- Finshed deburring trim tab skin - Riveted the bottom trim tab - Riveted trim tab horns to trim tab - Fitted trim tab and hinge to left elevator - Trim tab horns were tough to because I had final bent the skin close. Used my "Main Squeeze" squeezer with a 3/8ths and 1/8th flush set on a 3" yoke to set the rivets. - Used the 4" No-Hole yoke to finish setting rivets for the trim tab horns - Used the Longeron yoke to set trim tab skin bottom rivets to trim tab horns - Note: had to rivet the horns first then rivet the trim tab spar. This was due to limited access to the horns with the spar in place.
