Red line is drawn on the F-1270D side skin doubler which was the surface that was interfering with the lower skins on both wings.
After marking the 1/8" gap on both wings, it was a sad moment as the wings came off so the F-1215 flaperon torque arms and F-1214 torque tubes could be removed for final drilling. (Will likely keep the wings off until the majority of the construction is completed). The flaperon torque arms and torque tubes were reassembled on the bench with the spacer in place along with the clamp. The previously match drilled holes are to remain secured with Clecos while the holes on the bottom are match drilled to #30.
Match drilling #30 the F-1214 flaperon torque tube to the two holes in the bottom of the F-1215 flaperon torque arm.
Once the bottom holes in both assemblies were match drilled to #30 the holes were incrementally increased first to #19, then final drilled to the required #12. To assure good alignment, the drilling was done from the top down and out the bottom. After the first hole is final drilled to #12 a bolt should be inserted when drilling the remaining hole.
Looking closely one can see a bolt is holding positioning wile the other hole is drilled.
The parts were taken apart, deburred then placed back in the RV-12 and bolted in position. After the right side’s parts were in place and the nuts tightened, the torque wrench was used to finalize the instillation.
