Section 8 Begins: The Horizontal Stabilizer

 Now that we have finally completed the rudder, we are onto the next section.  This section, the Horizontal Stabilizer is much bigger than past sections we have worked on.  I had to run down to my storage unit to pickup the pieces, and I ended up having to get creative.  If you plan to put your parts into storage like me, I recommend trying to keep the longer parts at home, it's just easier than getting back and forth.  Smaller things like tail cone parts, skins, and other pieces are easier to transport.

The HS Spars are a bit long....

Despite the creative method to get parts home, I was ready to go and didn't wait long.  We reorganized my workbenches into a lengthwise arrangement and got to work cleaning up a bit.  It's amazing how much dust, debris, and other crap gets stuck under the tables when they aren't moved for a while.  It was nice cleaning up the garage before moving on.  The first page had me getting the doubler setup and the spar match drilled.  It was extremely straightforward and didn't require any heavy lifting.

After doing this, it wanted me to disassemble, prime and rivet.  It is a tiny batch of parts and I didn't want to bust out my priming setup for nothing.  The next page had me cutting down the spar caps, stringers, and the doubler for the other spar.  I decided to move onto this section and prep all of these parts.  This would give me a larger batch of parts to prime at once.  The parts weren't hard to cut down, it was similar to the same thing I did on the Vertical Stabilizer spar.  

I also got to do my first bearing of the project.  This was pretty straightforward and explained well.  It had me cleco the sections together and then rivet everything together.  It required me to clamp the parts down to avoid any warping.  The flange parts are all done and ready to get mounted after priming.

Completed Flange Bearing

Next week I will complete deburring the stringers and spar caps.  Then we will be ready to prime everything together and get to riveting.  This part should move quickly and once I have the priming done, we will get to assembling everything.  Also on my list of things to do is a trip to Lowe's.  I need to pick up some wood to make the stands for assembling the Horizontal Stabilizer.

The "Before" Picture.... The End to come in a few updates.

Section 7 : Complete!

It's crazy to think that only a year ago I started this process of building.  Despite some breaks in progress for work, family, and other things, I am amazed that we have completed two sections at this point.  Now that we have finalized much of the "Workshop" setup, Storage arrangements, and time allocation, its time to get the ball rolling.

So back to the headline, the Rudder is done!  We last left off where we completed the trailing edge, mounted the counterweight, and now we finished the leading edge.  The leading edge is where the two skins are rolled together to allow the rudder to maintain its aerodynamic efficiency.  Section 5 which describes many of the basic techniques that are used in the build has a rather small paragraph about how to roll the skins together.  It essentially says to duct tape the skin to a pipe, roll downwards, and keep pressure on the spar.  After making the basic roll, you manipulate the skin to finish the roll.  After rolling it, you match drill the holes, debur, and rivet together.  It really makes it sound extremely simple, but I didn't find it as such,

Rolled Leading Edge Section

The RV-10 directions describe this step pretty simply, by telling you to do it in sections and use a 1.25" pipe.  That was about all the notes it provided.  When we did this at Synergy, it was on a small test kit which used a small broom stick.  It was all the same chord and didn't variate along he spar in width, the RV-10 spar varies along the length.  So suffice to say the practice kit wasn't as realistic as I would of hoped.   I tried the tape with a pipe, used a broom, and than man handled it a bit.  It ended up coming out pretty decently, and I was able to cleco the skins together.  I let them all sit for a little while in the form of the rolled joint, and then drilled them.  It was definitely not as simple or smooth as I would of expected based on some feedback online.

After riveting everything together, it was off to the races to clean up the skin.  I quickly wiped down all of the surfaces with some acetone to remove any oils before storage.  The Rudder is now moved into storage along with its counterpart, the Vertical Stabilizer.  I also removed the Horizontal Stabilizer parts from storage.  It was quite interesting since the Horizontal Stabilizer spars are significantly longer than the parts I have dealt with so far.  I ended up having to put them through the rear window of my pickup truck and hold onto them for the short ride home.  After some redesign of my workspace and cleanup, we are prepped to get ready to go on the horizontal stabilizer in the coming days.

Chapter 528 2023 Meeting

 So I definitely wish my EAA chapter was more active like I hear other ones are.  My chapter hasn't met for quite some time.  It's really disappointing to me as I want to get to know these guys and hopefully have them come assist or give me tips on my build.  Many of the people who come to the meetings I am finding are not actually builders, but many have bought completed RV's or other homebuilts.  You hear lots of chatter about people needing an A and P or looking for someone to look over the plane.  There is one person who is kind of the tech counselor, he is actually the RV-10 owner thats local, so that is a great benefit as a resource.  The other person who runs the chapter built and RV-7 and had built another early generation RV years ago.  So I am hoping to get these two to be more involved and lend a hand at times.

So we met up at the hangars out at FOK last month and got to chat and relax awhile.  A builder who is just about done with his Sonex showed off his build.  His build just did Taxi testing and is doing some final cowl work now.  He is excited to get that process going.

Another person I met was someone building an RV-12 based out at Mattituck.  He's a retired career helicopter pilot between the military and police department who is now enjoying the extra free time he has.  He's been making good progress on his kit and has a lot of the parts on hand so he isn't being delayed by much.  I am eager to see how his build progresses and hope we end up visiting him later this summer and seeing his project.

NY, especially downstate, has a serious problem with hangar availability and the cost of that.  Between the efforts to close the East Hampton airport, and the serious influx of traffic, the hangars are hard to find.  The guy building the Sonex was on the waitlist for 5 years before he finally got offered one.  I guess I need to get on the list, but I don't want to get a call and be unprepared.  

We all had a nice afternoon and had some pizza over our plane chatter. I am hoping that COVID is now over, we will meet a little more often and the guys who are actively or have previously built will get a bit more hands on with helping or pointing me in the right direction.  I really want some extra eyes to give me tips, feedback, and insure I am moving in the right direction before I get into the really big and expensive pieces.

Rudder Trailing Edge and Counterweight Completed!

 So June was quite the whirlwind.  Between school wrapping up for the year, the kids being home part of the month, and work being extremely busy with summer travel starting, there was just not much time to build and keep my sanity.  I ended up taking much of the month off to spend time with the kids and focus on the things that needed the most attention.  Finally, after some time away and finding a free moment, I finally got to the trailing edge of the rudder this week.

Backriveting the trailing edge

My Cleaveland Tool kit had a squeezer attachment for the trailing edge included in it. I've heard some mixed opinions about the tool from the forums and other builders online, but I wanted to give it a shot myself.  I took the first rivet and tested using the squeezer attachment only and wasn't 100% happy with the result.  So I then went to the old fashioned method which was taught in the Synergy class and riveted with the mushroom set on some steel angle.  The steel angle made it easy as I didn't need to constantly reposition the rudder assembly over the small backrivet plate.  This allowed me to basically do one entire half at a time.  

Squeezing a few of the rivets that needed it at the end.

So my final setup to do this was the angle iron of steel on the table edge, the rudder over that, and then my wood and block on top to hold the rudder down.  This worked really well and I had mostly great results.  When I finished the normal back riveting, I noticed a few had a little proudness on the shop head, so I squeezed those and it finished setting them perfectly into the dimples.  So I think the final result was a hybrid of backriveting first and then squeezing to clean up the final result.  This seemed to be the best result, and sounded pretty much like what Austin did from Youtube.  

After taking on the trailing edge, I moved onto the rudder counterbalance arm.  This involved installing a counter weight, drilling my first nutplate, bending the skin to cover it, and then final assembly.  The directions spell out the method pretty well, but it takes a little finesse.  I bent the skin like it said, clamped the wood on it, and did the hammer method.  I wasn't thrilled with how many hits it took to get the bend desired, but it stated an 85% bend in the manual.  I got about there and then started working on the final bend and nutplates.  Using the screws to dimple the skin for drilling was a simple process that is pretty smart when you think about it.  I made the drill holes and dimpled everything up.  After I figured out how to drill the nutplate, it was smooth sailing.  Overall, I am happy with the final result, I am not sure if I should of made the skin a bit tighter to the weight, but I guess I'll find out down the road at final assembly.

Bending the skin around the Counterbalance Weight

Hammering the skin crease in.

After I finished the counter weight skin, it was time to roll the leading edge, the last step of the Rudder assembly.  Section 5 calls out for a 1 inch pipe, but the RV-10 manual says use a 1.25 inch pipe.  So a trip to Lowes was in order to get the correct pipe.  My reading, Youtube review, and other resources all have very mixed opinions on the pipe size and method.  I have seen some use clecos, some use duct tape, and others use brute force to get the roll.  It's not the most simplistic idea when looking at it, but I am sure I will figure it out.  So off to Lowes and then we will close out the Rudder for good.
