A very productive day! I found out that I couldl locate and align each of the cross tie/vert channel as an assembly.This will be much easier than trying to rivet them in place. Image 1 is a photo of the 2nd cross tie/vert channel assembly deburred and cleaned. Ready to rivet. Each of the preceding assemblies has been temmporarilllyl installed prior to riveting. Image 2 shhows the aft fuslage looking aft with the 2nd cross tie/vert channel assembly removed.
