what about using a slit saw mounted in the spindle, cutting slots in
the wheel mounted in a horizontal-axis rotary table?
Of course few of us have motorized rotary tables, but manual as it is,
it should be possible to get finer slots than what endmills can cut.

I have had this problem before. My issue was that the file was not

if you can work in 35mm space, make a large laser print of the wheel,
photograph it a few stops under exposed, over develop it, and cut the finished
disk out of the negative. works for crude diffractive lenses too.

Aah, wet process photography!
What you might do is to get some gelatin emulsion lito film sheet at big
enough size and put into warm water. The emulsion will slide off the film
and you can transfer it to the glass where it will stick. Lito is good
