Big day...finally have a couple of days off to work on the plane. Finished up 6-2 step 2 and pressed on with steps 3-6. Step 6 was stressful...drilling and what not aren't a problem, but was my first time doing a machine countersink and even after I practiced on some scrap aluminum left over from the spar caps, I still managed to slightly oversink the first couple of holes. I have a good readjustment done now, so the rest of the holes went well. Continued on with 6-3 step 1-2...will continue with step 2 tomorrow...first skin!
