Not much to show for a lot of effort today. The front top skin was an absolute bear to get in place and match drill. Finally, almost 5 hours later and after the 100th time taking it on and off, I was able to get it close enough by heating up the skin and using ratchet straps. I still couldn't get the forward hole on each side to match up with the existing firewall flange hole though (it was off by about 1/2 hole). I decided to just upsize those holes to a 4- rivet instead of a 3-.
I clecoed all of the subpanel pieces in place and match drilled them all. Every last one of them fits incredibly tight. At times I had to pull out the hammer and a block of wood to get things lined up. I clecoed the panel back on in order to line it up on the sides and figure out where the side attach angles go. I'll pick up there another day. This skin issue was super frustrating, so I know if I keep going I'll probably end up making a mistake! I only have a few pieces left on the front deck before I can pull everything apart, clean up the edges and prime. The top skin will be the last skin put on in the entire build. I'll wait to rivet it on until all of my avionics are installed, just to make access easier.
