I was able to get a few more hours invested into the plane. Most of that time was actually taken up clecoing the tail cone together, lining everything up for riveting.
You’ll notice that the clecos are all inserted from the inside out. This was done because I’m going to attempt to back rivet as many of the rivets in the tail cone as I can. Having the body of the cleco on the inside leaves only a little nub of the cleco that points outward. This will keep the clecos from getting in the way of the back rivet plate.
Speaking of the back rivet plate, in order for it to work, the skin needs to sit completely flush against the plate. So I had to get a system up so the little nubs wouldn’t interfere. To do this, I embedded the plate into a piece of carpeting. My plate isn’t as thick as the carpet, so I also had to shim the plate up with a few pieces of scrap masonite. It’s been working well so far.
With everything cleco’d and the back rivet plate set up, I began by getting the stiffeners on the bottom skin riveted.
And that’s all I had time for. Hopefully I’ll get the rest of the stiffeners riveted tomorrow.
