I had some time to get back on the project, so I started by beginning some of the preparation of the ribs that will go in the Horizontal Stabilizer. The edges of all of these parts are still sharp from the factory punching process, so I used the Scotch-Brite wheel on the bench grinder to smooth the outer flat edges. All interior lightening holes were deburred with the hand deburring tool and then smoothed over with a Scotch-Brite pad. Then I used the bench grinder again to contour the leading edge facets of the nose ribs to prevent protrusions through the skin later.
What's next? Dry fitting, match driling of these ribs, and probably some priming.
