Actually I thought it would take at least two more sessions, but during riveting, we kind of got the hang of it and increased speed. However bending over the wing and trying to apply pressure to the bucking bar with stretched arm is hard.

Also the outboard skin is longer (wider) and has only one access hole. So e need to “bend” the skin more than the inboard skin.

However you have to be careful not to overstretch the skin and really dent the skin deforming it beyond repair.

You can reach the rear spar side via the forward side lifting the forward side of the skin. The main spar side can be reach via the holes in the ribs, lifting the side of the skin.

The last few rivets and the right wing is closed. Note the tape on the inboard rivet holes. These should not be riveted now, but are probably used for attaching the fairing that joins the wing and the fuselage.

Time: 4 Hours, Rivets: 293/5

So we start with that, meanwhile my Dad worked on the piano-hinge of the Flaps, trimming them to the right size.

With the Flap brace countersunk and spit-primed, we started to see how to rivet the bottom skin to the wing. The plans are “clear” work in “L” shape, but it’s not clear which side the “L” should be.

At least I don’t want to bend (over-stress) the skin. First step is riveting the skin to the rear spar across the wing-walk ribs.

Checking the rivets is hard, because there is not much to see. With the flashlight I can check several of them. The rest is feeling if they are consistent.

I had to drill out five of them an reset them properly. The access holes in the bottom skin are really convenient, which makes me wonder how to do this on the outboard skin, which only has one hole and is much wider.

I have to concentrate on the inboard skin for now, because I’m clueless how to do the outboard skin. This one is already hard and it’s the easy one. Now reaching the rear spar through the access hole is hard, but I can just reach it.

Time: 5 Hours, Rivets:  207/5
