Sandbox

My nephew Nathan loves trucks. Obviously, he needed a sandbox to use his trucks in. So I decided to build him one for Christmas.

My main goal was, of course, to build a functional sandbox that Nathan would enjoy playing in. My secondary goal was to build a bizarre sandbox that would amuse me and confuse his friends' parents.

In researching sandboxes on the internet, I learned exactly three things. One, it's nice to have a place for grownups to sit while the kid is playing in the sand. Two, sandboxes need a cover so they don't get soaked in the rain or used as a litterbox by local cats. Three, sandboxes need drainage for when you inevitably forget to put the cover on before it rains. (My sister, another friend, and I were discussing the sandbox project in the ladies room at an antique show. As we left the bathroom, an unknown woman in one of the stalls yelled desperately after us, "Drainage! Your sandbox needs drainage!!!")

We decided that, based on the space available in our yard and the estimated number of children who would be playing in it, 4' x 7' would be the appropriate size. The design that I came up with was based on the human circulatory system. I'm not sure exactly why I thought this would be a good subject for a two-year-old's sandbox, although Nathan actually does enjoying looking through Grey's Anatomy, which is no doubt why I chose the cover of Grey's Anatomy to work from. As a nod to Nathan's interest in trucks, I made it sort of a cybernetic circulatory system, with wheels in place of the heart and a rather extraneous steering wheel.

Step one was to build a base that would allow for sufficient drainage. I used half inch plywood on a 2x4 frame, with three-sixteenth inch holes drilled in it for drainage at regular intervals.

I built the frame around the base out of 1x12, with profiles cut into it so as to suggest the shape of a man's torso with arms out and fists pressed together. The front of the frame was formed by the forearms and fists meeting in the middle. The sides sloped up to form the upper arms. I put in plexi cutouts in the sides so I could cut away the opening under the upper arms. My hope was that this would emphasize the arm shape and provide a neat little glance into the stria of the sand in the box. The back of the frame was the actual torso, so in addition to the frame, I cut a piece of 1x to suggest a cross-section through the shoulders, which also functions as a seat.

That was all the structure I was planning, but my brother-in-law pointed out that a sandbox designed to be used with trucks really ought to include a ramp. So I came up with one that flipped in and out and cut some curves into the sides so it would look less incongruous. It wasn't perhaps as integrated with the overall design as it might have been, but experience has proved that it was, indeed a worthwhile addition.

After a few coats of clear sealant (I had decided to stick with a natural wood look), I lined the inside of the sandbox with a couple layers of landscape cloth, so I would still have drainage without the sand leaking out the holes I had drilled. I then laid down a layer of that springy stuff that goes under carpets to keep them from sliding around. I thought this would make a nice soft bottom for the sandbox, but I had to remove it after a few months of sandbox use, because it kept collecting sand underneath it, so that the functional sand depth kept dropping.

To complete my torso concept I painted the head onto the canvas that was destined to be the underside of the sandbox cover. Instead of skin, I gave it a woodgrain effect so it would appear more continuous with the wood of the sandbox. Then, using the cover image of my Grey's Anatomy book, I painted in veins and arteries.

Once the paint was dry, I sewed the canvas underside together with the blue vinyl I had bought for the upper side of the cover. With the lid complete, I was able to position it on the back of the sandbox. Where each painted vein or artery on the cover met the back of the sandbox, I drilled a corresponding hole through the seat and screwed in a length of plastic tubing as a continuation of the vein or artery through which sand could be poured.

The last step was adding the wheels - three in the vicinity of the heart, eight little casters indicating the fingers (which have proved to be utterly useless), and an arbitrarily placed steering wheel in the upper right arm.

As of this writing, it has now been 17 months since I made this sandbox and Nathan still plays in it literally every day, so I would say that it has been a very successful present.
