It may be worth joining a few email groups (they're posted somewhere in this forum), as well as the various related Facebook groups--there's a fair amount of traffic on those media, more than on this forum.

Fair enough.  If .070" is an acceptable error between the drawings, I won't make any more fuss about it.

I think we may be talking past each other.  I measured the distances digitally (i.e. counting pixels) in the scans *before* printing, and that's where I found the slight discrepancies.  Once I scaled the images so that the tick marks were separated by the correct number of pixels, I printed them and measured the physical (paper) prints.  The physical prints matched the (scaled by me) images, indicating that the print was accurate to my source file.  The hand-marked measurements on the paper (e.g. the 16.5") were spot-on.  By the associative property (which I somehow remember from the first few days of Algebra), since the prints are correct (in those measurements), and the prints are true to their digital source files, the digital source files are also correct with regard to those reference distances.

FWIW, I did this on a per-page basis, since there are slight differences in the scanning errors from page to page.

I've heard of a few builders building the fuselage a couple inches wider, while leaving everything else (wingspan, etc) the same.  There's a bunch of extra work involved, since you have to figure out how the center section spar, upper longerons, aluminum extrusions, and engine mount interface with each other, but it's been done.

A Dragonfly airframe, unfinished, for $7k?  Seems a mite steep, even if the workmanship is really good:

It's been long enough that I don't recall the exact numbers, but I'll explain what I did.  I opened the TIFF files in GIMP, and measured the distance (in pixels) between the tick marks on the page, comparing them to an expected value.  For example, if the distance on the page was marked as 16.5", and the resolution is 150dpi, I would expect the tick marks to be separated by 2475 pixels.  Instead, I found that the tick marks were 2483 pixels apart.

What, specifically, are you measuring to get "22.26 wide at the bottom and 22.33 wide at the top"? You are comparing the images to what you printed from them, or a different set of prints, or what? I'm just trying to understand.

After I did the minor rescaling, I printed them and laid them out on a work bench, and that's where I noticed the templates not lining up.  So I measured them as printed, and then (as I recall) went back to the scans and measured them in GIMP.  The prints were consistent with the image, and both had the same inaccuracy.
