Remade F20-09R because I had the bend radius too far up the part. I had bent this prior to making the bending tool, so I got a bit tighter radius as well. Installed the F20-09R and finished pilot drilling the one on the left side as well. Installed the center splice plate and the forward clip that is behind it. Installed the left side #4 former. The formers require a lot of tweaking, and even so, I think I will need to make some spacers to avoid dimples on the outer skin. The #4 former is probably the most difficult to drill since part of it is done from inside the aft bay (the smallest one).
