- The wings on my CH-750 Super Duty are coming along nicely. By the end of this video we will be ready to rivet the bottom wing skins.

Addicted to these AWESOME videos!!!
Thank you! Glad you enjoy them.
Me too! Keep the excellent video coming!!
Mark, this is where you need the air drill. Fully understand the tripping over hoses concern but much higher RPM for cleaner, quicker holes
I can tell the softening and de-burring process is very ZEN for you.
Deburing a thousand holes is the best part of airplane building! (said no one ever LOLOL!!!)
I don't remember seeing the nuances about not riveting on these small pieces in Zenith's SD wing build videos. Thank you for bringing these to light
That Deburring tool is a great tool and my favorite tool for years!
I’m impressed with quality of this kit. Seems pretty sturdy with all the rivets
As a kid I always thought I was weird for liking peeling my skin off after getting sun burned... good to know I wasn't alone in that! Oh and the rest of the video was great, too. :)
Putting two fingers down to hold all layers firmly together when match drilling is a great tip, especially when you have to open up holes on an assembly that has already been partially riveted since you can't take it apart and deburr anything.
Endless holes to drill. All part of the process of making this aircraft really yours.
Oh and great job. You are taking the anxiety out of the thought of building my own aircraft.
You can do it Doug! As I've said before, don't worry about not knowing something-you will learn as you go and you will have a blast doing it! The reason I keep building so many airplanes is because it's so rewarding. Get that kit ordered!
Great video and a lot of learning as usual thanks a lot sir
I generally put more clecos in as that keeps the skins tight during drilling.
Ah the fond memories of youth, like peeling the skin off your back.
It's the best part of sunburn!
Excellent video with excellent detailed tips. Truly enjoying this channel Mr. Mark. 😄
Thank you!
Once again a great video Mark! Thanks for all the'tips' , looking forward to more.... Blue Skies!
Very good instructional video. Zenith could not do better!
Thanks for the detail
Excellent video.
Another well done episode Mark. Really enjoying the process. Your a great teacher!
Excellent video,
Thank you.
Good stuff Mark!
Looking good man.. ill stop by soon
Very pleasant and helpful video, as always😀🛩🔝
Sorry Mark. I would have helped clean up, but I was watching Episode 11 and I fell asleep. 😪😪
Hello Mark. Thanks for another great video. The An3 bolts are these torqued to a specific figure and do you use locktight on them.
Well, if your current career tanks, you could probably get a consulting gig with Zenith. Your attention to detail is beyond any other aircraft video series that I've seen. There's a guy named Walter Sorels that makes knives and swords professionally. His videos are very much like yours. The Northrups that have hours of photography and drone instructions are right with you, as well. A good teacher is a great asset. Thank you for doing this.
@@lufasumafalu5069 no, he's just motivated. He talks about having a career often.
@@lufasumafalu5069 I believe he is either an engineer or works for a flight mechanic company. He never actually said what his job is, but he is employed and discussed his background.
Excellent, as always. Thanks. I wonder why you don't use a drill guide to ensure your holes are exactly square to the skin and rib.spar?
I had thought about that, too. But thinking more, it doesn’t seem like there is enough thickness for it be an issue.
I don't know which camera you are using, but I am sure there are settings for different focus modes. If you can go for a single focus point in the center and the camera will ignore the background. For your videos it might be ok to use this setting for all shots so you don't have to change the setting all the time. Thanks for your videos, I am about to order the rudder kit for a Cruzer and this is all your fault ;-)
I can turn off the auto focus, but I didn't realize it was focusing on the cleco until I uploaded the footage and started editing it. Of well, I figure by the time I make my 1,000th video I might actually know what I'm doing LOL!
Nice, you are making good progress. Are the fuel tanks welded, plastic, or are you going to have to assemble them with proseal ?
The fuel tanks are aluminum and pre-built by Zenith.
When you have multiple skins like on the wing, how do you determine the overlap pattern? I know you want the skins forward to overlap the aft skins such that the air flow goes over the "step down" in the seam, but what do you do inboard to outboard of the wing? Does it matter when the overlap is parallel to the air flow?
Good question, I didn't think to mention this in the video because the order of the skins is shown in the plans, and in the instruction manual. There's a lot of good info in those plans and manuals! Zenith does their best to make this an easy to build kit!
Man if that order is not told to you in the plans I wouldn't buy the kit ... No idea what kit your thinking of that brings up a sequence question ... pretty sure they all tell sequence
Are you adding autopilot? Have you sourced brackets or will you fabricate your own? I would assume they go in the wing before you close it up?
Yes I am definitely adding an autopilot, but the servos connect to the pushrods in the fuselage so no servos need to be installed in the wings. I'm not sure yet on the servo mounting brackets. As far as I know, no one makes brackets and I think each builder has to design and fabricate mounts. I wish Zenith would come out with a factory option for this!
Hello Mark, my question is about the rivets orientation. It is obvious on the skin, but how do you determine the rivets orientation when riveting the ribs to the spar and other components of the wing structure?
The part of the rivet that gets smashed is called the "shop head". The shop head should be on the side of the thicker material. Sometimes it is not always possible due to other structure getting in the way, and that's OK.
Thank you Mark, I enjoy very much your videos!!!
How about a simple locating hole on those parts that can be accidentally installed 180 Degs.
Is there any chance we can assume you are going to smooth and deburr everything and move on???
I'm pretty sure he said he was going to strip it apart after the match drilling.
I'm not sure which part you're referring to, but yes everything is is (or will be) deburred and smoothed. I mention this on just about every video!
where will be the pitot tube (and may be angle of attack static...) ?
They go in the left wing, but I do not yet have them to mount.
@@KitplaneEnthusiast please do a detailed video section on that, thanks
@@bibrakc I will. I will also show how I install all the wiring through the wings for the lights.
Maybe you address it later in the video, but at 4:06, the fitting looks one row off from where you show it at 3:52..
You have a good eye! Sometimes I do something just "for the camera" and then take things apart. In this case, you are right, I was clecoing it on but I knew that it would come off again, so I wasn't too careful in placing it in the correct hole.
This is why I always state that builders should use the manuals and plans while building-don't rely on watching a video!
The nice thing about the Zenith designs is that most parts can not be installed incorrectly. For example, the bracket you are referring to has all 3/16" holes. If I would have tried to put a cleco, or rivet, in all the holes then I would not have been able to install them in the last row because those holes in the spar are drilled to A5 size (5/32"). This piece CAN be installed 180 degrees which would be bad, but it actually can not be installed in the wrong set of holes. Good catch though!
Mark, shouldn't you be using a better longer Level, than that plastic 12" you are using? A longer level will let you see if there is any warp or wave in the aluminum. If using small levels like yours I would have 2 or three at different sections of your wing, so they all agree.
The wing spars are straight and are essentially an extension of the level. There is no need for a longer level. If the spars are wavy, then he has bigger issues, It is pretty easy to sight down the spars and see how straight they are.
I was going to say the same thing!
Watch your six. Some day, Brian is going to come up and smack you
He already has! Lol
If the whole airline thing does not work out, you may be able to create a business called “Sharp Edges” ; We will remove all of your sharp edges for a good price!
Atop licking on Brian! 🙄
Great video! Thanks.
How long does it take to drill all those holes? I'm thinking of building the same airplane sometime in the future, so I find this really interesting.
