Make sure both the vertical and horizontal millimetre scales are correct if you print it out full size.
The link below the image splits the plan onto 2 A4 pages for easier printing
I cut the outline in the aluminium using a jigsaw, but initially only marked the interior cut out on the metal.
I then clamped 2 pieces of straight metal either side of the crease lines before folding the fins.
The interior metal was then drilled and cut away after folding to avoid distortion.
All the edges and corners need to be well rounded and smooth to avoid cutting the fabric or mountings.
The tracking can be adjusted by gently bending the back of the fins to one side but only a very small adjustment is required.
