| Brief Description: |
Lightening holes |
|
|
Adding lightening holes to the spar webbing. Marking out the exact locations before hand drilling the 1/4" pilot holes. To avoid splintering I am cutting from both sides using the drill press with the stop set to NOT drill through the entire way. Flip the spar over and finish off the holes. Over 1/2 lb weight saving per wing. |
