Worked the skin and bulk heads somemore and I guess its ok. I may end up with a 20 thousandths shim under the skin at the bulk heads to push the low spot out. Additionally the section between the F808 and F809 is a little oil canny. I don't like this. I may need to make and install a single brace in the middle to stiffen this up. I will also install the Comm antenna hear so the extra brace will help with that.
