I also took the tabs off of the Elevator Skin using the snips and finishing the cut down using the Scotch-Brite wheel and files.
Below the E-721 Trim Tab Hinge is clamped to the E-607PP Trim Tab Spar and drilled.
I thought this would be an easier way to get the proper alignment, looking back, I should have paid more attention to the construction manual.
The top of E-607PP Trim Tab Spar gets machined countersunk while the bottom of the Spar will receive dimples. The hinge fit on the underside of the Spar flange therefore the dimples on the skin will fit down in the countersunk holes.
The Trim Tab is all Clecoed together and drilled to final size.
The inner and outer Trim Tab Horn is Clecoed and final drilled to the skin and spar. The outboard end will get a hand formed Riblet to close the opening.
The inboard end will also get a hand formed Riblet to close the opening.
After checking the alignment of the trailing edge many times, the Trim Tab is clamped and E-721 Trim Tab Hinge drilled and Clecoed. After looking and measuring many times, I did not like how the hinge fit, although the movement of the Tab is smooth, and is not binding.
After checking the "in trail" alignment, I did not like the way everything was fitting. I will let it sit a while and ponder the overall fit. I am considering ordering a new Trim Tab assemble and do a take two on the whole assembly.
Total time this session, 5.5 hours.
