2.7 hrs
Now that the wing is really taking shape, it's hard to stop. There's a strong urge to push on through to completion. In reality, completion is a long way off. Need to pace myself better.

Finished deburring all of the leading edge ribs. Used the scotchbrite wheel for the crevices. The wheel has deep grooves which are great for deburring the flanges. That's after a light filing and then medium sandpaper. The grooves are so deep that it was easy to trim it so that one narrow piece of wheel is left. This fits great in the rib notches and makes deburring relatively quick and easy. Still takes an hour to do all 14 of those ribs. Check with the fingers for any rough edges, clean up as required. Viola! Done!

Then fluted all leading edge ribs. The inboard 908 ribs are thicker and much more difficult to flute. Took about an hour to do that.

Finally it was time to get the leading edge skin and put it in the cradle. Tried leaving the inside skin on for a trial fit of one rib, but decided that was asking for trouble.

Peeled the plastic fom inside of left skin. Then clecoed all of the 909 ribs to top side of leading edge skin. Looks like the next step is going to be very difficult.
