You guys are a little ahead of me......
I got to this step tonight and have the same issue, but would like clarification please.
Q#1:
As indicated on p.11-03 step 2, we are to countersink the top seven holes as indicated in figure #2, labeled "countersink", so these holes get sized for the Ad3 rivets, not the deeper hole for the skin dimples -- or that's what I understand it to mean.
Per the thread, the bottom seven also get countersunk, and I am assuming sized for the ad3 rivets and not the skin dimples?
Q#2:
Referring to p.11-04 these 14 holes, 7 top and 7 bottom are not marked, indicating they are skin and or rib attach holes thus indicating they be countersunk to the deeper depth for skin dimples. I've already counter sunk the top 7 to the rivet depth, but as these two drawings appear to be in conflict, I wanted another opinion before working on the bottom 7. I am guessing these (all 14)are used for just the rib attach points and not skins, so I am guessing they be drilled to the rivet depth, thus figure 2 on p. 11-03 is incomplete and p.11-04 indicates in error these holes be drilled to the deeper depth?
Q#3:
Again p.11-04, all holes not otherwise indicated, get countersunk to skin dimple depth (flanges only)?
