The ribs used in the wing come already cut and formed, and with small holes for the rivets in the flanges and large holes in the main surface (the"web") drilled to lighten them. So assembly should just be as simple as lining them up with the spar, and riveting away. Well, not exactly...
First, the ribs have to be "prepped". This consists of hitting the edges with a Scotch Brite wheel to round off any burrs from the cut edges, then bending the edges to a perfect 90 degrees with a hand seamer, then
rounding off the interior edges with a Dremel, then drilling holes for the wiring to pass through, then using a Scotch brite pad by hand to scuff all of the surfaces, then dimpling the rivet holes, then fluting the flanges to straighten the rib, then degreasing and cleaning the ribs, drying them and finally, priming then with a self etching metal primer. And there are over fifty of them. So the past few days, in my builder's log, it just keeps saying "prepped ribs". That's why.
