You have created a spindle-moulder there. One of the more hazardous machines in any cabinet or joinery workshop. Prudent to take the extra precautions. I like the simple wing construction! 👍🏻

So glad you dropped this whole experiment. At least I pray you have!!!!!

First decent aviation channel I've seen. Most are just spoiled rich kids crashing their planes. Thanks for the humble love of human flight

Really good to see the project coming along so well. Great idea regarding the weight saving technique

Ian, thanks for another great video. This was nicely edited: I enjoyed watching your father knock out those spars: It reminded how much I enjoyed working with my father on home project throughout my adult life.

I'm loving this build series!

Just wanted to say I'm really enjoying your videos. I love your editing technique. Just the right amount of action vs narration.

Nice progress dude! Cant wait to see the finished product!

Nice work. Video work is excellent and like watching you work with your father...you two are quite the team. Thank you for sharing.

Great teamwork.

This one looks more like "Ians Dads life". It is really cool that you can work on this project together! Thanks for the excellent video

Brilliant, great videos

VERY NICE!

Never a good idea to wear gloves around spinning tools. Can do more damage than good. The only tool to wear gloves for is an angle grinder with wire wheel, as those really embed in the skin as they come loose. Other than my safety tip for the week, enjoyed your build video.

Keep it up!

One more thing I will add, I think one major thing about my airplane and the warping is the color of paint. The leading edges of my airplane are painted dark blue, while the rest of the wing is white. The dark blue get extremely warm, while the white... not so much. The combination between the dark paint and the aluminum is probably not the best. So if you do go forward with an aluminum leading edge I recommend just painting it a very light color. Can’t wait for the next update!

Just a range of little observations after stumbling on this... I'm aware that just building new (and probably better designed ie; all metal) wings would likely be quicker and easier, a simple single spar/single strut wing would need a work around to pick up on the original wing attach points. You may have picked up that I'm not a fan of the basic aluminium tube, ultralight wing structure, although it's easy enough to make, but it does come with a few problems that people often miss. The primary one is the bending and flexing of the tubes, and how that effects the various parts of the structure, namely the stringer that runs along the top of the ribs to hold the leading edge sheet. Very early Avids (and following clones there of) understood the flex problem, and used multiple nose riblets to try and maintain a good section to various degrees of success. When they then wanted to create a better shape, thin plywood or laid up fibreglass sheet was glued to the ribs as this material could take the compressive loads created by the wing flex. Then people started using thin aluminium sheet which would sometimes buckle from the flex, or they would use thick enough sheet that didn't seem to buckle, but this now transfers the movement to the ends (inboard and outboard) of the wing and (often un-noticed) cracking the ribs at the top stringer, or shearing the glue/rivets at the leading edge tube to sheet joint out near the tip. this is usually hidden by the fabric covering which usually only comes off after a ground loop or similar, and said delaminations/shears/cracks are usually regarded as part of the impact damage. On a different note, when the lower rib parts were made and the long skinny lightening holes where cut out, in reality those cutouts could have gone right to the join line as the lower part of the original rib would have had sufficient support, and the glue used would easily hold the lower rib by the remaining little 'stand-offs'. Also, one sixteenth (1/16th or 0.063") alloy for the tank is overkill, 0.032~0.040" would be plenty, and if you fabricated it sealing and riveting, you could probably make it from 0.025", just have all the join flanges folded on the outside, just have a look at any Piper Cherokee, or many of the Cessna wing tanks. Maximum volume without being buried inside the wing.

Looking super good! Wishing I had the time to make as much progress on my airplane. I have to say the wing rib modifications look extremely nice I would personally probably trust the t88 without fiberglass tape. If t88 fails on my airplane I will fly as good as a rock. My ribs are quarter-inch sticks with gussets

Hey Ian, this is Alan, I met your friend Steven a while back at hooks. I really enjoy your videos! One thing I wanted to mention from this video I saw, you all talked about making an aluminum skin leading edge. I have a wooden experimental plane with an aluminum leading edge (plans called for wood or aluminum) but when it gets hot out in the sun that aluminum expands and warps. It doesn’t effect the way if flys but isn’t the prettiest thing to look at and my friend who built it says he wished he had used a wooden leading edge. The warps go away when it cools down. Food for thought, y’all keep up the great work!!!

I see that M3 bumper upgrade... playa.

If you choose a well designed, optimum airfoil remind that actual contour between the wide standing ribs is different. The upper side is fatter between the ribs, if airload pulls the ceconite up, to outside.

Thanks for showing your work process in building your own airplane and making aviation improvements in general! This may be a dumb question, but with your experience in woodworking and setting the wing spars, wouldn't it have been easier / faster, and maybe even safer, to just make new wing ribs and have even more consistency in the shape? My band saw does not allow me to make a consistent shape between any two pieces of wood. Maybe it's operator error. Thanks again for the great vid.

Let us know when she will fly. We will try and make it out to the airport to see this.

New Sub.. :) Your dad did a crazy fantastic job with all the fine detail wood work. I'm anxious to watch the rest of the build. I will say however, it looks like you eliminated some of the bracing in the cabin? I'm sure you ran the numbers...

Have you thought about adding some reserve tanks in the next bay over? I mean you have it all opened up anyways and you are making custom main tanks already. Just a thought. My buddy has reserve tanks in his wings like that and although he almost never uses them, they have come quite in handy a couple of times. Empty they won’t add hardly any weight. Thanks for the content, I’m fully nerding out on this.

Congratulations pel video, he is very instructive for editing. I live in Brazil and soon I will be setting up my PIk 26 project. I watched the assembly of the wing they are mounting and the ribs, and I am wondering if it would be easier to cut into a CNC Router machine and put the already cut ribs in both of them. aluminum tubes and after placing the ribs would you weld the smaller tubes in the aluminum? parabens pel video, ele é muito instrutivo para a montagem. moro no Brasil e em breve estarei montando o meu projeto do PIk 26. observei a montagem da asa que estão montando e as costelas, e estou me perguntando se não seria mais fácil cortar em uma maquina CNC Router e colocar as costelas já cortadas nos dois tubos de aluminio e depois de colocada as costelas soldaria os tubos menores no aluminio?

Hi Ian, I’m really enjoying watching the process your going through; it’s really interesting and instructive. Question: Would it have been less work to build a new wing from scratch rather than modifying the existing wing? I’d be interested in your thoughts on that. Thanks, Eric

I forget if you've mentioned what covering you're going to use but I'm guessing Oratex if your goal is lightweight.

You’re doing darn near the design I’ve been planning, what good timing. Looks real good! What are those spars made from?

Drum sander/Spindle 3:40

Looks like the Bandsaw should have done it , in a single step skip any routering .

What glue are you using to secure the ribs to the spar?

Excellent video! I love the time lapse. Just out of curiosity, how did you come up with that wing design? I'm guessing there will not be any wind tunnel testing to determine speeds. Keep up the great work?

Your router table top needs to be much closer to the actual router bit to avoid vibration. Also, the bit needs to be sharp and the project needs to be tight to the table.

Love how the circular saw sat on the floor for ages and you just walked around it instead of picking it up ?

Did you consider scarf joints instead of butt? More difficult to do I know but much stronger. I am amazed at what the U.S. Experimental system allows you to do, in the UK the paperwork would take more time than the build!!! I just finished an Avid Speedwing that I started building in 1992 so I appreciate what you are doing.

I guess I just don't understand why building new ribs to the exact shape you want wouldn't be easier? All those glued joints and trim to fit while done superbly seem like a heavier alternative with allot of extra work and time?

Nice. How much thicker and longer is the wing going to be?

Are you going to add baffles inside the fuel tank to prevent sloshing?

PLEASE USE AN INSERT IN THAT ROUTER TABLE.

Im kind of supriced they dont use a cnc router with that much precise routing work... they are not that expensive nowdays

❣❣💟💟💘💘

I too am wondering if you just drew an "airfoil" that you thought looked good or did you use an engineered wind tunnel / computer design ?........ where are the Flaps & Ailerons ? and...... ... Baffles in that fuel tank would be a real upgrade in the fuel system. GOOD LOOKING PROJECT ! FYI: YOU NEED A BIGGER WORKSPACE... (lol)

Parabéns meu amigo meu nome é Dener e sou. Do Brasil sou construtor de aeronave experimental e fizemos umas modificaçõa em uma assa de um kit Fox que ficou bem parecida com a que vc vez gostaria de saber se vc já fez os testes e como foi Grato

What is the taildragger shown at the end of your intro?

How long are the wing ribs

Are you going to have it so the wings fold? Plus I'd like to get some of your plans can I get some from you I am thinking about finding an avid and doing what you're doing cuz I am 7 feet tall and can't fit in a kitfox

How much is wing area increasing with chord change?

Tubes are good, ask any grumman driver

What size tube are the spars mate?

What material is the yellow spar made out of please ?

What was the original wing from?

What airfoil are you going with on this wing?

What plywood are you using?

Are you an aeronautical engineer? Do you have some experience in airfoil design? I don't think I could do this stuff at all.

Could this be 3d printed?

Love the build.... but you staring at the monitor and not the camera lens is odd.

aluminum to plywood???? how

I don't understand why you didn't just start over and make complete routed out ribs of your design and epoxy them in place just like the original?? Less work and time.
