Apr 03, 2024 R/H Wing Tip - (1.0 hour)

Category: Wings

Cleco the R/H wing tip into place and finished drilling the holes to a #30 for A4 rivets. I have two holes that are drilled to a #21. The very forward one on the leading edge. That hole is the one I started with and it got a little oblong from the cleco. The #21 bit did clean up the hole. The other hole is in line with the aft spar. I ended up drilling that one to a #21 as I was drilling the aft spar.

Mar 31, 2024 R/H Wing Tip - (2.0 hours)

Category: Wings

Hung the R/H wing tip with help from my wife and daughter. Needed extra hands to push the tip into the leading edge to get a good fit. Drilled the holes to a #40 and #30. Removed the tip to see how the holes lined up on the aluminum strips that were glued to it. One of the strips was off some and needed to get redone. Removed the strip and made a new one. I didn't think the tip would be much work but it's turning out to be,

Mar 21, 2024 R/H Wing Tip - (3.0 hours)

Category: Wings

While cutting the R/H wing tip fiberglass a small piece broke off. I used Polyfix to secure the piece back into its place. This stuff worked very well but very strong smelling. Used a hacksaw to cut the tip down a little bit more. Started to cut some .025 aluminum strips to attach to the tip. This will give the tip fasteners more to hang onto.

Mar 19, 2024 R/H Wing Root Skin - (2.9 hours)

Category: Wings

Finished drilling the holes on the R/H wing root skin to a #21, except for the holes going into the front spar and root nose rib. Those I'm leaving until the wing is fitted to the fuselage. The spar gives a little bit side to side and I want to make sure it fits to the fuselage. I did end up adding a couple of holes on the leading edge by the slat attach bracket. The skin fits nice along the leading edge with the added holes. Removed the skin and attach doublers. The cut out on the bottom didn't line up perfect to the lower skin so I sanded it to make them line up. Also sanded a little bit on the leading edge by the slat brackets. Started to clean all the metal shavings.

Mar 16, 2024 R/H Wing Root Skin - (2.0 hours)

Category: Wings

Removed the R/H wing root nose rib and sanded the edges. There was a couple of corners that were pushing on the wing skin. Reinstalled the rib. Put the skin back on and matched drilled the remaining holes. Used a hole finder for the bottom row of rivets that go through the spar. Each of the holes on the skin are at least drilled to a #40. Need to finish drilling the holes up to size.

Feb 17, 2024 R/H Wing Trailing Edge - (4.4 hours)

Category: Wings

Put the new R/H wing outboard trailing edge skin on the wing. This took awhile to get it all lined up with no holes in it. Drilled the holes to a 5/32”. I have blocks of wood on the bottom side supporting the trailing edge but these blocks of wood were covering up some holes. I matched drilled those holes by drilling a piece of aluminum from the original skin then transferring the holes to the new piece.

Jan 17, 2024 Wing OTB Trailing Edge Skin

Category: Wings

Received the R/H and L/H wing outbound trailing edge skins not drilled. Zenith said they might need to put the holes on one side so they could line it up to bend it but didn't need to do that. I'll be able to match drill it once I get it lined up with the inboard trailing edge skin.

Jan 05, 2024 R/H Wing OTB Trailing Edge Category: Wings

Talked to Zenith about the outboard trailing edge skin holes not lining up. They are sending me a right and left outboard trailing edge skins with no holes on one side. I haven't started the left wing yet but they said I may have the same problem so they will send both sides.

Jan 03, 2024 R/H Wing - (.5 hour)

Category: Wings

Continued to match drill the R/H wing upper skins to the ribs. Drilling the holes to a 5/32” then I'll go back with a #21 reamer. This leaves a very clean hole.

Dec 31, 2023 R/H Wing - (2.5 hours)

Category: Wings

Started to drill the spar on the R/H wing. Also drilled some of the ribs. For the spar I've been using a drill cup to keep the holes perpendicular to the spar.

Dec 30, 2023 R/H Wing Tip - (1.5 hours)

Category: Wings

With the R/H wing outboard trailing edge skin cleco and taped into position I figured I should make sure the wing tip fits. Started cutting the R/H wing tip with a cutoff wheel on the dremel. I had one side almost cut all the way when all of a sudden a small chunk broke off. It's on the aft section of it and will be inside of the wing but I will need to do a fiberglass repair on it. I need to add some aluminum strips on it anyways to add support for the rivets. I cut rest of it with a hacksaw blade. I recommend cutting this piece this way. It was cleaner and came out better. Sanded the edges smooth and added some cutouts where it was hitting some of the structure inside of the wing. This fiberglass tip fits very well. I still need to drill it up though.

Dec 29, 2023 R/H Wing trailing edge - (3.0 hours)

Category: Wings

I fabricated a bracket out of 6061-T6 .040 aluminum to hold the fuel lines and wiring along the R/H wing trailing edge. I made it at the same angles as the inboard trailing edge skin but when I put the bracket on the other edge the angle was off. Removed the cleco's on the outboard trailing edge and adjusted it to the same angle as the inboard skin. I reached out to Zenith if the trailing edge pieces should be consistent all the way down, they said yes as I figured. The bottom boles still lined up but the top holes are now off by half a hole. Looks like I'll need a new outboard trailing edge piece. I've triple checked the entire wing and everything else looks great. All holes have lined up great so not sure why this piece is a little off. I could probably leave as is but it will bother me not being right on.

Dec 10, 2023 R/H Wing - (2.6 hours)

Category: Wings

Cleco the R/H wing lower inboard skin onto the ribs. Cleco the fuel access cover onto the skin. Drilled those 14 holes to a #19 for #8 screws. Used a nutplate jig to drill the holes for nutplates and dimpled them. Installed 7 nutplates onto the skin and 5 on the ribs. Two of the holes in the ribs need one leg nutplates. I have those on order.

Dec 08, 2023 Purchased Nutplates for R/H Wing access covers Category: Wings

Purchased 2each MS21051-08 one lug nutplates for the R/H wing fuel access cover from Wicks Aircraft. These are needed for two of the holes. I wanted the “K” version with the holes dimpled but they were on back order, I'll dimple them myself.
Also ordered 10 each MS21047-L3K two lug nutplate for the R/H wing fuel sender cover.

Dec 07, 2023 R/H Wing - (1.6 hours)

Category: Wings

Started to cleco the R/H wing lower skins in place but realized it maybe easier to rivet the flaperon brackets on before the lower skins get installed. I'll need to keep some rivets out so I can get the trailing edge pieces installed, especially around the aft strut bracket. Removed the clecos. I reached out to Zenith a couple of weeks ago about my wing kit didn't get the fuel sender access panels. I've seen some Super Duty gets with that hole cut and others not, mine was cut. I'm actually putting the fuel senders on top of the tank but I can still use that access panel for inspections purposes. Zenith sent me the nutplates and screws but sent me the fuel access panels instead. Decided I'll just make them instead of bothering them again. Made a template and traced it onto a piece of 6061-T6 .040 aluminum.

Dec 04, 2023 R/H Wing - (1.9 hours)

Category: Wings

Wiped the areas to be primed with waterborne wax and grease remover and wiped with wax and silicone free tack cloth. Because of how cold it was outside and didn't think the garage could maintain above 65 degrees I decided to brush the epoxy primer. My test piece looked great so I figured it would turn out the same but I'm not happy with how it turned out. There is nothing wrong with the coverage just don't like it and it was harder than spraying. I had problems around the holes, primer liked to run. I learned I'll wait to spray the parts next time.

Dec 01, 2023 R/H Wing - (.5 hour)

Category: Wings

Debur and sanded the edges of the 4 jury strut angle pieces for the R/H wing. Two go to the front jury strut and two go to the rear jury strut. Sanded the edges of the R/H wing outboard bottom skin. From the factory the bottom outboard skin had something spilled on it so I'll need to sand that area and prime it. It was in between two pieces of skin so I'll need to do the same thing with the other skin once I get to that one.

Category: Wings

Drilled rest of the R/H wing bottom skins to a #21. Taped the tie down ring to the height I wanted. I'll drill the holes after I remove the leading edge skin. Opened the cutout for the strut bracket bolt a little more so the bolt can clear the skin. Cleco the trailing edge skins to the rear spar. Needed to remove more material from the inboard trailing edge skin outboard end where the outboard trailing edge overlaps it. This took awhile to get the two pieces to fit good. Cleco the flaperon brackets and L angles to the ribs. Drilled the L brackets to a #30 in the skin. Taped the skins where I'm going to prime. All set to remove the skins to sand the edges, debur, and prime the mating surfaces.

Category: Wings

I had the holes going through the R/H wing lower skin into the spar drilled to a 5/32”. I used #21 reamer to bring those holes to a #21 hole. Makes a very nice hole. I'll be drilling the other holes that need an A5 rivet using this method. First I noticed that on the inboard end I have an oval hole that looks to be an access panel. The drawings don't show this so I just sent an email to Zenith asking the question.

Deburred the holes on the L/H wing trailing edge pieces, sanded the edges on the L/H wing slat brackets, the 4 L angles that attach to the outboard spar extension, R/H and L/H wing strut brackets, R/H wing tie down ring and main strut bracket. Still need to sand the edges of the L/H wing trailing edge pieces and then scuff all these pieces for primer. Figures I would prime more pieces seeing I wanted to prime the R/H wing rear channel strut bracket that I redid.

Category: Wings

Drilled the 3/8” hole in the SD75W4-4 rear channel strut bracket with a unibit. After drilling I wanted to check the hole diameter and it measured.3800 instead of .3750. Decided to purchase a new piece and drill it with a regular 3/8” drill bit in a drill press.

Removed the 4 bolts for the R/H wing spar inboard bracket by the #1 nose rib. Removed the bracket so I have room to rivet the nose rib, L angle, and slat support angle. Installed those parts with A5 rivets. Installed the bracket and bolts that were removed from the spar. Torqued the bolt to 20 in. lbs. Torqued the 8 bolts that attach the nose ribs 4,5,6,7,8 to the spar to 20 in. lbs. Rivet the slat support angles on ribs 4,7,8 with A5 rivets. Cleco and rivet the tank Z angles, SD75W9-2 and 3 shorter trailing edge ribs to the aux rear spar, SD75W3-4, with A5 rivets. Cleco and rivet the aux rear spar to the side of the tank ribs with A5 rivets. Cleco the rear spar parts together to figure out how it goes. Drilled the 3 holes on each of the rear ribs where the rear spar attaches to a #21. They only had pilot holes.

Jul 02, 2023 R/H Wing - (2.0 hours)

Category: Wings

Figured out where each of the wing nose ribs go and numbered them 1-10. Set aside the L/H nose ribs for now. I noticed one of the washers on one of the six AN4 bolts for the main wing attach bracket spun. I then decided to check all bolts on the spar for proper torque. Probably about half of the AN4 and AN3 bolts were not torqued. I set the AN3 bolts to 20 in lbs. and the AN4 bolts to 50 in lbs.
