I’m preparing my tanks to get the black goop out this week and checking the fit of everything, I’ve noticed the va112 fuel drain flanges are countersunk waaaay too deep for the called out AD3-4 rivet.
I don’t know if I would be successful riveting these, as all the force from the squeezer will go onto the flange and not the rivet.
Has anyone else seen this?
I’m thinking to just upsize the holes to #30 and use an AD4 rivet?
The countersink diameter is 0.2110and an AD4 rivet head is 0.2130 so might have to make the existing countersinks very slightly deeper.
