Lathe attachment for horizontal milling, or slot milling
So, about a year ago I bought a little high-speed spindle motor/collet from eBay, to build a CNC cutter/mill. That never happened, but when a friend gave me a lathe as a project I thought about how I could use it on a lathe.
1) Bolted to an old lathe's slide, as an accurate drill?

That was with a Dremel style HSS burr, to remove broken bolts from a vice, that failed to "EzyOut."
2) Bolted in a different way to an old lathe, as a tiny grinder?

Another Dremel tool, cutting slits in a "new" vice jaw.
3) In a lathe tool holder, as a weird horizontal mill?
Step one, fabricate (or get someone to CNC) a bracket to fit your tool post..

Step two, use toolpost height adjustment (or shims) to align to centre, as with any tool, and use it to mill, drill, slot, or grind anything in your chuck. Here I am milling radial slots in a face plate:

I have a clamp and an inclinometer on the plate.
Other possible uses?
4) Turn it around, like a parting tool, and you can drill holes through the middle of a machined shaft for split pins etc.
Same for cutting parallel slots.
5) Fit a little grinding wheel, and you can (slowly) refinish hardened or carbide centres, polish collets, et c.
6) Castellated nuts? No problem!
