I got an early start today and made the connecting plate that connects the flap actuator channel to the seat back cross member.  There are 2 approaches to this called out in the plans.  I chose the one that looked the strongest and that was also the most recent version.  The F-767 plate is match drilled to the cross member for 2 #8 screws and attached to the flap actuator with 3 #4 rivets.  Keeping with the pattern of using flat head screws and rivets on everything you can touch, I decided to dimple and countersink as necessary.

The flap actuator channel serves as a housing and support of the flap motor and integrated jack screw.  It extends forward from the seat back cross member at the top to the floor at an angle somewhat steeper than 45 degrees.  I made the attachment angles that attach the channel to the floor.

The attach angles are riveted to the bottom of the flap actuator channel, again keeping everything flush.

At the upper end of the flap actuator channel are 2 heavy brackets that are drilled to accept an AN4 bolt.  The bolt fits through just opposite the direction of the arrow. 

With those fabricated and riveted in place, the flap motor was ready to install in the flap actuator channel -- I thought.

So, there it is (the flap actuator motor and jack screw assembly) installed in the channel  Hmm, if you look closely, you will see that the smaller bracket has been turned around.  Oops! 

Actually, I had to make a new one.  I had fabricated the old one exactly backwards (mirrored) from the plans.  Well, I think was Bill's fault, but I'm not telling him that!
