Combination of about 6 days of work in the shop off and on over the past month. Still in cruise mode as the wings are still 3-4 months away from being delivered. These sessions focused on prepping the right elevator skin and stiffeners for installation and riveting. So more basic stuff, edge prep and deburring, dimpling, paint prep, priming, back riveting, etc. With all the pains of back riveting on the left elevator, the right elevator stiffeners all went in without much fuss and this time it only took about 15 minutes to set all of those rivets, about 55 if memory serves correct. With the stiffeners in place, it was time to bend the trailing edges of each elevator skin to their final shape so that they lay flat on the spar with no tension. This is the same process that is used on the rudder that I completed nearly 2 years ago and the painful memories of how I struggled with that step were all too present. Fortunately those lessons which had been learned the hard way meant that this time around it was not a big deal so gently bend the trailing edges into position. With that done, I began a search for a part that I could not find anywhere. E-0001A&B are called for in the plans to be radiused and then cleco'd to the elevator spar. I couldn't find this part anywhere in my inventory. A quick Google search revealed the reason. This set of parts is from a Vans Service Bulletin issued in 2014 for all RV-4, 6, 7 and 8 models. The date is key because my tail kit was manufactured in 2011 and as such, did not come with these parts. The plans I am using are the latest plans which call for these parts to be installed as part of the build since this SB is now incorporated into the build. This is the same issue I dealt with while building the horizontal stabilizer. So I was already familiar with blending parts from 2011, 2014 and the most recent plans. So a quick visit to Vans webstore and I have the parts for this SB on their way to me in a few days. With that mystery solved for now, I went ahead and prepped the two end ribs that go on the outside of the elevator and form the structure to hold the counterweights. This involved edge prep, straightening and fluting of these two small rib pieces. The plans have you complete that and then cleco them into place on the elevator. The holes took a bit of coercing to get into the right spots but eventually they all lined up and each was drilled to final size. That makes a good stopping point as I wait on the new parts from Vans and at this point, I probably need to think about acquiring a drill press to properly drill the counterweights. I've managed to get through the build so far without one but it might finally be time to invest in one as they have quite a few uses.
