DANNYMAC,than one rib jig. I made ribs and false ribs for a Bi-plane from twodifferent jigs made from two factory supplied prints. When half waydone with ribs , by matching the false to the main ribs, found they werequite different. Enough so that when put on a smooth wing, they wouldhave looked like crap. I had to remake the false ribs on the main ribjig. My advice is to lay the two ribs side by side and make sure theymatch exactly. I knew a guy, who has built more than one plane, whose almostcompleted Baby Ace wing was damaged by a hanger roof collapse. He saidthat since he had discarded the rib jig, he couldn't make another one torebuild one wing , and have the plane fly right. So he wound up givingthe project to the local EAA. I'm no expert, only passing along what I've seen along the way.waltDANNYMAC, By reading some of yourlast notes,it seems that you are using more than one rib jig.
