I'm looking for an 8mm diameter steel ball (well, lots of them, actually). I want to drill a hole in it to fix to the end of a shaft and most steel balls I can find, which are hardened for use in bearings, probably wouldn't be the easiest to drill. F H Brundle do "ball nuts" with a threaded hole but only down to 12mm.
I've also seen this sort of thing which could be made to do the job but would lead to a more complicated design (and slightly more expense).
Any ideas where to look?
