Pulled the sheets out of the rack that I cut a while back and clamped them together with the top edge hanging over the bench. They appear to be oppsite hands so one layout and drilling through both pieces at the same time will make them the same.
Added all the incremental dimension and came up with absolute dimensions for all the rivet lines.
With the layout hanging over the bench it is easy to square and extend the lines.
This layout actually takes two of the prints, 6-b-3 and 6-b-4 for the rivet spacing at the very rear of the fuselage.
