I'm drilling the holes into the flange of HS-405(rib) using the skin as a template. The 405 rib is linning up nicely as I work the holes from the aft spar, heading toward the front, to spar (HS-702). When I get to the last hole I need to drill I see that the 405 rib has "hooked" out from under the skin by 3/32s of an inch. The entire rib looks great, except for the very last hole I need to drill.
If I press against the front edge of 405 with my thumb pretty dog-gone hard, I can get it back under the skin. I could then drill and pin it in place and everything would look great.
What I'm wondering, is if there is a concern with lateral loads on the shank of a rivet. I'm pushing hard on the rib to get it in line with the skin, once it's rivetted, the force I used to push the rib into place is now going to be applied to the rivet, as the rib wants to go back to it's natural state.
With all of this occurring on the tail of the plane, do I need to be concerned with vibration creating a "sawing" effect on the rivet?
Would I be better off just trimming away the (3/32) the half inch piece of flange, or do I really need all the metal that's on the flange? The piece sticking out is 1/64 on one end, and protrudes out to 3/32 a half inch later.
Seems kinda silly to worry about a sliver of metal, but it's my butt in the seat and I want to make sure I'm doing this the best way possible.
Thanks
