Found out mid morning that my 92 year old uncle passed away last night. I'm 55 now, so my parents and their peer group are of the age where it seems like somebody is dying every week. That was on my mind, so I only accomplished a couple of relatively simple tasks, then spent the rest of the day on non-airplane stuff. I fabricated the F-7103C-L&R angles and match drilled them to the panel per print 24. I took my time and crept up on the correct location and depth of fluting to get them to conform to the curve at the upper edge of the panel as closely as possible. I also deburred the F-7103B-L&R attach angles. I can't find anywhere in the build instructions where it tells you to install these, but thinking thru it logically, I don't see how you can correctly locate the F-721B & C flanges that attach the base of the instrument panel to the canopy deck unless the bottom corners of the panel are positioned correctly fore/aft by being clecoed to the skin via these angles. Also discovered that the F-7108B angle is sticking up past the rib/skin flange on it's aft end. Marked it for trimming later. Next time I will re install the skin and hopefully finish up this sub-structure.
