I have seen that people invent at least 10 different ways to countersink the tank attach screw locations on the spar. This seems to be done because the hole gets too big and problems follow because of that.
Vans say in the instructions to use the nutplate as the pilot. And to do this, they say to rivet the nutplate on first and at the last moments, the pilot of the bit will center in the nutplate and all will be well.
Why do most people not do this and invent all these ways to countersink the spar?
I did mine the Van's way and they turned out perfect so what is all the fuss about?
