14-06 Flap Hinge & Torque Tube

Flap Hinge Brackets

After the marathon priming job, it was nice to start assembling the parts. I decided to try out the C-Frame back-riveting technique to set the 470AD4 rivets attaching the Flap Hinge Brackets to the ribs.

It worked pretty well, but I found that ensuring the workpiece was perpendicular to the rivet set wasn’t good enough! If the rivet isn’t perfectly perpendicular through the piece then a boot still forms! So more practice at drilling out rivets : (

I found that closely inspecting the rivet alignment and adjusting the workpiece accordingly produced good shop heads.

It is possible to reach most of these rivets with the squeezer, using a longeron yoke. But due to the rib flanges it’s hard to ensure accurate positioning … much easier job back-riveting.

This is a straightforward job with the squeezer, being careful to assemble correctly. The manual only shows the left assembly, so a mirror image is needed for the right side.
