Bellville washers, also known as Schnorr springs are just that - springs. I used to use spherical seat washers at work that were a male/female pair with a part spherical face. You'd want to use just the male half, but I expect need to buy them as pairs. Not sure where they came from, but it was possibly WDS, ask in an engineering fasteners or maybe bearing supplies.

Yep. Too large. :(
Yep. I want to remove moles from my family for a fee.
I'd pay for a good quality, properly sized tool.
OK, now I'm dyin' to know what it's for...

_ was thinking very hard :
I needed a mismatched hub and rim once. I had these guys make the spokes to fit.

If you find me one, I'll tell you. :)
The only "simpler solution" I see would be a spherical cutter (to make the dimple into a sphere of some standard radius) in conjunction with a spherical-head nipple. The spherical cutter (just a custom-ground drill) is relatively easy, and some machine shops with NC lathes could turn the special nipples out easily enough.
I suspect the washer solution would leave you with a nipple that has high stress (and fractures) or with a nipple that finds the center of the dimple with its head, and the center of the hole with its shaft, and STILL points wrong.
The aimed-drill idea doesn't always take math, you might be able to put a laser pointer in the drill press chuck, and align a rim-clamp jig using that.
