Recently I was in the market for a new desk.
I wanted to make a desk that was able to be disassembled and packed flat, made from few and easily obtainable supplies with simple tools.
The desk can be created from the following supplies:
1 4'x8'x3/4" A-1 plywood sheet
2 4' 3/8" steel rod
2 3/8" nuts
2 3/8" wingnuts
You will need the following tools:
Circular saw (or other saw for making large cuts in the plywood)
Coping saw (for cutting the notches)
I also recommend a squaring device such as a speed square.
Step 1: Create the tops and the sides
Divide the plywood into 4 pieces measuring 2'x4'. You could have the lumber yard do this for you, or use your own tools.
Two of these will be for the top and bottom of the desk and two will be for the sides. I recommend using the smoothest and most regular surface for the top of the desk.
Step 2: Cut notches into the sides of the top and bottom pieces
There needs to be a notch in the top and bottom of the sandwich you will build. Measure out a notch that is 6 inches from the front and the back of the desk and 1 1/2" deep. Use your coping saw to cut this. Repeat until both the top and the bottom of the sandwich have the notches cut on both sides. You will have cut four notches when this is complete.
Step 3: Cut the tabs in the legs
Measure and cut out two of the corners of each leg. Since I'm using 3" high boards for the sandwich and the top and bottom of the sandwich are 3/4" thick I need the depth to be at least 4 1/2". I wanted to be sure things fit snugly and didn't mind the overhang so I made mine 5 1/2" deep. The width of each cut should be 6". This makes the tab match up with the notch you cut in step 2.
