Second Wing Build Progress

Posted On August 12, 2019

This past weekend I completed several tasks on the starboard wing. The most time-consuming task was aligning the bottom skins onto the spars – the holes didn’t line up very well, and I had trouble getting the inner skin to lay flat on my first 2 attempts. Here’s what I accomplished over 15 hours:

Completed riveting the ribs to the spars
Align the bottom wing skins. I had to pick an alignment such that most of them fit; this took a few tries. That meant the next task was…
File and/or ream holes to get rivets to fit into the holes, deburring and cleaning up metal shavings as I go
Rivet the bottom skins in place
Paint the landing light bracket pieces white
Prime the leading edge skin – and also paint the small section that surrounds the landing lights
Attach leading edge skin
Flip wing over
Run cable assembly for the wingtip lights
Make wiring harness for the landing lights: twist the three conductors together and then put into a braided wire jacket

As I was trying to find the best fit for the skin, I had to trim the skin a little here because it was pushing up against the bracket for the flap, causing the skin to wrinkle

Setting up many, many clecos and rivets after the third alignment attempt

This is the kind of misalignment I had to work with on the main spar cap. I can’t get a rivet into this hole without elongating it.

After flipping the wing over, I started working on the electrical
