Hey again all,
For those keeping track, I started installing the platenuts on my spar over the past few weeks, and I'm just about done with this step. Though most of them came out pretty well, there are a handful of rivets (I'd guess maybe ten) that, for whatever reason, are just slightly proud of flush. I've been tweaking my technique as I've gone on and I think I've improved as this step has gone along, but now I'm trying to figure out if I should do anything about the proud rivets.
To be clear, they are barely raised--none are grossly out of whack. I don't think that it's worth the risk or hassle to drill any out, but I've been doing a lot of reading about rivet shaving using a high-speed countersink cage, a shaving bit, and a die grinder (none of which I currently own). I know I'd need to practice a whole bunch on scrap before even attempting this on the spar.
So here's my question: is this worth the effort? This whole area will be covered by skins, so I'm not concerned about aesthetics, just want to know if there's a structural problem with a handful of these being slightly raised.
I tend to think it's not worth bothering with and should just let it go, but I don't want to risk some sort of fatigue cracking. Should I work to make this perfect, or just move on?
