Made jig for building wings from two metal work benches 2000mm x 640mm x 900mm and 5 ply Marine board. I used 10mm set screws with nuts for height adjustment; levelling sideways and lengthways. I used 1800mm x 600mm x 19mm and 1800mm x 600mm x 9mm 5 ply to lift the 2400mm x 1200mm x 12mm and 1150mm x 1200mm x 12mm interior blonde marine ply above the bench ends to ensure that the jig board was clear of obstacticals and flat. I used a 4530mm x 75mm x 12mm Tasmanian Oak along one edge as a horizomtall straight edge.
