The Base

• 1). Turn 2 of the 48 inch boards on the 2 inch side. The using them, as the sides of your base, attach one of the 36 inch boards, also on it's 2 inch side, to the front of your box.
  
  
• 2). Screw it in from the front.
  
  
• 3). Take another 36 inch board and screw it to the back. This will form a rectangle 48 inches long and 36 inches deep. This is the base.
  
  

The First Step

• 1). Place 2 of the 36 inch boards flat (the 8 inch side down) across the very front of your base. Allow a slight overhang of about a half an inch or so, at the front.
  
  
• 2). Screw the first board down in several equally spaced places across the front.
  
  
• 3). Place the second board flush against the first.
  
  
• 4). Screw the sides of both boards down, make sure you are screwing them into the base.
  
  
• 5). Take another 36 inch board and stand it on edge (the 2 inch side down), place it flush against the back of the second board.
  
  
• 6). Screw it in place, where the two boards meet. This will be the front board of the next step.
  
  

The Second Step

• 1). Attach one of the 36 inch boards to the left side of the upright board you placed in the previous step.
  
  
• 2). Attach another of the 36 inch boards to the right side. Screwing each one in from the front.
  
  
• 3). Screw one of the 36 inch boards to the back of the two from above. You should now have a box that is 36 x 36. This is the base of the second step.
  
  
• 4). Place one 36 inch board across the very front of this new box, and screw it down at several places across the front. Be sure to leave about a 1/2 inch overhang on the front.
  
  
• 5). Place another 36 inch board flush against the first one, and screw both down along the sides.
  
  

The Third Step

• 1). Place a 36 inch board, 2 inch side down, flush against the second board. Attach it at the bottom where the two boards meet.This is the front of the base for the third step.
  
  
• 2). Attach a 16 inch board to the left side of the board you placed in the step above.
  
  
• 3). Attach the other 16 inch board to the right.
  
  
• 4). Screw them both in, front to back.
  
  
• 5). Attach a 36 inch board to the back of the 16 inch boards. This forms the base of the third and final step.
  
  

The Lid

• 1). Place the last two 36 inch boards beside one another. Do this when they are not on the base.
  
  
• 2). Measure 3 inches in from the left side, and draw a line across both boards
  
  
• 3). Measure 3 inches in from the right side and draw another line, also across both boards.
  
  
• 4). Attach one of the 1x2's, two inches from the top of the first board, along the line you drew.
  
  
• 5). Screw it down in several places on both boards.
  
  
• 6). Attach the last 1x2 in the same manner as the first, along the other line. Be sure both 1x2's are 2 inches from the top. This is the only thing holding the top step together.
  
  
• 7). Attach the hinges to the bottom edge of the step.
  
  
• 8). Attach the step assembly to the base at the hinges. Make sure the lid hinges outward at the back of the step.
