8 JUN 14: Page 10-15 step 4: 6.25 hours
Finished deburring the rest of the tailcone parts – no pics.
9 JUN 14: Page 10-15 steps 6&8, page 10-16 step 1: 3 hours
Final drilled 11/16th hole for the tie down eyebolt:
Machine countersunk the four #40 holes in the F-1056 rudder stop brace and the four #30 holes in the F-1012E tie down bar.  Machine countersunk the skin holes of the F-1032 longerons:

Finished machine countersinking the skin holes of the F-1032 longerons.  Separated the F-1036 battery channel, final-drilled the holes of both F-1036B battery channels and deburred the edges and holes.  Final drilled the holes of the F-1035 battery/bellcrank mount, deburred and finished all edges.  Separated the F-636 bellcrank into individual parts.  Clecoed together the F-635 elevator bellcrank assembly.  Final drilled all of the holes, deburred:

With all the tailcone parts ready for priming, I skipped back to the elevator trim tabs, which I have left to complete the elevators.  Masked the inside of the E-919 trim tab skin around the location for the ribs.  Scuffed with 150 grit sandpaper to prep for bonding the ribs – no pics.
12 JUN 14: Page 9-16 steps 4-5: 1.75 hours
Completed the trailing edge bend of the trip tab skin.  Bent the tabs on the end of the trim tab skin – no pics.
13 JUN 14: Page 9-17 steps 1-4: 2 hours
Match-drilled the holes of the outer tabs into the inner tabs.  Made the 15’ bend in the bottom trim tab skin.  Cut and deburred the E-917 & 918 trim tab horns.  Clecoed the trim tab horns to the trim tab skin and spar; final-drilled the holes common to the horns, skins, and spar – no pics.
14 JUN 14: Page 9-16 steps 3-5, page 9-17 steps 1-5, page 9-18 steps 1-3: 5 hours
Completed the E-1019 trim tab.  On this one I used hardwood – red oak – for the wedge and bought carpet tape as called out in the plans.  It was easier than the other tab, but honestly, I don’t think the bends turned out any better.  In fact, I didn’t have the inside part of the wedge lined up right, so the bend isn’t straight.  When lined up with the elevator, the gap is larger at the trailing edge than at the root.  Would be inexpensive to redo it, but I’ll probably live with it:

 Machine countersunk the holes in the top flanges of the E-920/1020 trim tab spars:
Cut two 35” trim tab hinges, match-drilled the holes in the elevators and hinges.  Deburred all elevator trim tab parts.
