Here's how I made this Pallet Kids Desk:
I made the legs by gluing three pallet deck boards together and clamping them tightly until they dried. Next, I ripped them down on a table saw until they were roughly the square size I wanted and planed them down evenly. I planned the deck boards down for the desktop until they were the same thickness and smooth. Then I laid them out and squared them up, securing them with two boards on the bottom side so there would be no screw holes on top. I put one deck board running along the front of the desk to make the desk a little deeper, and because it just gave it a bit of visual interest, so I made sure the one underside board overlapped it a bit and secured it as well.
After I had finished assembling the table top, I installed the legs. I attached them with metal brackets and also to the trim pieces that I added around the outside of the table. I added some 1x1" boards to stabilize the legs to one another so the table wouldn't wobble. Finally, I installed some decorative trim to the front and sealed the table with a polyurethane varnish for durability. This desk is bright and cheery in his room and is functional as well as durable. It gives him enough work space to have books and a computer as well as a notepad and studying supplies. However, it still fits in the small area he had to spare. I'm pleased with how this project came out, and it saved a lot of money compared to buying a desk.
