Has anyone tried this?
I am preparing to drill the rudder T/E tomorrow. I set the lead edge on blocks to position the trail edge level in the horizontal plain. I then duct taped a bubble level to my air drill in line with the #40 drill bit, By holding the drill level using the bubble I know I will be drilling the hole perpendicular to the cord line of the wedge. There seems to be lot of ways to do this task but I can't think of an easier or more precise way.
