Rudder Trailing Edge Wedge
How did you drill the #40 holes perpendicular to the cord of the wedge?
|
I used the extra length that was cut off and reversed it putting the two pieces together so it created a flat surface.
|
Cleaveland Tool makes a nice tool to make this job easy. About $25, I believe.

EDIT I misread the original post. As Scott explains below, the tool I list in the link should only be used when countersinking the holes of the trailing edge and not for final drilling the #40 holes perpendicular to the chord line. Sorry for the misinformation.

The desire is for the holes to be final drilled perpendicular to the cord center line. Not one of the sides This tool is aligning the side of the wedge square to the chuck (if used in a drill press), so it is fine to use in place of the simple method described in Section 5 of the construction manual, for doing the machine countersinking of the wedge, but not for final drilling. |
I used a wooden block cut to the angle that would make the drilling 90 to the cord and the back side of the block is set for flush for the counter sinking which needs to be 90 to the surface and not the cord. I have no use for it anymore and if you were nearby, I could just send it out to you.
I may have the measurements (angle) for the cut and will look it up tonight. |

When counter sinking, as azflyer21 & Scott mentioned, I reversed the extra cut-off wedge placed under the TE wedge should provides a perpendicular to the TE wedge surface. |
This template is cut to the angle specified in section 5. |
I used the table saw to cut the appropriate angle on piece of 2 x 2 lumber- one for drilling the holes, another for the counter sink.
