 75-inch piece. Cut a second 1-inch wide, 1-inch deep groove in a second 75-inch piece in the same way.
Measure and draw a 1-by-1-inch square on each end of the 2-inch wide faces of the 75-inch and 39-inch long pieces of a 2-by-4 with a pencil and ruler. Cut these squares out of the 2-by-4 pieces with a hacksaw. Fit the cut pieces together by interlocking the cut ends, to form two rectangles 39 inches wide and 75 inches long. The grooved pieces must face one another.
Glue the interlocking joints together with wood glue. Reinforce the joints with a hammer drill and screwdriver drill bit to countersink long screws into the joints. Glue and screw 10-inch long pieces to the corners of the non-grooved rectangle so the 10-inch pieces stand vertically. Glue and screw the other rectangle on top of the 10-inch pieces, to form the bed frame.
Glue and screw one 10-inch piece in the middle of the 39-by-18-inch sides of the bed frame. Glue and screw two 10-inch pieces side-by-side in the middle of the 75-by-18-inch sides of the bed frame. These are the side support pieces for the bed.
Cut two pieces of 2-by-4 to 71 inches long. Cut four pieces of 2-by-4 to 16 inches long. Glue and screw the 71-inch pieces into the bottom of the bed frame 20 inches from the inner edge of the 75-inch-long sides. Glue and screw the 16-inch pieces into the bottom of the bed frame between the 71- and 75-inch-long pieces, 16 inches from the 39-inch-long ends of the frame.
On the 75-inch-long hardwood pieces, measure 2 inches along the bottom 75-inch side, then 4 inches up. Draw a rectangle 10 inches tall and 31 1/2 inches wide. Measure across 8 inches and draw another 10-by-31 1/2-inch rectangle.
Fit the 1-inch drill bit into the drill. Drill starting holes in the corners of the rectangles you just drew. Cut the rectangles out of both 75-inch-long hardwood sheets, using a hacksaw. Screw the 75-inch hardwood sheets onto the sides of the bed. Screw the 39-inch-wide pieces to the ends of the bed. Screw the 37-inch-long pieces into the grooves, with 1-inch gaps between them.
Cut one piece of 1-inch thick hardwood 31 1/2 inches long and 20 inches wide, using a circular saw. Cut two pieces of 1-inch thick hardwood 20 inches long and 9 inches wide. Cut one piece of 1-inch thick hardwood 29 1/2 inches long and 9 inches wide. Cut one piece of 1-inch thick hardwood 33 inches long and 11 inches wide.
Glue and screw the 20-by-9-inch pieces to either end of the 29 1/2-by-9-inch-wide piece, to form a “U” shape. Glue and screw the 31 1/2-by-20-inch piece to one of the large open faces of the “U” shape to form a drawer with no front panel on it.
Screw a drawer handle to the center of one side of the 33-by-11-inch piece. Turn this piece over. Glue and screw the drawer to the 33-by-11-inch piece so there is at least a 1/2-inch lip all around the drawer and the handle is on the outside of the drawer. Repeat this process to build the other three drawers.
