I spoke too soon. What I thought were good swages with just the tools and manual tapping were not, upon closer inspection. I found a way to get a good swage, but again it involves using a center punch before applying the staking tool.
Here is one of what I thought was a good swage obtained with just the tool and swiveling it around while tapping it with a small steel block:
Closer observation, and pausing during the swage process to check on the eyelet progress, revealed that it's not actually flaring outwards and instead is sort of folding itself in half as depicted below.
I was able to get a good swage that rolled outwards, but only after I first did the swiveling motion with a 1/4" center punch to get a nice even flare before following up with the staking tool. Comparison between the center punch + 1715 (left) and only the 1715 (right) in the picture below. The stuff sticking out of the left eyelet is just some debris that got caught inside while handling, and isn't an artifact of the swaging process.
So, back to the drawing board it seems. Current guess is that I'm leaning the 1715 too much while swiveling it, meaning that instead of the cone contacting the edge and flaring it the circular groove is smooshing the edge inwards so that it starts rolling in on itself as seen in the drawings. This whole thing feels like when you miss a negative sign early in a physics problem, but everything else checks out so you end up chasing your tail until you find where you flipped the sign. I wonder where I dropped the sign, metaphorically, in this problem... At least I've got a good puzzle to work through.
