I also modified my fuel tank jig to allow me to put the skins in without a bow in the middle. Part of the next step is to cleco the ribs back into place and I don't want to use the force that my clamping jig requires. So using some examples from other builders I decided it cleco both side of the nose in place and then slowly insert the skin and ribs into the jig. The problem is that I was worried that this would "dent" the skin where the top edges of the jig would be pressing against the skin. See my solution below.
