Hello, I'm thinking of replacing a rudder skin. The part of the process that I'm not sure of is match drilling the new skin holes to the existing dimpled structure. Should the pre-punched skin holes be drilled to size while on the bench or should the skin be clecoed to the structure then drilled? If the holes are drilled first and then the skin installed will it properly fit the structure? However if the skin is first clecoed to the dimpled structure any misalignment is just going to cause the holes in the structure to become oversize when drilled.
