Materials: 3 Ikea Lack side tables 55x55cm; 1 Perfekt plinth; 2 lazy susan bearings; one pot of strong contact adhesive.
Step 1: Cut the plinth into 4 equal lengths and attach together to form a square base. Cut a piece of mdf to size and nail onto the top.
Step 2: Glue one of the Lack table tops to the mdf.
Step 3: Cut the Lack table legs and glue together to form a square. This part will be used to raise up the uppermost table top.
Step 4: Use glue to sandwich the lasy susan bearings between two matching pieces of mdf. Glue one side to the riser and glue the whole thing to the table-top. Glue the other lazy susan sandwich in place.
Step 5: Cut some table legs and fill with concrete to act as counter-weights to overhanging parts of the rotating table tops. These are inserted into the rotating table tops in the corner where the table is attached to the lazy susan bearing.
Step 6: Glue the remaining two table tops to the lazy susan bearings (you may need to weigh them down until the gule sets).
