thanks, i'll check that out. and if anyone else is interested, i also found this, http://archerprecision.ca/, where the machinist/owner assures me what i'm looking for seems pretty simple. i look forward not only to making spherical ice cubes, but also lording it over others as to why that shape is thermodynamically optimal for cocktails. :-) rday -- ======================================================================== Robert P.
