Spent about 2 hours drilling all the holes to #30. Drilled the inside of the spar box to the aft angles on each side using the 12" drill bits. Took a break. Spent about another hour drilling the bolt holes to #11. Only things left to drill for the F11 print are the gussets on the floor and firewall square tubes, and the floor square tube to the bottom skin. I'll drill that square tube with the bottom skin off the rest of the assembly.
