Installed aluminum tubing for pitot tube. Surprisingly it took longer than originally expected. Pushing 1/4" diameter tubing through many 1/4" holes results in a bit of friction and a bit of a battle. Each rib has two holes to feed the tubing through; the rib itself and the doubler on the other side of the rib stringers. So ultimately there are about a dozen holes for each section of tubing. Cleaned up a few misc areas.
