This project was designed for a sustainability class. It's a wooden planter created entirely out of pallet scrap would that would normally just be tossed into the trash. This project can be customized based on what your needs are.
Step 1: Take apart the boards
We started by trying to simply pry off the boards from the center support system. With the rusted nails pretty deep in the wood, we decided just to cut the edges off. We used a hand held circular saw to cut straight through all of the boards on the edges. This way all you have to do is just disassemble the boards from the center support.
Step 2: Cutting boards into uniform lengths
For my basic planter, I used the length of the pallet for the length of the planter. You will need 4 pieces (in all) the same size as the length. You will also need 4 pieces the size of the width. I used 11 inches, but this can be changed if you prefer a wider box.
Step 3: Sanding the boards
This step is optional. I used a sander that works with compressed air, because it was faster. Hand sanding also works. I just did a basic sanding of the front and back, and the edges that would be showing. Sanding is not really necessary, but it's a nice aesthetic touch to make the corners a little smoother and the sides have a little more character.
Step 4: Attach the basic box boards
Before you start this step, put all of the boards in place to make sure they will fit together. A little bit of variation in size is fine, but it's a good idea to make sure they'll stay together without a problem.
Begin by putting a small line of wood glue (Titebond II works really well and it is water/weatherproof) on the ends of the small shelves and attach them inside the long pieces, as shown in the photo. Clamp lightly if desired, while inserting the center dividers.
