Hello all,
While countersinking my wing spar reinforcement plates (the "waffle" plates) for platenut rivets, I found that the prepunched #40 holes for these rivets were actually almost #30. I did a little more checking, and the #30 rivet holes for the rib rivets are almost 5/32". That makes for a lot of oversize rivet holes in this part.
I still consider myself a 'newbie' builder, and perhaps these holes are really ok. But everything I learned building the tail kit tells me that these holes are a problem - oversize holes lead to weak riveted joints.
Has anyone else noted this on their wing spars?
Thanks,
Dave
