Brief Description:  Pitch trim servo hardware pre-install

Before I can install the aft upper skin, I need to finish off some more details - the pitch servo hardware is one of those details. First off, the bellcrank is removed and the servo pushrod attach hole is drilled. Of course, the pushrod itself is also made, but that didn't take very long as there are only 5 parts. I noticed as I was playing with the rear stick that a full left aileron input went to the stops, but a full right aileron input was binding a bit and I couldn't get to "full throw". After pulling out the intermediate pushrod (F-840, I believe) I noticed that the rod ends were not in alignment with each other on the pushrod, so I un-torqued the jamb nuts and re-torqued them in alignment. I believe that fixed it, but won’t know until after reinstalling the pushrod. But, I won't actually install them again until after the aft top skin is installed becuase the wood floors that the "bucker" (Bob?) will be laying on will lay over the bellcrank and the aft pushrod will be in the way. I went ahead and hand tightened some of the bolts, washers and nuts for the pitch servo just because. I will call this one good for now.
