the plans often say, "dimple all the holes in the skins" but I've heard some differing opinions regarding the holes on the leading edge that will accept pop rivets after the skins are rolled and shaped. If you opinion is that they should NOT be dimpled, why not? seems that some have had clearance issues even when careful attempts are made to rolls the skins well. Is there any harm in dimpling beneath a pop rivet head? wouldn't it just allow the rivet head to seat closer to the skin, thus decreasing the chance of a clearance issue when articulating?
