When I was experimenting with the sight leveling tool, I realized that the size of the dovetail can vary well beyond the tolerances for a press fit. I can't remember how much of a taper I put on it (3-4/1000" in 4"?), but it was still just barely enough for the barrels I tried it on.

I'm not sure how they solved this in the factories, but one or two quick strokes with an angled file would cut a taper wide enough to start the sight blade. This is what I would do for a DIY job, and it might be what they had to do in the factories as well. Unless it's the sight blade being tapered... It's kind of difficult to measure, so I don't know for sure.
