Drilling Aileron Torque Tube

The aileron torque tube sections, the universal joint, and the rear torque tube bell crank have to be drilled so that the sections and parts will mate together tightly and in proper alignment. I used the wing spar and firewall as a table and clamp plate, respectively, to hold the assembled torque tube in position for drilling the last hole through the torque tube bell crank. The torque tube bell crank and the forward side-stick bell crank have to both be aligned vertically when attached. Its a kluge, but it worked OK. The holes were drilled slightly undersized, and then reamed for an interference fit for the AN-3 bolt. Slop is unacceptable.
