Hello all,
I'm a long-time lurker, but this is my first posting (so go easy on me). I've done a search on this but didn't find anything quite like this, so apologies if it's been covered...
I just finished riveting the skin, other than the rear row of rivets, on my HS, and overall I thought things were going pretty well for me...but after finishing, I noticed than in a few spots, I had a "pimple" (one of which, pictured below, was fairly large). I've finished the vertical stab without these issues, so I'm not sure where I went wrong here:
My questions are:
1. How did I FUBAR this? My only guess is that I didn't do a good enough job of rounding off the faceting in the flange of the ribs during prep in a few spots, and it caused the skin to deform as I riveted it together, but I want to make sure that's where to focus my energy.
2. Other than aesthetics, is there a problem with building on with a few spots like this in the skin?
3. Is there anything I can do to improve the damage I've done? I'd thought about trying to push the dent inward with a light attack from a flush set, but I don't want to make it any worse than it already is, or cause an ugly part to become an unserviceable one.
I'm planning to arrange a Tech Counselor visit when the weather in New England and my schedule align to do so, but in the meanwhile I figured I'd get the Internet's collective wisdom. Any help you can provide would be appreciated!
