Brief Description: Trim Tab - 05 - Finished Building Trim Tab
- Final drilled trim tab hinge to trim tab spar and skins (after aligning with elevator). - Took assembly apart and deburred / dimpled all holes. Decided to dimple the hinge and spar versus countersinking. - Cleaned, prepper and primed all the trim tab parts. - Trimed the hinge to size and radiused corners. - Riveted the trim tab horns onto the trim tab. - Decided to pop rivet the bottom trim tab spar. The Z spar's flange on the bottom faces in. Even with pulling the elevator apart it would be difficult to buck and rivet those rivets (not impossible but worth the $3.30 (x15: MK-319-BS @ .22 cents ea. plus shipping)). - Installed the trim tab hinge on the spar and riveted it. - Put pop-rivets in both ends of the trim tab (CS-4). - Scuffed and prepped the trim tab for primer. * Finally - as it turns out, 2 times is the charm. Its Done!
