Bottom Rudder Assembly pics - Hole in Forward RIb Flange Drilled Out

And now for some pics as promised. Bottom rudder assembly all clecoed in place. The rib, the front spar, the HS 710 Support bracket (with the large hole on the back side), and the HS405PD Angle bracket, all in place. the two small holes in the bracket are where the control cables from the rudder pedals will attach to the rudder. Sure is nice to have a viable part again so I can complete the rudder business adn move forward again.















Next is a blurry pic of the front portion of the forward spar, with the support bracket adn everything else attached. Still need to finish drilling the two holes on the bottom to finish the small shim that sits behind the bracket to level out the attach points where the rib flange butts up against the sterring bracket. All these holes need to be final drilled and deburred - will happen today. The nut plate has been installed on the wrong side for now - will probably drill the rivet holes for this while it is in that position, and then remove it and place it in the correct position behind the forward spar when everything gets riveted into place. The pic is sideways for some reason - bottom is on the left - AAARGH!


And lastly - a pic of all the different drill bits I used to step drill the hole until I got it up to 1/4 inch so I could switch to the unibit and finish drilling it up to 3/8 inches, which is the diameter of the hole needed to fit the rod end bearings into the nut plates. I checked the hole after each drilling to ensure that it was still centered and round.
