I had another 'faaarrrrk' moment. Suffice to say that I now own three leading edge skins! It's amazing how one simple miss read of the plans results in a complete balls up. I could have used the skin, but every time I looked out at the top surface of the wing with an extra row of rivets there it would have pissed me off. So I bit the bullet and made another skin. It pays to take the time and do all of the marking out first, as it's not always aparaent if you've got it right. The only good thing to say is that I've got this folding business almost down pat now!
