I've been wanting to buy or make a sandbox for my son for a couple of years now. Since seeing this on Ana White I knew I had to make it. My son is 4 yo and I didn't think the 4' square sandbox would be big enough for him, so I made it bigger. Ours is 6' square.
2x4 - used leftovers from another project
2@1x8 cut to 71.5 (long sides of the box)
2@1x8 cut to 70.5 (short sides of the box)
did not cut the 1x6 boards (top planks) - actually designed the other boards to fit their length to prevent cutting (saving time) (note that original plan uses 1x4 planks - I used 1x6s so I could use the same number of planks but cover a larger area)
4@2x4 cut to 11.5 (arm rests)
4@2x4 cut to 18.5 (back supports)
followed instructions for assembly otherwise. At my husbands suggestion we put the handles on the sides and can easily open from either side - prevents having to lean over to the middle to open (back saver)
I finished the project in 4 hours including clean up and a couple of small breaks. This is my first Ana White project. It was a lot of fun to build and I hope my son will enjoy it for years to come!
