I hesitated to post this but now after my fifth attempt to get this right I must ![Eek! :eek: :eek:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Did anyone else have trouble with the rivets on the Fuel Tank Attach Nutplates on the Main spar? Problem: I end up with the rivet proud of the surface despite the countersink being good.
I have tried:
- Flush riveting - not pushing the bucking bar into the shop end and thought I was putting lots of pressure on the factory end.
- Back riveting - difficult to get the back rivet plate in place, would be curious how others set this up if they did it this way. I already put those five rivets in so clamping the plate is not an easy option.
These rivets are too far inboard to use a pneumatic squeezer.
Section of the plans I am talking about:
Any help would be appreciated. I am going to move on because I am beyond frustrated with these. Of course the next step is to start deburring the ribs but at least I can get into the zen of that![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
