If you needed to put a hemisperical end on a bunch of 1/4" stainless
dowels how would you tackle it? Say 400, give or take.

Take an appropiate radius corner rounding end mill, and use a collet tool
holder to hang onto it on the lathe. Rotate it and adjust the height so
you can use it as a form tool.
