For unknown reasons I don't see your posts on the mailing-list, thus
answering through the nabble-interface...
Probably below may do what you want, although I've no clue what you're
trying to achieve.
See the last example, strange, to say the least.
\override NoteHead.stem-attachment =
(let* ((stem-attach (ly:note-head::calc-stem-attachment grob))
(stem (ly:grob-object grob 'stem))
(stem-thick (ly:grob-property stem 'thickness))
(layout (ly:grob-layout grob))
(line-thick (ly:output-def-lookup layout 'line-thickness))
(blot (ly:output-def-lookup layout 'blot-diameter))
(stem-dir (ly:grob-property stem 'direction)))
(if (and (ly:grob? stem) (< stem-dir 0))
(- (+ blot (* stem-thick line-thick)) (car stem-attach))
(- (cdr stem-attach)))
