More Riveting On Forward Fuse
This morning I went to the EAA 690 pancake breakfast...it was actually really crappy weather, but about 5 or 6 RV's showed up. It's really motivating to see all those RVs out there. Anyway, when I got home I started setting nutplates in everything...including the seat ribs (I'm going to have removeable seats). When I got tired of doing that (waaaay too many nutplates doing the floors this way) I started looking at what else I could do. I decided that I could do some of the riveting on the forward fuse by myself with the floor off...so that's what I did. I riveted the forward half of the 704 and the stiffeners.
I also decided to go ahead and rivet the two inner floor stiffeners at each end. Yes, the one on the left here has holes that are off-center. The reason? Well, this is the way the stiffener lined up. You can see in the back where it butts against the gray part....and what you really can't see is on the closest end it butts against the big honkin' brackets where two of the engine bolts go. Well...the left stiffener lined up a little off-center of the floors holes. I have no idea why. The edge-distance is good...so that's all that matters. I mentioned this earlier when I was drilling all this stuff out orginally.
Next I started riveting the aux longerons. No big deal here. There aren't that many AN426AD4 rivets on the outside of this airplane...but here's one place.
And here you can see where I riveted the skin-to-auxlongeron-to-weldment-to-F-684 gusset rivets. I've only riveted the right gusset on this fuselage is already getting STIFF. More tomorrow (hopefully).
