- The right an left wing structures are built, including hours of tedious deburring, straightening, and priming...
Huge milestone on this one, and I'm incredibly proud of how they came out. The wings on this build are coming together quickly, and I couldn't be happier.
The wing structure is first built to test fit and final drill all holes, then the entire thing is stripped back down while the pieces are cleaned, smoothed, and straightened. They're similarly scoured with PreKote and then sent to the primer booth for a coat of epoxy primer. After that, it'll all goes back together for riveting.
Before we finish the episode, we mount the wings upright for the remainder of the work, ensuring they're level in every plane and straight, as well as free of sag.

PreKote is the solution that I pretreat my aluminum with prior to priming. It's good stuff!
Scotchbrite Wheels: www.cleaveland...
These are the smaller wheels for the Dremel. I went through three or four. Try not to wear a groove in them, adjust positions and wear evenly.

This is the big guy for the bench grinder. Same note about wearing grooves.

I'm Ryan, an aviation enthusiast who has decided to build his own aircraft and publish the entire thing online for others to watch along. The airplane is a two-person experimental kit built aluminum plane capable of over 200 miles per hour, and a range of nearly 700 miles. The kit is manufactured by Van's Aircraft, one of the most prolific kit providers on the planet. The airplane is aerobatic, functional, and fun. The build is challenging, time consuming, fun and rewarding.

Awesome work bro. Watching from Australia. Would love to build my own some day.
I'm extremely fortunate to be able to take this on! Such a wild thing to be doing, but so rewarding and fun!
I really enjoy watching you solve problems and strive for perfection. Thanks for putting this online.
Thanks so much, Ed!
I’ve got tons of practice problem solving because I cause myself a lot of problems!!
Seriously, thanks for your videos. I'm just at the beginning of my 8 and I'm too old to waste time figuring half the stuff out. Lol
Ah it’s not too bad! The problem solving is half the fun!!
Good luck on the 8!
Milestone... great job.
Thank you!
Wow! I can’t believe how fast you were able to get the ribs completed. Nice work. You’re definitely in a groove.
Few days off from work didn’t hurt. I need more of those!
It was a slog, but I was able to just grind through it pretty good.
@@RyanFlysPDX No better reason to take vacation days…except to fly.
Great attention to detail. You didn’t prime the main spar. I realize it is anodized, but you did a fair amount of machining on it. A question of better the enemy of good enough?
Any where I removed anodization from the spar-be it accidentally or through countersinks and machining-I’ve gone through and spot primed with a swab and a small canister of primer.
Last thing I want is a spar left open for corrosion!
Initially you started building the wing from the spar on a flat surface then went to that weird trapezoid crap stuff with comical central pillar. The wing should be built off a flat level frame.
Typically, you’d be spot on. But Van’s kits are all CNC punched, so the measuring and engineering has been done-it’s nearly impossible to build a warped wing. Once everything is tied together via the skins, some careful measurements are taken to verify there isn’t any washout and then the riveting gets it done from there.
Building a wing like this without prepunched skins and structure would surely result in a distorted wing and an unsafe airframe.
Why couldn't you use the large holes already in the ribs for wiring instead of drill another small one?
Good question-I’m guessing this is related to the holes for wire runs. The wires have to be secured, either in conduit or with wire clamps and bushings. The large holes wouldn’t retain the wires enough, so you would have to install separate wire retainers or clamps on each rib.
It’s possible, and people do it, but I chose this route. Each has its benefits and drawbacks.
Can you use wood
minute 15:05 - How is the material called you are using for cleaning?
That’s called PreKote. There’s a link in last weeks video, I’ll add another to this one later.
It’s a pretreatment for priming, scoured on with Scotchbrite and then cleaned off and wiped down with acetone or isopropyl alcohol.
Thank you
@@RyanFlysPDX I saw that red Scotch Bride has the medium thickness and there is also a black ultra fine. have you tried different ones? Is the red the one you use for everything?
