Time: 5 Hours
I had to fly a morning trip today which gave me the rest of the day to work in the hangar. First up was to rivet the substructure of the rudder. I started with the top rib that has the fiberglass attach strip riveted to it. I used my new 4″ no-hole yoke with my pneumatic squeezer.
Once the substructure was all done I added a “chewing gum” size blob of RTV(a silicone like material) to all the rudder stiffener trailing edge ends that are already attached to the skin. This is supposed to help alleviate any cracking on the skin from vibration. Then it was time to slide the skin over the structure.
There were only 2 rivets that I just couldn’t get too, the last rivet on the leading edge, left and right, on the top of the rudder. There are several special tools that can get to these rivets but Vans allows you to use blind rivets and I figured there was no shame in using those. When filled they will look just like solid rivets after painted!
A little touch up on several spots of the primer and that will be done. Next up… Bending the leading edge of the rudder. This is a tough job as you want a nice rounded leading edge and you can easily put a crease where the spar ends and that doesn’t look good. I will require the help from my resident pro builder, Glen.
