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!
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.
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.
@@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?
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.
Watching this while I’m getting ready to start assembling my RV8 wings. Thank you so much for showing the process and even including your mistakes.
The wings frame up quick! They’re exciting!
Milestone... great job.
Thank you!
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!!
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!
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!
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.

Why couldn't you use the large holes already in the ribs for wiring instead of drill another small one?

Can you use wood
