I used the step drill in my drill press to open the pilot holes for the conduit run up to full size of 3/4 inch. Drilled all holes in ribs for both wings. I also used the step drill to open up the tooling hole in left wing ribs 1 thru 9 to 7/16 inch to accept plastic grommets for the planned AoA line. Deburred all the new holes in the left wing ribs.
I attached a piece of angle iron to the outboard rib on the left wing with 1/4 inch bolts and nuts. Cleco'd in all the ribs and double checked that they were all in the correct position/orientation. I numbered the ribs from root to tip to help in reassembling the skeleton after priming. Cleco'd on the rear spar and put a temporaty jack under center to support the sag of the spar.
