I had previously marked the spot for the pitot-static tube assembly. Center-punched it, pilot drilled, then up-drilled to 3/4" using a hole saw. Measured corner distances on the assembly and pilot drilled to #40 for the mounting rivets. Held in position and drilled the first hole. Cleco'd. Gently ensured pitot was square with the airstream and drilled/cleco'd a 2nd hole. Drilled the remaining 2 holes. Updrilled all 4 to #30, final size for A4 rivets. Deburred all.
Re-assembled wing nose skin after re-assuring that the wing was level with no twist.
Ran 3-conductor wire from the wingtop light position down the length of the rear spar. Determined where I wanted the pitot-static lines to exit the wing box, since there were no holes in the main spar in the bay housing the assembly. Drilled two 7/16" holes for the grommets protecting the pitot-static tubes.
Drilled-out some rear spar rivets in order to install the zip-tie holders for the tubes & wires. Installed 14 of them. Used zip-ties to secure the pitot static tubes, wingtip light wire, and fuel sender wire.
Installed wing trailing edges and cleco'd the bottom edge.
