Mark, >From the photo, it's not clear to me where you are mounting the motor end of the flap actuator. I would suggest that you include a walking beam from the motor end of the flap actuator to a tab on the bottom of the flap torque tube. This will resolve the pull or push force on the flap torque tube and only leave a resulting torque on the flap torque tube. A square al tube could easily be used as the walking beam. It could extend to the rear spar and be attached to the rear spar with a short link to resolve the in and out motion as the flap motor extends and contracts as well as the net torque on the flap torque tube. The result is very light structural loads to be resolved by very strong parts of the aircraft structure. The floor is not sufficiently rigid to preclude flex that could result in change of flap deflection angle.
As they say, a picture is worth a thousand words, so take a look at this link to see what I'm talking about: http://flyboybob.com/images/kr2/flapwalkingbeam.jpg. I used a very sophisticated freeware drafting package called bob-draw-pro so no comments about the quality of the drawing, you get what you pay for.
