Vertical Stabilizer Complete!

A few more rivets, and before I knew it the first part of the build is complete! Feels great to be able to check this box, but after a short break running around the garage holding this thing up like a flag and making airplane noises (I wish I was kidding), back to work!

Actually tonight was a pretty short night building. I used my back-riveting plate for the first time, and back-riveted the skins to the rudder. It worked great! It was pretty quick work, but made it look like a lot of progress!

I think the next step before I actually assemble the two halves is to figure out exactly what I'm going to do with the rudder trim tab. A few of the parts came today (including the ProSeal for the trailing edge), so I should be able to start on this endeavor tomorrow. That's all for now!

Empennage - More Rudder/VS Work

Started the evening by running my conduit line through the VS skeleton and fabricating two small brackets to hold the conduit in place between the lightening holes of the VS nose ribs. I forgot to take a picture of them, but they came out pretty good! This conduit will allow me to run lighting and/or antenna wires up to the top fairing of the VS if need be. I also installed a doubler in the top rib of the VS where the conduit terminates to strengthen that area. I primed all the newly made parts and riveted them all into place. The final thing I did to the VS before putting on the skin was to install a grounding nut plate, in case I decide to add static wicks (still undecided on that).

Next was the rudder. We got through the first 4 or 5 riveting steps in section 7, up to the back-riveting of the rudder skins. I'm saving that until after we get completely done with the VS, which is looking like it should be tomorrow. The rudder pieces went together fairly well, and we also added the grounding nut plate in about the same position of the rudder spar. The end of tonight's work on the rudder brought us here:
Sarah getting some more experience bucking rivets... she's doing great!



The control horn/bottom rib riveted together, and rudder spar with doublers and nut plates installed. Looking good so far!

The last thing I did tonight was start work on attaching the VS skin. I had been putting this task off because I wanted to make sure I had done everything I needed to before buttoning it up. After installing the conduit, redoing two of the rivets, and putting in the nut plate, it was ready to be closed in forever! I only got about halfway through it tonight, but I think it was the harder half with all those rivets near the leading edge that were kinda hard to get to with the bucking bar. I got all the rivets forward of the front spar done, as well as all the front spar rivets on one side. It looks like the rest should go pretty quickly tomorrow, and then I'll have my first completed part! Excited for that...

The current state of the VS. All leading edge rivets are complete, and one side's front spar is done (the side not visible).

View inside the leading edge of the VS, with the lower half of rivets complete. You can also see the conduit run going through the lightening holes.


Inside the VS looking forward, you can see the lower half has been riveted to the spar, and the conduit running through the front area.

Empennage - Vertical Stabilizer - Day 1


So, today was the first day we began building our own airplane. Be warned that the caption of the below photo is a bit incorrect though, since the beginning of the build is neither called step one, nor is it on page one. It is called Section 6, which quite logically occurs immediately after sections 1-5. Sections 1-5 cover many of the prerequisites to embarking on such a project, including company/aircraft information, terminology, methodology, and just general information about exactly we've gotten ourselves into. Van's indeed seems to be very thorough in guiding their builders along, and I for one am very thankful for that! For all intents and purposes, though, Section 6 is really Step 1 for actually building something.

Page 1, Step 1!

I gathered all of the necessary parts for the vertical stabilizer, stripped off the blue vinyl protective sheeting, and began following the instructions that lay before me. I cut some aluminum angle to make R and L spar caps, and before I knew it I was neck deep in drilling/deburring, watching things take shape before my eyes!

These are the two VS spar caps, just after cutting them with the bandsaw.

The lower part of the same spar caps, beginning to get clecoed into place.



The VS rear spar, with caps, hinge brackets, and doublers all clecoed into place.


 
Adding in the front spar and the rest of the VS skeleton.





 
Clecoed and final-drilled the skin into place... just to have to take it all back apart again for more deburring, dimpling, and then priming for final assembly!


I've chosen to go with Rustoleum self-etching auto primer because it's relatively cheap, easy to work with, and my research seems to indicate it provides decent protection for the money. I considered other techniques like alodining or using a higher-dollar 2-part primer, but quite honestly I can't justify the cost in both time and money spent. Lots of planes are built around the world without any primer at all, and so I'm really not too worried about choosing this route over some other methods preferred by the primer purists-- this seemed like the best middle-of-the-road choice. For those who may not be aware, primers tend to be a volatile subject among aircraft builders... lots of differing opinions out on the forums that lead to lengthy discussions and spirited debates... me, I chose what I hope/believe is best for my purpose, but may not be the route others have taken or would/should take. Unless asked specifically, I promise this is the last time I'll discuss primers and choice/rationale here on this site!!!! ;-)


Priming is done, so that means it's time for rivet #1!!! Too bad it was for kind of a boring part: the rudder stop tabs. It was a good place to start, though. Here's the final part after putting the six rivets into place:
The first part I riveted together for my very own RV-10!




A few dozen rivets later, it was Sarah's turn to take a shot at it!
 
She's been busy assembling her Van's toolbox practice kit, but she took a quick break from that to help out with the front VS spar doubler plate. She did a great job!


After riveting the spars together and then (most of) the skeleton, we're ready to attach the skin! Time to call it a day, though. I have to say, things seem to be going more quickly than I thought they would. I'm not in any kind of rush, and would much rather take longer and make a quality build than go quickly and make mistakes... but today seemed to go very smoothly and we cruised right along through most of the steps. I can only assume that the SportAir workshops we attended are responsible for a lot of this progress made... all I can say is, if you're thinking about building a plane, take the class!
