Wings On!

Time: 6 Hours

This morning I had breakfast with my buddy Glenn in preparation for helping me put my wings on. Now that the RV is at an airport I can put the wings on permanently so that I can continue to work on stuff while I wait to save up for my propellor. Since we have had my wings on and off two times before the process was pretty easy for us. We used the temporary bolts initially to hold the wings in place while I prepped for the final close tolerance NAS bolts. I had put all the bolts in the hangar freezer in hopes that they would shrink ever so slightly. I also picked up a can of LPS-2 lubricant that Vans recommends. Then I laid out several different tools, hammers and my rivet gun with the flush set in place. I started with the hard to get bottom bolts with the larger ones first. I pulled a bolt from the freezer and sprayed the shank with the LPS. Then I inserted it by hand as far as they would go followed by a few hits with a mallet. Then to drive them all the way I used my rivet gun and flush set with some duct tape on the face to drive the bolt thru. I just used a low PSI setting and it worked really well. I drove the two lower large bolts then the top followed by the two smaller bottom bolts then the top two. This process worked pretty slick and only took an hour.

Now the fun job of putting a washer and nut on all these bolts and torquing them. The large bolts get torqued to 520-630 in/lbs and the smaller ones to 80-100 in/lbs. not much to show on that process other than is was very time consuming and a pain to do. It didn’t help that it was 91° today and a little humid. After I finished I put some orange torque seal on to show that they were torqued.

There are also two AN-4 bolts that screw into nutplates from the aft side of the center section, I torqued those as well.

Fun day and felt good to sweat and swear a little while working on the RV! It’s been a while and I’m glad to be back at it. I have so many projects and tasks to do now that the wings are on and I’m excited to get at it!
