Decided to simply rivet the upper rivet on the trailing edge. Then drill abother hole on the underside at a edge distance apart from the existing hole. When trying to get a dimple tool in there - not a chance, so a normal head cherrymax had to go in there. Looks really ugly, but is OK from a structural point of view, so that's how it will be. Keep this as a lesson for the rest of the narrow double sided parts.
Since I have made the lead weights of sheet, they have to be boltet on. Originally lead would be meltet around the bolts making it one single solid part. When using the sheets I have to make a plate from harder material so the bolts will not just enter ino the led. I started making them from scrap aluminium.
