Just in case anyone else has this - I haven't seen it before on here.
I am assembling the left top skin on the left wing after previously having it together to c/s the rivets over the inboard 4 ribs where the wing walk doubler fits under the skin. When I put it all together and checked the fit of the rivets the c/s holes didn't line up well and the heads protruded, something that did not happen when I made the c/s.
So I put a couple in loose, and took off all the clecos where the doubler was. Then after putting in a row of loose rivets and seeing them more flush, I clecoed along that line. Repeated toward the inboard-most rib and now they are all as they should be.
So word to the wise - fit the doubler well prior to starting to rivet.
Also, the plans say to leave the c/s flush to 5 mil shallow, not deep. If the heads sit a little proud, why does that not matter? Is it because non-skid goes over the top anyway?
