Hi,

I'd change Beam.length-fraction:


Extended example from NR:

\relative c' {

  \override Beam.length-fraction = 2

  \override Beam.grow-direction = #LEFT
  \featherDurations #(ly:make-moment 2/1)
  { c16[ c c c c c c c] }
  \override Beam.grow-direction = #RIGHT
  \featherDurations #(ly:make-moment 2/3)
  { c32[ d e f] }
  % revert to non-feathered beams
  \override Beam.grow-direction = #'()
  { g32[ a b c] }
}

HTH,
  Harm
