The drill jig is designed for wedge strips used in the trailing edges of control surfaces found in a variety of Vanís aircraft models such as the RV-14 and RV-10. It simplifies countersinking by providing a more stabilized surface area on which to rest the countersink cage. The jig also helps assure that drilling/reaming/countersinking is done at the correct angle since those operations can be done with tools held at a right angle to the jig/wedge surface.
Identify which side of the jig to use. The side marked "14" is for the RV-14/14Aís elevator wedge strips, the other side is for all other wedge strips.
Secure the jig to your work surface. The recommended approach is to clamp the jig to the table of your drill press.
Position your wedge strip in the jig with the thick edge in the deep recess. Align the holes in the wedge (or marks for drilling) with the holes in the jig.
Drill/ream/countersink as needed.
