Wouldn't this be the best case scenario for this design since most of the force is transferred into the frame via the pneumatic cylinder? Or have I just been working too many night shifts?

(Awesome PPT force diagram below)

Either way, I don't think the lever arm for the bending moment on the cantilevered shaft changes since the force isn't any farther away from the frame rail.
