Step 14: Glueing of the leading edges
1. Cut two pieces of Dacron, 50mm wide and a length of 1500mm.
2. Fold the Dacron double over the full length. The easiest method is to take the Dacron together between your fingers over a distance of about 10cm and rub that segment across the hard side of the hardboard, then the next segment of 10 cm and so on (look at step 10 for some pictures).
3. On one end you mark 60 mm from the end. Here we will make a fortification for the tensioning of the leading edge. Fold over the 60mm part and glue tight.
Watch Out: put a weight on this glued part, or the stiffness of the Dacron will tear the glue apart and make it let go unfold.

4. Tape the leading edge from the right sail aligned with the bottom border, tape the upper side. The fortification is at the bottom part.
5. Put the sail down with the front side up and glue the sail onto the leading edge, starting from the bottom. This is a difficult job, use papertape to help holding everything according to the bend in the leading edge.
6. At the transverse lines on the plan you must make two cuts. This is where we will place the APA connector. We use this method to prevent our flying lines to get stuck behind the connectors.
Watch Out: The cuts in the right sail start at the fold and are 17 mm long. The rest is 8mm from the top of the leading edge. Do this step for the upper and the lower spreader.

7. Glue the front side of the leading edge. Put glue only at the inner side, allowing free space in the leading edge to get the spars in.

|
8. Cut the top of the leading edge according to the shape of the left sail.

|
9. Tape the leading edge for the left sail alligned with the bottom border, tape the upper side. The fortification is at the bottom part.

10. Before glueing the sail onto the leading edge, the cuts for the connectors have to be made.
Watch Out: The cuts for the connectors of the left sail start UNDER the fold and end at 8 mm from the bottom side of the leading edge.
