Step 1: The Room.
I decided to affix the desk to the side of my IKEA bookshelf. its heavy, thick and wide enough to attach a decent sised desk to.
Step 2: The Materials
I settled on a piece of 30cm by 75cm plywood for the actual desk and a 8cm wide piece of pine for the hinge brace.
Step 3: Making the Hinge Brace.
The pine blocks were sanded smooth before being attached, wood glue was used to strengthen the bond.
Step 4: Staining and Varnishing.
The desk was then given three layers of a tough polyurethane varnish. As with the wood stain, the desk was given two initial layers with a light sanding, followed by a final light layer.
Step 5: Mounting.
I used two brass door hinges, affixed with 6 steel screws each. I used a 1m long 3cm link chain to hold the desk upright.
The chain is hooked onto a small brass hook that is screwed onto the edge of the desk whilst the other end is held in place at
the top of the bookcase.
