Brief Description: Wings on, second and last time
|
|
I was at the hanger every day from 12/26 through 12/30--I'm guesstimating a net 40-hr work building an airplane while off work from Xmas to New Year's.
12/26--see note to the 12/25/2017 entry.
12/27--Prepared to plug the wings in the final time.Spliced the Dynon C-to-V converter boards to the ends of the pigtails in place at the wing roots. There's room, I think, to route the wires over the spar (and under the wing root fairing) to the BNC connector on the inboard end of the fuel tank. I'll put down a ~1x1" layer of self-fusing silicone tape on top of the spar, lay the3-wires on it, then cover with a second layer of tape. The wing root fairing should compress any parts of the sandwich proud of the wing skin. Also installed push-in elbow fixtures to the pitot and AOI 1/4" Al tubes at the left wing root. Short lengths of plastic 1/4" tubing will curl ccw around the aileron pushrod opening, entering the fuse below and out of the way of the pushrod, where two more push-on elbow fittings will connect to the internal pitot and AOI lines. An unused spark plug wire hold-down was installed on the root rib to secure the short tubing between the pairs of elbows.
Karl, his friend Ian and Ian's S.O. Kendra came out to help plug in the wings. Pushed the wing cradle close to the left side and pulled the nav/strobe cable through. (Wingtips were taken off 12/26.) Kendra and Ian took the root leading and trailing edge, Karl took the tip. They lifted the wing off the cradle, rotated it, LPS-lubed the spar stub, and it went in pretty smoothly except for forgetting to pull on the nav/strobe cable to take up the slack. Fortunately, cable was NOT sliced by the lower wing. Drive in and upper and lower 7/16" drift pin to temporarily secure the left wing, Did the same with the right wing (and remembered to take up the slack of the nav/strobe cable and autopilot wires). Kendra helped put in the rear spar bolts so I could step on the wing walk to get out and in to the cockpit.
