I continued deburring yesterday and today. The holes inside the flanges took extra time to debur because my deburring tool won't fit in that space. After finishing all the holes I started with deburring edges. There's still some more work to do there, but I'm getting through it.
I need to send a HUGE thank you to my tech counselor for his assistance with my first mistake. After I disassembled the rear spar, I noticed two of the three holes for the center rib attachment were a complete mess. After panicking for about 20 minutes, I considered trying to make a doubler to go over the area and sandwich the bad holes between the doubler on the back of the spar and the one I planned to make on the front. I reached out to my tech counselor for his advice, and he had a much simpler solution for me.
“drill two new holes providing at least one hole diameter edge distance from existing and rivet then clean up the bad holes and rivet them too. … take a longer rivet and slightly squeeze it to shorten it and make it a larger diameter then insert and complete rivet. If match hole drilling, this issue is usually caused by only clecoing one hole. Cleco two, drill, move cleco and drill.“
I took the advice of my tech counselor, and I'm very pleased with how it turned out! Thank you!
