Another session in the workshop today and I managed to get the bottom outboard skin riveted on. Again nothing complicated here as I think I got the technique nailed. It took a few hours but I got it done. After that I fitted the 8 nutplates to the outboard access hole as well.
And with that the main wing structure is finished! Woohoo!!! It feels fantastic to have reached this epic milestone. I also updated my little drawing to show the ailerons and wing structure complete and the flaps are next on the to do list.
It’s starting to look like a plane!
