Assembled and installed the aileron torque tubes on the root ends of the wings. One step is to clock the arms with a 1 1/64 shim and a nice accurate way to get this is to use the end of a 1" bucking bar with a few layers of blue tape on the bottom to get the additional 1/64 you need. Have a few #30 and #12 drill bits ready as the steel dulls the bits pretty quickly. Got the remaining insides ready to get closed out by the bottom skins. Started on riveting the bottom skin on left wing. Slow going doing it by yourself so I will be rounding up some help to get these done.
