Frustrating night in the shop. I'm at the stage of assembling my Horiz Stab. I got the spars assembled no problem, as these were all squeezed rivets. The task for tonight was to try to rivet the nose ribs into the HS skin. The problems:
1) The first problem was that my clecoes won't hold. I guess from match-drilling and deburring the holes in the skin and ribs, the holes are big enough now that the spring-back force of the rib near the nose is too much for the clecoes to hold... they just go shooting out. Anyone else have this problem?
2) I managed to get it clecoed enough to start trying to rivet the middle nose-rib in place. I had a real hard time getting a feel for this, and ended up botching a couple of rivets. When drilling these out, the holes have gotten enlarged a bit. I don't know if this means I need a new skin and rib, or what. What is the usual way of dealing with this?
3) Also, I'm not sure about the rivets that I "successfully" set... they don't seem perfectly flat and smooth agains the skin... with the edge of my fingernail I am able to "pick at" the edge of the rivet head... is this normal, or should they be smooth as a baby's bottom?
Thanks for any help!
