In Step 3: ..."Final-Drill #40 all the holes common to the skins and trailing edge..."
Also, ..."Final-Drill #40 all holes common to the skins and flanges of the R-903 Tip Rib and R-912 Counterbalance Rib."
It appears that all these "holes common", along with the substructure holes, have already been punched to size at the factory since the #40 bit easily slips through them. My builder number is 140805, so it's a pretty recent kit.
Could it be (with the evidence before me) that I don't need to final-drill these holes? That they could be ready for deburring (if needed) and dimpling?
Any commentary is appreciated.
Thank you.
