Also, the tail edge of the top was now swallow-tail-shaped (yellow line in reference image a few frames back). The drawing is exaggerated, but the actual measurement of the discrepancy was a full 1/8"...couldn’t ignore that; it definitely needed to be reckoned with.

The fillet for the tail wire had to be re-cut. I got to use one of my old-time tools for this. (I love it when I get to use them!) I keep them in good tune and they work really well. I had one that was the perfect tool for the job, a "moving filletster". This plane has a skewed iron for cutting across grain, a little slicer that travels ahead of the iron to prevent the side of the fillet from getting all torn up, and both width and depth stops, to stop you when you're there. You can't go wrong with Movin' Phil! Here's a shot of this great old tool at rest.
