Spar Countersinking Finished

Today I was able to finish up the spar countersinking and I am happy how it turned out. I went over them again and again and verified the size of each countersink on both left and right spars. I ended up making them a bit larger than .370, once I verified the sample dimpled aluminum piece torqued down correctly. I am hoping that it turns out perfect when the tanks go on. Primed all the areas where the anodizing was removed and am now ready for the next step.
The countersinking took much longer than I expected, but I think it is a pretty key point and I wanted to make sure it was as perfect as I could get it.
