Finished placing the channel rib brace (not in plans). Drilled trim skin/channel (hinge on in there yet). I then re-assembled the aileron, fully cleco'd for fit. Noticed that the tip of the inner (O/B) rib is now poking out of the trim hole and nearly impedes the trim action. Sooooooo, I'm either gonna have to order a replacement rib or see if i can create one.
