I finally gave up on getting my aircompressor up to the task so I picked up a nice 60 gallon belt-drive unit and got it set up.
I didn't get a picture, but after I drilled the left side skin to the tailcone, I then backdrilled through the bottom skin at the overlap joint.
I then fitted, marked, and removed the right side skin. I then laid out my rivet patten and pre-drilled the skin. I place the skin back onto the structure and started match drilling.
Before I could finish drilling my new higher-pressure compressor blew my regulator apart which included my water separator. That was it for that day.
