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.

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.
