Hi all,
I'm starting work on my wing kit (7) and I'm getting ready to countersink for the #8 screws that hold the fuel tank on. Before I bite the bullet and start drilling these expensive parts, my question is: it appears that the holes for the nutplates aren't big enough to accept a #8 screw. Do I need to drill them out? or do they get opened up when I countersink? there's no mention of drilling them out in the instructions or on any of the other website/logs I've looked at. I'm getting ready to drill them out, but can someone who has done this confirm that this is the right idea. Also, is a #21 drill the right size to drill out for the #8 screw.
thanks!
