I fabricated the aft tail fairing/panel from .025 inch 2024-T3. I used clear plastic template material to find the right place to put the holes for the horizontal stabilizer tubing penetration. The upper panel has a 30 deg crease which was applied by a sheet metal brake. #6 sheet metal screws were used to secure the fairing/panel to the metal ring which was imbedded in the fabric. I alodined the metal and zinc chromated the inner surface, as well.
Drilling support tabs provisionally held by pop rivets.
