Just came across your channel and saw the wing spar video. It took me 5 years to build my RV8 while working a full-time job, and more. Keep plugging at it because the RV8 is the most fun airplane I have ever flown. My first flight was about this time last year so I am still learning. Best of luck in building
Yes welcome back and thanks for taking the time to put the video together! Lord knows it's hard enough sometimes to just find the time to work on it let alone record, edit and produce a video.
The biggest issue with chattered countersinks is that they cause stress risers which will lead to cracking, which is bad anywhere, but especially bad on the wing spar.
hey mike, yea, i haven’t done any work since my last video but just finished moving halfway across the country a few months ago and just about have the new garage set up. i’m hoping to get back at it very soon! congrats on finishing up your empennage!
Quick question Sean. Did you drill those nutplates holes to final size before you countersink them? Also I noticed that you installed the nutplates before you counersink the screw hole?
Great question, I did not drill them to final size, once you countersink it to the proper depth it opens the hole up enough for the screw to fit. And yes I riveted the nutplates on first as the plans instruct. This allows the pilot to be guided by the nutplate so as not to elongate the hole or create chatter. Because a #8 countersink pilot won’t fit in the nutplate they tell you to use a #30 countersink for those and a #40 countersink for the #6 screw holes for the inspection cover. Some builders have just fabricated a thick piece of scrap to place beneath the hole and countersink before installing the nutplates but honestly that would be a lot of extra work and the nutplate method worked great so I would just do it that way

That tape idea is a great one! Thankfully I have a huge surplus of that stuff. lol

Your building my dream plane! I'm looking forward to watching your progress.
thanks! I need to get back out in the shop, been way too long since I've worked on things
Nice video with lots of useful information. Great work.
Thanks, Glad it was helpful!
Welcome back dude!
Thanks, it’s good to be back to working on it!
Why is it worth taking time? What happens if you have a “chattery” countersink?
The biggest issue with chattered countersinks is that they cause stress risers which will lead to cracking, which is bad anywhere, but especially bad on the wing spar.
Sean are you still building? Been awhile since you had any updates. I'm just finishing up my empennage, wing kit gets here next week.

@@pilottender That's great and congrats on the big move!
Whoops Hoo, Shawn! (Sean?)
I meant "whoo hoo"!
Couldn’t let you be the only famous one on the internet, though I don’t anticipate an imdb profile anytime too soon haha

@@pilottender thank you man for the detailed answer
6:00 do you then prime or do something to the exposed metal after the counter-sinking?
Yes, I just used a rattle can primer to prime the area i countersunk
