To answer my own question:
changing:
  \clef bass

to:
  \set Staff.clefGlyph = #"clefs.F"
  \set Staff.clefPosition = #1
  \set Staff.middleCPosition = #8

did the trick.

Now I have to find some more tricks to achieve my following goal:
I need to change the spacing between the upper and the lower staff, so 
that the position of the middle c (c') is exactly in the middle between 
the two staffs, and the distance between c' and e' (upper staff) and c' 
and a (lower staff) is exactly the same as between for example e' and g'.
In other words I need proportional vertical notation across the whole 
2-staff system.

(B.T.W:  Maybe you are curious what I'm trying to do? I want Lilypond to 
print music staffs that will be cut out from the paper, the notes will be 
perforated to holes. The strip of (thick) paper will be inserted in a 
small music-box that I have. The wholes in the paper will trigger small 
metal pins and the music will play! This will also require proportional 
notation horizontally. And very exact changing of the staffsize. Some more 
things in the manuals I have to study :-) )
