Now that the wood is ready it's time to assemble the outer frame of the trunk. I drilled two screw holes at the ends of each long rectangle piece and two holes on the sides of each short pieces and screwed them together (1 1/4" screws) to make a rectangular frame. Do this twice, one for the top of the trunk, and one for the bottom.



After the frames are assembled place your bottom frame on the ground and place your floorboards inside to check the fit (If they fit snugly you know that you measured correctly). Once the floorboards are in place flip your whole bottom piece over (floorboards and frame) and press each board down to the ground (this will ensure your floorboards remain in place for the next step). After doing this, drill two holes and screw (1 1/4") on the two small pieces of wood used to keep the trunk off the ground. Now flip the whole bottom back over and press the floorboards down to where they will permanently be at the bottom of the trunk.



With the three floorboards secured together, it's time to secure them to the bottom frame. Drill three holes along the length of the base, through the frame and into the boards, followed by three screws (1 1/4"). Repeat on the shorter side of the frame. I found that it was easiest to get most of the screw in with a power drill and then finish the job with a hand screwdriver.
