To draw the curved lines use a flexible batten (spline) passing by the dots that control the curves. 2 2 Once drawn, cut the plywood following the lines. Plane or sand the cut edges to – – produce a clean finishing. 2 3 Where there are notches, sand its three sides, using for that purpose a sandpaper – – backed by a 4mm plywood straight edge bonded to the sandpaper. 3 How to assemble the hull – 3 1 Draw a 6 mm internal parallel line to each edge of the panels. Make a 1,5mm – – hole at each corner of these lines. In one of the panels that is going to be joined to another, make a hole 15mm apart from the first one and from then on, make holes at each 30mm along the line. On the other panel, after drilling the hole made at the corner, continue making holes at each 30 mm along the line. 3 2 With a nylon thread and a thick needle, sew the bottom panels to the – – intermediate ones, and these to the side panels and transom. 3 3 Once the hull is stitched, turn the dinghy upside, make an epoxy putty adding – – micro sphere as a filler until this becomes the consistency of mayonnaise. You can add aerosil up to the proportion of 20% of the micro sphere, to increase the filler viscosity. Apply this putty to the internal edges of the chines with a round edge spatula with 25
