Before I broke the whole wing down I CSK'd the #8 screw holes on the in-board edge. To facilate this I fab'd up a little drill guide. The purpose of this guide was to help center the CSK pilot inorder to keep the CSK concentric on the hole. The problem was the hole was #19, the pilot #30 so it wants to wonder making a CSK that's oblong at best. The drilll guide eliminates this problem by given the pilot something to locate on.
Although I don't have any photos, the next thing I did was to CSK the skin rivet holes that were overthe in-board ribs that support the wing walk doublers.
