20. Carefully sand from the edge of the tape for-
ward to the centerline at the front of the fin using
progressively finer sandpaper either against a flat
surface or with a sanding block. Begin with 180 -
220 grit paper to approach the appropriate wedge
shape, then finish sharpening the wedge with a
320 - 400 grit sandpaper. Using too aggressive
a grit of sandpaper risks overshooting the target
shape.
21. Remove the tape from the front edge then re-
peat the taping process on the aft edge of the fins,
placing the tape so that it goes from a point 3/8"
(10mm) forward of the aft edge near the root to a
point 1/8" (3mm) forward of the corner at the aft tip
of the fin.
22. As with the forward edge of the fin, sand from
the marked centerline at the aft edge of the fin to
the tape. Do the sanding in steps, beginning with
a medium grit sandpaper and ending with a fine
sandpaper.
23. Remove the tape from the fins and saturate
the forward and aft edges of the fins with thin CyA
adhesive. Allow the adhesive to harden.
24. Sand the edges once more using a fine sand-
paper to produce a smooth surface where the CyA
adhesive was applied. The rest of these instruc-
tions represent the standard – flat – fins for visual
clarity. The steps are the same whether the fins
have been airfoiled or not.
