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.
