Up early this morning again before work. I scuffed the flanges on all the main ribs as it is much easier to do this before fluting. Also worked out a jig to drill out the holes in all the main ribs for the wiring conduit per the Vans FAQ recommendation. More on this next session.

The crossed lines denotes where the 3/4" hole will be drilled. Note the drill jig is cleco'd on.
