Wing Rear Spar 15-5-4

Image
After priming the rear spars, I temporarily clecoed them to the wing ribs (ensuring the main spar was not twisted), and then clecoed the doublers and hinge brackets to the rear spar. I decided it would be easier to squeeze rivets in the doubler/bracket to spar attachment holes which were not also attached to the wing ribs, so after clecoing everything together on the wing, I removed the spar to rib clecos and clamped the spar on its side to the workbench. I also taped off holes not to be riveted so as not to make any mistakes. Final fitting of the rear spar and attachment to the (left) wing ribs prior to riveting Right rear spar and attachements clamped to the workbench Squeezing the majority of the rivets was relatively easy, however there were a few that had to be bucked around the inboard aileron hinge bracket. Bucking the rivets next to the inboard aileron hinge bracket. Easy using the longer 7" rivet set for clearance Inboard aileron hinge bracket riveted to the rear spar and

Priming - Top Wing Skins 16-2-6

Image
With another break in the recent rainy weather, I decided to start prepping the top wing skins for priming.  I will be priming only the mating surfaces on the skins to minimize the amount of primer weight added to the wings. To mask off the areas not to be primer/prepped, I cut 3mil plastic sheet into squares (sized to the appropriate wing skin sections) and taped them in place. I'll need to do this twice (once for applying EkoEtch, and again before spraying EkoPrime), although I will be reusing the plastic sheets in both cases. Inboard top wing skin masked off. I will be priming the entire skin area under the wing walk doublers, as well as both sides of the doublers themselves Outboard top wing skin masked off. I left roughly an inch for priming along the rivet lines. Next I applied EkoEtch to the skin stiffeners, wing walk doublers and top wing skins.  Skin stiffeners and wing walk doublers drying after being treated with EkoEtch Inboard wing skin after EkoEtch treatment Outboard

Wing Ribs (Left Wing) 14-5-1 to 14-6-1

Image
To close out section 14 of the plans, I riveted and bolted the left wing ribs to the left main spar. No challenges here as I had already completed the same on the right wing a few weeks ago. Ribs riveted to the main spar. Note there are 5 rivets holding each W-1011 rib in place and 6 rivets holding the W-1010 rib in place W-1012 ribs riveted to main spar. There are 8 rivets holding each rib in place W-1010 and W-1011 ribs will also have bolts holding them to the spar. These will be installed next. W-1012 ribs only have rivets holding them in 10" extension on the torque wrench came in very handy to get squarely onto the nut for accurate torquing. The second 1/4" socket wrench with 3/8" socket was used to hold the bolt firmly while tightening. Inboard wing ribs riveted and bolted in one at a time, starting with the most outboard rib Note the bottom bolt in the inboard W-1010 wing rib uses 2 washers as opposed to the one washer on all the other wing bolts. This is noted in

Priming - Wing Rear Spars 15-5-3

I again took advantage of a break in the rainy weather to prime the rear wing spars. These didn't take too long to prep and prime, I just had to be careful with handling them as they are each about 12 feet long. Rear spars drying after cleaning with EkoEtch Using packing paper to protect the primed finish while moving the spar around on the priming table Both spars primed and ready to be riveted to the wing ribs once I finish attaching those to the main spars So far with my experiences working with Stewart Systems EkoPrime in an outdoor setting, I have found the following conditions give the best, most consistent, priming results temperature - 64F - 70F away from direct sunlight calm wind (of course!) Primer used:   ~125g + 12g distilled water Time Taken:       1.7  hours Dates:                    March 20 2024 RV-10 Build Total Time:      620 .1  hours Priming Total Time:                 64.1  hours  (not included in build time totals)

RV-10 Fuselage and Finish Kit Arrival

Image
Aside from working on my wings, the last few months I have been busy preparing to receive my RV-10 fuselage and finish kits.  I originally placed the order for my fuselage kit back in November 2022 with an estimated availability date of August 2023, however with recent events over at Van's this date got pushed back. I was finally sent a final payment request in January 2024, and received the email that the fuselage kit was ready for pickup on January 31. After Van's initially announced their business challenges, I took a chance and placed my RV-10 finish kit order on October 30 2023 hoping to lock in the original pricing and my place in line, fully expecting that it would be a year or two before receiving that kit. However, in January 2024, Van's also requested final payment for my finish kit (at the same time as the fuselage kit), and I was notified that the finish kit was ready for pickup on February 21. As I had marked both kits for will-call pickup, I asked Van's if
