Brief Description: Part prep - firewall/bottom skin pick ups
I finished the prep on the firewall assembly. Deburred all the holes and dimpled the stainless.
On the bottom forward skin I forgot to roll the aft edge for a good fit against the middle bottom skin. It's a little harder with the thick sheet metail and having already dimpled the near row of holes but I got it done.
Also, I had dimpled two holes on each side that get universal and not flush rivets. The squeezer does a good flattening the dimples.
