Brief Description:  Vertical Stabilizer Fiberglas Tip

Most of today was spent mounting the vertical stabilizer fiberglass tip. A short piece of aluminum angle was used to align the rudder with the vertical stabilizer. The angle held the rudder in position while external fixturing was clamped and taped in place, to more rigidly hold the rudder in its neutral position while the stabilizer tip was aligned and mounted. After the external clamp was securely in place, the aluminum angle was removed because it would interfere with the closer rib.

It took several iterations to figure how to correctly position the closer rib and to get the fiberglass tip sanded so it fit well. Before drilling the stabilizer or fiberglass, a strap (not Shown) was wrapped around the trailing edge of the tip to the front edge of the stabilizer, then pulled tight to force the front edge of the tip tightly against the inside of the stabilizer leading edge. The trailing edge of the tip was also forced down against a ¼” thick spacer on the top of the rudder.

After checking the alignment of the trailing edge of the tip and rudder with a laser, the holes were drilled to #40 and clecoed together.

Tomorrow, the rear edge of the tip will be trimmed back about 3/16” and reformed with epoxy and flox, because the tip is a little too long.
