I started riveting today. I got the skeleton riveted together and back-riveted then stiffeners to the skins.
- Skeleton riveted together.
- Skins back-riveted. Nice, huh?
I’ll try to finish up tonight, but I need to figure out a way to dimple the ribs near the trailing edges. I should probably follow the directions and fabricate the special dimpling tool described in the plans. Off to the hardware store for some steel…

okay, again with the newb questions- how did you hold the stiffner in place while you backriveted? the clecos stick through, so that idea is out, right? what did you do?
With the rivets sticking up from the other side (taped in place from the outside), the stiffener isn’t going to go anywhere laterally. With a special sliding sleeve backrivet set, the pressure from the sliding sleeve keeps the stiffener snug against the skin as you set.
I ended up using a regular flat (sometimes cupped) set, and to keep the set on the rivet, I used my thumb and forefinger of the other hand to steady the set and to apply a little pressure on the stiffener to keep it snug against the skin.
I have some better pictures of backriveting last night and tonight in my latest two posts.https://n999za.wordpress.com/2010/02/26/more-stiffeners-some-skeleton/
i got it figured out, just need to get that trailing edge done
