Missed yesterday, out sick.
Finish match drilling center bottom skin. Went quick, since the clecos were all set and I just needed to drill the last holes.
Trim 623 corner ribs to length. These cause a lot of consternation, since the instructions are kind of vague and the details are not sufficient to figure out exactly what to do. I don't think it's super critical to get it to the thousandth. All the web sites describe the tribulations, and they helped alot. The 7 build sites are usable here, since the 7 and 9 fuselages are nealy identical from 705 back.
Fabbed the attach straps for the 623. Got to do it twice because the first piece of material was .032, but that included two layers of plastic. So now I have a nice set of .025 shims! The fact that these straps are made from such thin material, and only held by a few #40 rivets shows that the 623 ribs are really just to help set the external shape of the skin. They can't be carrying very much load.
