Countersinking the longerons made me nervous when I did it for the rivets that attach the fuselage skins. But it really makes me nervous countersinking for the empennage gap fairing, which attaches using #6 screws.
You have to create a pretty deep countersink for the fairing to sit flat.
Here's a couple of pictures. You can see that my fairing still doesn't lay flat against the longeron. Should I go further with the countersink? Is there concern about weakening the longeron if I go further?
Thanks,
