The primary RA-washer continued; for the inner diameter, I had to make certain to clear the very edge of the sealed bearing. Its bevelled, sloped edge is slightly higher than the rim surrounding it, and easy to miss...
To slightly enlarge any inner diameter, I hold the washer in my hand whilst lightly rolling the sanding-drum round and round. I have done this for the outer diameters as well.

The washers, during their craftings, are invariably very-lightly scratched here and there, yet in the end are smoothed with the fine steel-wool and lemon-oil. After the grease is applied, they effectively disappear.
Test-fitting...
That, yea, that is where the Earth stands still.
