I started to assemble the Left Leading Edge. What a bitch. The skin was placed into the jig and the ribs have to be fitted into the skin. The instructions say it would be easier this way but I'm not so sure. It was easy enough to cleco the ribs to the bottomside of the skin but near impossible to stretch the heavy gauge skin enough to insert the clecos into the topside skin. I struggled for about two hours with no joy. I quit for the day totally frustrated. I know I need to think this out and come up with a viable solution.
