While I was working on the forward bottom skin, I also did some finish work on the side skin. I back-drilled the rest of the holes at the firewall weldments. I trimmed the upper and lower edges of the skin at the upper and lower longeron ahead of the carrythough. I also drilled everything out to the final rivet size (I had drilled everything with a #40. I still have a few holes along the upper longeron to drill out, but that will just take a minute.
I also made the cutout for the aileron control pushrod.
I pulled the plastic off the inside of the skin and got a jump on hole deburring.
