Hello,
So I am working on the empennage kit, specifically in the tail cone section and trying to get these rivets right and no matter what I do it appears that I am forcing the rivet to expand in between the sheets of metal being riveted.
It isn't more then a 16th of an inch, more like a 32nd. I have tried drilling them out and using a vice grip to hold the metal together without much luck.
Looking for advice as to
1 - Is this normal (I suspect no, but just in case)
2 - Is this acceptable and safe or is this a MUST drill and re-do error?
3 - How to avoid this?
(Note, I have been diligently de-burring and clearing out chips and I always have a cleco on both sides of a hole that I am riveting to hold it in place.
Any help here would be great as I need to get this tail cone done this weekend as the wings are arriving via freight on Monday.
