Sect 9-24, Step 1 & 2: Bent hinge pin to nest into channel at Inboard end of LH Elevator. Relatively easy to bend this "wire" (vs piano wire I've used before on R/C planes which is heat treated and tends to break at sharp bends). Drilled 1/16 inch hole adjacent...ready to safety wire once Trim Tab is actually installed.
Jumped ahead slightly to Step 5: Pitch Trim Servo Assly. For the #27 size holes, used #6 screw dimple dies (tested first with sample material same thickness...screw head fits well). Then Countersink six #40 holes that attach the support C-channels. I first tested depth on sample material (0.032")...key since thinner material than typically countersunk. Happy with results.
