I'm back, two funerals, a wedding and a long list of honeydoos later. Sad to say that since I am pushing hard to catch up for lost time, the documentation got a little sketchy.

I started on the stab by gluing the plan to a flat piece of mdf, then gluing the jig to that, then setting a pre-cut piece of sheeting. The pencil marks fro the ribs don't show in the pictures. Then I stared laying in the ribs, starting at the root, and working out, using the webs to set the spacing.
