This is the arrangement of the modules for Queens Wharf. The cross beams are dimensional pine (4X1) and the side beams are 25mmX25mm aluminium angle. I made two modules for this layout, each 1.5m long (5′) X 600mm (2′)and they are aligned using pattern makers dowels. You can see these as small black dots on the end beams. A friend cut all the circular holes to make the structure as light as possible and to allow wire runs. This was an awful job and I was glad not to have to do it 🙂 The wood and aluminium are connected with construction adhesive and wood screws.
