Section: 14
Hours: 5

I'm back to working on the wings. Today I worked on finishing the edges of the 28 wing ribs. I ran all the edges over the grinding wheel and used the die grinder to deburr all the interior cutouts. Then I final sized all the flange rivet holes using a #40 reamer in the air drill. The reamer leaves very clean holes, but I still did a de-burr pass after reaming. Each rib has 44 holes so that was 1,232 reams and 2464 de-burrs (one for each side of the hole). Lots of work with little to show other than a big stack of ribs!
