Bottom Wing Skin – Part 3

With both wing skins match drilled, I begin to prep the skins for priming. First I remove enough clecos so I can remove the blue film on the skin where the skins overlap. This will allow me to mark and mask off the skin to prep them to sand.

I wasn’t very aggressive on the top skins, however I’m interesting in trying to make this overlap section a little nicer on the bottom. Granted nobody but me will really be looking at the bottom of my wings, but I guess it’s just a challenge for me.

With the film removed and the overlap marked in sharpie, I then remove both skins and coil up the larger skin to get it out of my way. I then can begin to file and deburr the smaller skin just in case I have enough time to prime it before my fuselage arrives.

Bottom Wing Skins – Part 1

With the weather and my schedule continuing to prevent me from getting any parts primed, I continue to move forward with other items on my build. I had no intention of attaching my bottom wing skins until just before I was ready to attach the wings to the fuselage, however there is no reason why I can’t get the skins prepped.

Starting off I locate the J-stiffeners that I pre-drilled last year and the bottom wing skins. As I attempt to install the wing skins, I noticed that the skins needed to be filed a bit to fit around the hinge brackets. Just a little filing and the skins fit easily over the brackets.

I then start to cleco everything together and had a moment of panic when I saw that my J-stiffeners were not drilled in a few locations. Took me a few moments to realize that this was correct based on where the access panels are. (They were match drilled based on the spars). I final-drilled and match drilled all the holes on the left wing.

I also started to get some wires for both my pitot and wingtip lights. I started to pull them through my access holes and so far am leaving my conduit empty for future use. Also am using my label maker to print heat-shrink labels for every wire.

Still to do: Mount the Pitot tube mast and Pitot controller box. Currently I am planning to mount in the same place indicated int he plans by vans. Just trying to figure out if I need to twist / run a ground wire back to the wing root or ground the pitot locally.

Outer Leading Edge – Part 9

With my parents visiting for a few days, I had my father help me out a little. Got the right wing moved out of the cradle and clamped to my workbench and the leading edge clecoed onto the spar. Then got my dad to help me rivet on the leading edge.

As I was getting the rivets set, I identified a few rivets that I wanted to replace for one reason or another. I’m sure the rivets were ok, but it’s easy to replace in it’s current state. Also going back a few days or with a fresh set of eyes is always a good idea.

I finish up and replace the handful of rivets on the top skin, and rivet the leading edge ribs to the spar. We then shuffle the wing back into the cradle. This gets me in a much better place from a space perspective now that I shouldn’t need to remove the wings from the cradle until I get to the airport.

Outer Leading Edge – Part 8

Circling back to finish the landing light lens. With the experience on the other lens, I’m ended up cutting this lens to the “proper” dimensions this time. (The directions are correct even if you don’t think they are. Go figure!) Still debating if I will purchase a replacement lens for the right wing or not as the other does work just fine.

With the lens cut and fitted, I go ahead and mount the landing light in the wing (off camera) and struggle to figure out how to actually screw in the landing light lens as I can’t get behind it to apply any pressure. The lightbulb moment was when I realized I needed to use tape on the lens to help provide the outward pressure so I can screw in the lens.

With the lens installed (and protected by additional tape), I then got some assistance from my wife to cleco the leading edge to the wing spar. Getting the ribs clecoed into place I then begin riveting the leading edge to the spar. As a small note on the blind rivets, not sure if it’s just my blind rivet squeezer, but I really don’t like setting blind rivets.

With all the ribs riveted to the spar, I squeeze the skin rivets then ask my wife for assistance to rivet the top of the leading edge. Easy enough and once done I get to stand back and admire my progress. Plan on getting the other wing done shortly as I approach my fuselage crate date.
