I finished locating and drilling the left side rib attach angles. As I worked on the left side I realized I forgot to do the 2 back rib attach angles on the right side.
I reassembled the right rear spar and made the corrections and added the 2 back rib attach angles. I then dissembled both rear spars and deburred the rib attach angles.
Rear spars are now ready for primer pre-treatment and priming.
