Time to torque the nuts on everything

Here I torqued the nylock nuts on each and then final drilled the holes in the center block to the floor panels and rib. BUT, then I realized that the center bolts go into nutplates (not yet installed) after you drill the holes using the center block as a drill guide. The only way to install the nutplates in the center section is to remove the flap actuator. Then it was "back to the forums" to find out whether I could reinstall the nylock nuts again after they were already torqued once. Turns out you can reinstall previously torqued nylock nuts. See this thread on Van's Air Force, especially Mel Asberrys comment. He really knows his stuff. Here is his comment: "It is perfectly acceptable to reuse nylock nuts as long as you cannot install them by hand. The locking mechanism is secondary to the nut being torqued. If you want to use them once and throw them away, that's you choice, but it is certainly not necessary." On my next RV, I will only use regular nuts to tighten the ends of the flap actuator in place in order to final drill the center block, then go back and replace the nuts with nylock nuts.
